Question 1

1. It uses a transition like “Finally,” which makes it confusing.
2. It introduces new information about penguins flying, not explained in the body. (correct answer)
3. It restates the main idea and summarizes key adaptations, so it is too long.
4. It repeats one key point from the body, so it cannot be a conclusion.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—"Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Chen writes an explanation about penguin adaptations. The body includes how penguins adapt to cold environments. The explanation has a conclusion that introduces new information about penguins flying, which was not explained in the body. Choice B is correct because Chen's conclusion introduces new information about penguins flying, not explained in the body. Conclusions should wrap up what was already explained, not bring up entirely new facts. Chen could improve by removing the new information and instead summarizing what was explained about penguin adaptations to cold, such as "These special features help penguins survive in freezing Antarctic waters." Choice A is incorrect because using a transition like "Finally" is actually helpful in conclusions, not confusing. Choice C incorrectly claims that restating and summarizing makes a conclusion too long, when these are exactly what conclusions should do. Choice D misunderstands that conclusions can and should reference key points from the body—the problem is introducing NEW information not mentioned before. To help students write effective conclusions for informational/explanatory writing: Teach the rule "No new major facts in conclusions"; use a T-chart comparing Good Conclusions (restate, summarize, final thought) vs Poor Conclusions (new facts, off-topic, too brief). Model revision: "Chen wrote about flying in his conclusion, but that wasn't in his body. Let's revise to summarize what he DID explain about cold adaptations." Practice with examples: "Which conclusion fits? A) 'Penguins also eat fish' (new fact) or B) 'These adaptations help penguins thrive in icy habitats' (summarizes)." Use highlighting: highlight body facts in one color, conclusion in another—check that conclusion color only wraps up body color facts. Watch for: students who save their most interesting fact for the conclusion; students who think conclusions must add something "extra" beyond summarizing; students who don't understand the difference between developing ideas (body) and wrapping them up (conclusion); students who want to impress readers with one more fact instead of providing closure.

Question 2

1. Draft 1 ends, “Seeds need water and sunlight,” and stops right there.
2. Draft 2 ends, “Now you know plants need water, light, and time to grow strong.” (correct answer)
3. Draft 1 is better because it ends faster and uses fewer words.
4. Draft 2 is worse because it restates the main idea instead of adding new facts.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—"Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Keisha writes an explanation about plant growth in two drafts. Draft 1 ends "Seeds need water and sunlight" and stops right there. Draft 2 ends "Now you know plants need water, light, and time to grow strong." Draft 2 has a concluding statement while Draft 1 ends abruptly. Choice B is correct because Draft 2 ends "Now you know plants need water, light, and time to grow strong" which uses the transition phrase "Now you know" and restates the main ideas about what plants need to grow. This wraps up the explanation effectively. Draft 1 wraps up worse because it ends after "Seeds need water and sunlight" without any concluding statement, leaving the reader without closure. Effective conclusions wrap up the explanation, don't introduce new major information, and connect back to the topic. Choice C is incorrect because it claims Draft 1 is better for ending faster and using fewer words when actually Draft 1 lacks a conclusion—just stopping after a detail doesn't wrap up the explanation. Students sometimes think shorter is always better and don't recognize when explanation lacks conclusion. To help students write effective conclusions for informational/explanatory writing: Teach conclusion formula explicitly: "Restate + So What" or "Summary + Final Thought"; model with think-aloud: "I explained what plants need to grow (water, light, time). Now I'll wrap up by restating: 'Plants require these three things to thrive.' Final thought: 'Understanding plant needs helps us become better gardeners.'" Show difference between introduction (This explanation is about...) and conclusion (Now you know that...); practice "Turn your introduction into a conclusion" by changing from future to past tense (will explain → explained/shows); post conclusion transition words: In conclusion, Finally, To sum up, Now you know, As you can see, Therefore, This shows that, In the end. Use "conclusion checklist": Does it restate main idea (not word-for-word)? Does it summarize key points? Does it provide final thought? Does it use transition word? Does it connect to topic? Does it avoid introducing major new information? Practice identifying strong vs weak conclusions with examples. Watch for: students who just stop after last detail without concluding; students who think shorter is always better; students who don't recognize that explanation lacks conclusion.

Question 3

1. No, because the last body detail about camouflage is the conclusion.
2. Yes, it stops after the last fact and never sums up the main idea. (correct answer)
3. No, because conclusions must always include a question for the reader.
4. Yes, because the introduction should be moved to the end as a conclusion.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—“Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Example: If explanation is about how levers work (fulcrum, less force needed, examples), strong conclusion: "Now you can see how levers use a fulcrum to help us lift heavy objects more easily. This simple machine makes our work easier every day." (restates main idea + final thought). Weak conclusion: "Done." (too brief, no wrap-up). Weak: "There are also pulleys and wheels." (new information, doesn't conclude about levers). Missing conclusion: explanation just stops after last example without any wrap-up sentence. Yuki writes an explanation about chameleon adaptations. The body includes facts about camouflage and other adaptations. The explanation ends abruptly after the last detail about camouflage without any wrap-up. Choice B is correct because Yuki does NOT include a concluding statement—the explanation ends after the last detail without any wrap-up, leaving the reader without closure. Choice A is incorrect because it confuses the last body detail with a conclusion when it doesn't restate or summarize. Students sometimes confuse adding more facts (body development) with wrapping up (conclusion). To help students write effective conclusions for informational/explanatory writing: Teach conclusion formula explicitly: "Restate + So What" or "Summary + Final Thought"; model with think-aloud: "I explained three ways polar bears adapt to Arctic (thick fur, small ears, wide paws). Now I'll wrap up by restating: 'These special features help polar bears survive in extremely cold environments.' Final thought: 'Understanding these adaptations shows how animals change to fit where they live.'" Show difference between introduction (This explanation is about...) and conclusion (Now you know that...); practice "Turn your introduction into a conclusion" by changing from future to past tense (will explain → explained/shows); post conclusion transition words: In conclusion, Finally, To sum up, Now you know, As you can see, Therefore, This shows that, In the end. Use "conclusion checklist": Does it restate main idea (not word-for-word)? Does it summarize key points? Does it provide final thought? Does it use transition word? Does it connect to topic? Does it avoid introducing major new information? Practice identifying strong vs weak conclusions with examples; provide sentence frames: "Now you know that [main idea]. This [why it matters]." or "In conclusion, [summary of key points]. [Final thought]." Give feedback on common errors: "This conclusion is too brief. Add a sentence restating your main idea." or "This introduces new information. Instead, wrap up by summarizing what you already explained.". Watch for: students who just stop after last detail without concluding; students who write "The end" or "Done" thinking it's sufficient; students who introduce completely new facts in conclusion instead of wrapping up. Common pitfall 2: students who copy introduction word-for-word; students who write vague conclusions ("That's all") that could apply to any topic; students who don't use transition words to signal conclusion; students who think longer conclusion is better even if it doesn't wrap up effectively; students who confuse adding more facts (body development) with wrapping up (conclusion).

Question 4

1. It introduces a new topic about video games and screen time.
2. It wraps up by restating why warming up and drinking water matter. (correct answer)
3. It adds another body detail instead of giving closure.
4. It only tells the reader the title again, with no final thought.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—“Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Example: If explanation is about how levers work (fulcrum, less force needed, examples), strong conclusion: "Now you can see how levers use a fulcrum to help us lift heavy objects more easily. This simple machine makes our work easier every day." (restates main idea + final thought). Weak conclusion: "Done." (too brief, no wrap-up). Weak: "There are also pulleys and wheels." (new information, doesn't conclude about levers). Missing conclusion: explanation just stops after last example without any wrap-up sentence. Marcus writes an explanation about exercising safely. The body includes facts about warming up, drinking water, and other safety tips. The explanation includes a concluding statement that restates why warming up and drinking water matter. The conclusion restates the main idea and provides a final thought. Choice B is correct because the concluding statement wraps up by restating why warming up and drinking water matter, connecting back to the topic. Choice A is incorrect because it thinks the conclusion should introduce new information when it should connect to what's already explained. Students sometimes think adding another fact is same as wrapping up. To help students write effective conclusions for informational/explanatory writing: Teach conclusion formula explicitly: "Restate + So What" or "Summary + Final Thought"; model with think-aloud: "I explained three ways polar bears adapt to Arctic (thick fur, small ears, wide paws). Now I'll wrap up by restating: 'These special features help polar bears survive in extremely cold environments.' Final thought: 'Understanding these adaptations shows how animals change to fit where they live.'"

Question 5

1. No, it ends after details about humps and eyelashes without wrapping up. (correct answer)
2. Yes, because the first sentence introduces camels and that counts as a conclusion.
3. Yes, because the last detail about sandstorms is the same as a conclusion.
4. No, because a conclusion should add new facts about where camels live.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—"Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Emma writes an explanation about camels. The body includes details about their adaptations like humps for storing fat and long eyelashes for protection. The explanation ends abruptly after the last detail about sandstorms without any wrap-up. Choice A is correct because Emma does NOT include a concluding statement—the explanation ends after the detail about eyelashes and sandstorms without any wrap-up, leaving the reader without closure. Emma should add a concluding statement that restates the main idea or summarizes key points to wrap up, such as "In conclusion, these special features help camels survive in harsh desert conditions." Choice B is incorrect because it confuses introduction (which introduces topic) with conclusion (which wraps up). The first sentence introduces the topic but doesn't conclude anything. Choice C incorrectly thinks the last detail about sandstorms is the same as a conclusion, when it's just another fact without any wrap-up language. Choice D misunderstands that conclusions should connect to what's already explained, not introduce new facts about where camels live. To help students write effective conclusions for informational/explanatory writing: Teach conclusion formula explicitly: "Restate + So What" or "Summary + Final Thought"; model with think-aloud: "I explained how camels adapt to deserts (humps, eyelashes). Now I'll wrap up by restating: 'These adaptations help camels thrive in desert environments.'" Show difference between introduction (This explanation is about...) and conclusion (Now you know that...); practice "Turn your introduction into a conclusion" by changing from future to past tense; post conclusion transition words: In conclusion, Finally, To sum up, Now you know, As you can see. Use "conclusion checklist": Does it restate main idea? Does it summarize key points? Does it provide final thought? Does it use transition word? Does it connect to topic? Does it avoid introducing major new information? Practice identifying strong vs weak conclusions with examples. Watch for: students who just stop after last detail without concluding; students who think any last sentence counts as conclusion; students who confuse adding more facts with wrapping up.

Question 6

1. Plants come in many green shapes and colors all around the world.
2. In the end, seeds, water, sunlight, and time help plants grow into adults. (correct answer)
3. First, a tiny seed is planted deep down in the warm soil.
4. A plant is a living thing that needs water and air to stay alive.

Explanation: A good conclusion wraps up the whole explanation. It should remind readers of the main points and use a signal word to show the writing is ending. The sentence about seeds, water, sunlight, and time working in the end does this best. It uses the wrapping-up phrase "In the end" and pulls together all the key ideas Amir explained about plant growth, giving readers a sense of completion. The sentence about green shapes and colors around the world adds a brand-new fact that Amir never explained, so it does not wrap up his writing. The sentence about a tiny seed being planted in warm soil uses the word "First," which starts an explanation instead of ending one. The sentence about a plant needing water and air only gives one detail and reads like an opening definition, not a summary of everything he explained. Remember: a conclusion looks back and pulls the whole explanation together, so "In the end, seeds, water, sunlight, and time help plants grow into adults" is the best choice.

Question 7

1. Yes, she ends with “The end,” which clearly summarizes camel adaptations.
2. No, her writing stops after details and never restates the main idea. (correct answer)
3. Yes, the first sentence is the conclusion because it introduces camels.
4. No, she should add a new fact about where camels live to conclude.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—“Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore).

Example: If explanation is about how levers work (fulcrum, less force needed, examples), strong conclusion: "Now you can see how levers use a fulcrum to help us lift heavy objects more easily. This simple machine makes our work easier every day." (restates main idea + final thought). Weak conclusion: "Done." (too brief, no wrap-up). Weak: "There are also pulleys and wheels." (new information, doesn't conclude about levers). Missing conclusion: explanation just stops after last example without any wrap-up sentence. Emma writes an explanation about camels. The body includes facts about camel adaptations such as humps for storing fat, long eyelashes to keep out sand, and wide feet for walking on sand. The explanation ends abruptly after the last detail without any wrap-up. Choice B is correct because Emma does NOT include a concluding statement—the explanation ends after the last detail without any wrap-up, leaving the reader without closure. Choice A is incorrect because it claims "The end" summarizes adaptations when it's too brief and doesn't restate or summarize anything. Students sometimes forget to add a conclusion and just stop after the last detail. To help students write effective conclusions for informational/explanatory writing: Teach conclusion formula explicitly: "Restate + So What" or "Summary + Final Thought"; model with think-aloud: "I explained three ways polar bears adapt to Arctic (thick fur, small ears, wide paws). Now I'll wrap up by restating: 'These special features help polar bears survive in extremely cold environments.' Final thought: 'Understanding these adaptations shows how animals change to fit where they live.'" Show difference between introduction (This explanation is about...) and conclusion (Now you know that...); practice "Turn your introduction into a conclusion" by changing from future to past tense (will explain → explained/shows); post conclusion transition words: In conclusion, Finally, To sum up, Now you know, As you can see, Therefore, This shows that, In the end. Use "conclusion checklist": Does it restate main idea (not word-for-word)? Does it summarize key points? Does it provide final thought? Does it use transition word? Does it connect to topic? Does it avoid introducing major new information? Practice identifying strong vs weak conclusions with examples; provide sentence frames: "Now you know that [main idea]. This [why it matters]." or "In conclusion, [summary of key points]. [Final thought]." Give feedback on common errors: "This conclusion is too brief.

Question 8

1. Add a final sentence that summarizes benefits, like stronger muscles and a healthier heart. (correct answer)
2. Replace the conclusion with a question about a different topic, like video games.
3. End with “I hope you liked it,” because opinions are the best way to conclude.
4. Add new facts about nutrition that were not explained in the body.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—"Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Marcus writes an explanation about exercise. The body includes information about benefits of exercise. The explanation needs improvement in its conclusion. Choice A is correct because Marcus could improve by adding a final sentence that summarizes benefits like stronger muscles and a healthier heart—this would restate the main ideas about exercise benefits and provide closure to the explanation. For example: "In conclusion, regular exercise strengthens your muscles and keeps your heart healthy." Effective conclusions wrap up the explanation, don't introduce new major information, and connect back to the topic. Choice D is incorrect because it thinks conclusion should introduce new information when it should connect to what's already explained—adding new facts about nutrition that weren't in the body doesn't wrap up the exercise explanation. Students sometimes think good conclusion must introduce new facts instead of synthesizing what was presented. To help students write effective conclusions for informational/explanatory writing: Teach conclusion formula explicitly: "Restate + So What" or "Summary + Final Thought"; model with think-aloud: "I explained how exercise helps muscles and heart. Now I'll wrap up by restating: 'Regular exercise provides many health benefits.' Final thought: 'Making exercise a daily habit leads to a stronger, healthier body.'" Show difference between introduction (This explanation is about...) and conclusion (Now you know that...); practice "Turn your introduction into a conclusion" by changing from future to past tense (will explain → explained/shows); post conclusion transition words: In conclusion, Finally, To sum up, Now you know, As you can see, Therefore, This shows that, In the end. Use "conclusion checklist": Does it restate main idea (not word-for-word)? Does it summarize key points? Does it provide final thought? Does it use transition word? Does it connect to topic? Does it avoid introducing major new information? Practice identifying strong vs weak conclusions with examples; provide sentence frames: "Now you know that [main idea]. This [why it matters]." Watch for: students who introduce completely new facts in conclusion instead of wrapping up; students who think longer conclusion is better even if it doesn't wrap up effectively; students who write vague conclusions that could apply to any topic.

Question 9

1. Yes, it ends with “That’s all about my topic,” which signals that the writing is finished.
2. No, it adds brand-new facts about rainforests instead of summarizing what she explained about deserts.
3. Yes, it restates what makes deserts dry and extreme, using the transition phrase “To sum up.” (correct answer)
4. No, it copies her opening sentence word-for-word instead of wrapping the ideas up in a fresh way.

Explanation: A strong conclusion wraps up the explanation by restating the main idea in a fresh way and often uses a transition word. The best answer says the ending restates what makes deserts dry and extreme and uses the phrase “To sum up.” That is exactly what a good conclusion does—it reminds the reader of the main point and signals the finish. The choice about ending with “That’s all about my topic” is wrong because that line just announces you are stopping; it doesn’t restate any of Maya’s ideas, and it could be tacked onto any topic. The choice about adding new facts about rainforests is wrong because a conclusion should wrap up what was already explained, not introduce a brand-new topic—but Maya’s ending stays on deserts, so this choice misreads her writing. The choice about copying the opening sentence word-for-word is wrong because a good conclusion restates the idea in a new way instead of repeating the introduction exactly—and Maya doesn’t do that. Only the answer about restating with “To sum up” matches a truly strong conclusion.

Question 10

1. A new paragraph explaining hurricanes and tornadoes in detail.
2. A concluding statement that summarizes evaporation, condensation, and precipitation. (correct answer)
3. More transition words in the middle, like “first” and “next.”
4. A longer introduction that repeats the title three times.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—“Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Example: If explanation is about how levers work (fulcrum, less force needed, examples), strong conclusion: "Now you can see how levers use a fulcrum to help us lift heavy objects more easily. This simple machine makes our work easier every day." (restates main idea + final thought). Weak conclusion: "Done." (too brief, no wrap-up). Weak: "There are also pulleys and wheels." (new information, doesn't conclude about levers). Missing conclusion: explanation just stops after last example without any wrap-up sentence. Sofia writes an explanation about the water cycle. The body includes facts about evaporation, condensation, and precipitation. The explanation ends abruptly after the last detail without any wrap-up. Choice B is correct because Sofia should add a concluding statement that summarizes evaporation, condensation, and precipitation to wrap up. Choice A is incorrect because it thinks adding new information about hurricanes and tornadoes wraps up when it should connect to what's already explained. Students sometimes introduce completely new information instead of wrapping up what was explained. To help students write effective conclusions for informational/explanatory writing: Teach conclusion formula explicitly: "Restate + So What" or "Summary + Final Thought"; model with think-aloud: "I explained three ways polar bears adapt to Arctic (thick fur, small ears, wide paws). Now I'll wrap up by restating: 'These special features help polar bears survive in extremely cold environments.' Final thought: 'Understanding these adaptations shows how animals change to fit where they live.'" Show difference between introduction (This explanation is about...) and conclusion (Now you know that...); practice "Turn your introduction into a conclusion" by changing from future to past tense (will explain → explained/shows); post conclusion transition words: In conclusion, Finally, To sum up, Now you know, As you can see, Therefore, This shows that, In the end. Use "conclusion checklist": Does it restate main idea (not word-for-word)? Does it summarize key points? Does it provide final thought? Does it use transition word? Does it connect to topic? Does it avoid introducing major new information? Practice identifying strong vs weak conclusions with examples; provide sentence frames: "Now you know that [main idea]. This [why it matters]." or "In conclusion, [summary of key points]. [Final thought]." Give feedback on common errors: "This conclusion is too brief. Add a sentence restating your main idea." or "This introduces new information. Instead, wrap up by summarizing what you already explained.". Watch for: students who just stop after last detail without concluding; students who write "The end" or "Done" thinking it's sufficient; students who introduce completely new facts in conclusion instead of wrapping up. Common pitfall 2: students who copy introduction word-for-word; students who write vague conclusions ("That's all") that could apply to any topic; students who don't use transition words to signal conclusion; students who think longer conclusion is better even if it doesn't wrap up effectively; students who confuse adding more facts (body development) with wrapping up (conclusion).

Question 11

1. Yes, because he ends by naming a new simple machine, the pulley.
2. No, because he ends with “Done,” which does not summarize levers.
3. Yes, because his last sentence restates how levers help lift with less effort. (correct answer)
4. No, because conclusions should repeat the introduction word-for-word.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—“Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Example: If explanation is about how levers work (fulcrum, less force needed, examples), strong conclusion: "Now you can see how levers use a fulcrum to help us lift heavy objects more easily. This simple machine makes our work easier every day." (restates main idea + final thought). Weak conclusion: "Done." (too brief, no wrap-up). Weak: "There are also pulleys and wheels." (new information, doesn't conclude about levers). Missing conclusion: explanation just stops after last example without any wrap-up sentence. Jamal writes an explanation about levers. The body includes facts about how levers use a fulcrum to lift heavy objects with less effort, with examples like seesaws. The explanation includes a concluding statement that restates the main idea. Choice C is correct because Jamal includes a concluding statement which restates the main idea by saying how levers help lift with less effort and connects back to the topic. This wraps up the explanation effectively. Choice B is incorrect because it claims "Done" does not summarize when the actual conclusion restates effectively; students sometimes accept "Done" as effective conclusion when it's too brief and doesn't restate or summarize. To help students write effective conclusions for informational/explanatory writing: Teach conclusion formula explicitly: "Restate + So What" or "Summary + Final Thought"; model with think-aloud: "I explained three ways polar bears adapt to Arctic (thick fur, small ears, wide paws). Now I'll wrap up by restating: 'These special features help polar bears survive in extremely cold environments.' Final thought: 'Understanding these adaptations shows how animals change to fit where they live.'" Show difference between introduction (This explanation is about...) and conclusion (Now you know that...); practice "Turn your introduction into a conclusion" by changing from future to past tense (will explain → explained/shows); post conclusion transition words: In conclusion, Finally, To sum up, Now you know, As you can see, Therefore, This shows that, In the end. Use "conclusion checklist": Does it restate main idea (not word-for-word)? Does it summarize key points? Does it provide final thought? Does it use transition word? Does it connect to topic? Does it avoid introducing major new information? Practice identifying strong vs weak conclusions with examples; provide sentence frames: "Now you know that [main idea]. This [why it matters]." or "In conclusion, [summary of key points]. [Final thought]." Give feedback on common errors: "This conclusion is too brief. Add a sentence restating your main idea." or "This introduces new information. Instead, wrap up by summarizing what you already explained." Watch for: students who just stop after last detail without concluding; students who write "The end" or "Done" thinking it's sufficient; students who introduce completely new facts in conclusion instead of wrapping up. Common pitfall: students who copy introduction word-for-word; students who write vague conclusions ("That's all") that could apply to any topic; students who don't use transition words to signal conclusion; students who think longer conclusion is better even if it doesn't wrap up effectively; students who confuse adding more facts (body development) with wrapping up (conclusion).

Question 12

1. Yes, it adds a new fact not discussed, so it does not truly wrap up. (correct answer)
2. No, it summarizes her bravery and impact and gives a sense of closure.
3. No, because conclusions should always add at least one brand-new detail.
4. Yes, because repeating the introduction word-for-word is the best conclusion.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—"Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Carlos writes an explanation about Harriet Tubman. The body includes information about her bravery and impact. The explanation includes a concluding statement that introduces new information. Choice A is correct because Carlos's conclusion adds a new fact not discussed in the body, so it does not truly wrap up what was already explained. Effective conclusions should synthesize existing information rather than introduce major new details. If the body didn't mention this new fact, the conclusion shouldn't either. Choice B is incorrect because it claims the conclusion summarizes her bravery and impact with closure, but the question indicates the conclusion actually introduces new information, which violates the principle of effective conclusions. To help students write effective conclusions for informational/explanatory writing: Use "conclusion checklist": Does it avoid introducing major new information? Teach students: "Save new facts for the body paragraphs. Use the conclusion to wrap up what you already explained." Model revision: "Instead of adding a new fact about Harriet Tubman, I'll summarize: 'Harriet Tubman's courage helped many enslaved people find freedom.'" Watch for: students who think conclusions should always add new details (Choice C misconception); students who introduce completely new facts in conclusions instead of wrapping up; students who don't understand that conclusions should connect to what was already explained; students who think repeating introductions word-for-word is best (Choice D).

Question 13

1. Another body detail explaining pulleys, because they are also simple machines.
2. A concluding statement that sums up how levers make lifting easier. (correct answer)
3. A longer introduction that repeats the title and adds more sentences.
4. A question asking the reader if they like levers and why.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—"Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Jamal writes an explanation about levers. The body includes information about how levers work and make lifting easier. The explanation ends abruptly after the last detail without any wrap-up. Choice B is correct because Jamal should add a concluding statement that sums up how levers make lifting easier to wrap up, such as "In conclusion, levers help us lift heavy objects with less effort by using a fulcrum." This would provide closure and connect back to the main idea he explained. Choice A is incorrect because it suggests adding another body detail about pulleys, which introduces new information rather than wrapping up what was already explained about levers. A conclusion should synthesize existing information, not introduce new topics. To help students write effective conclusions for informational/explanatory writing: Use "conclusion checklist": Does it restate main idea (not word-for-word)? Does it summarize key points? Does it provide final thought? Does it use transition word? Does it connect to topic? Does it avoid introducing major new information? Practice identifying strong vs weak conclusions with examples; provide sentence frames: "Now you know that [main idea]. This [why it matters]." or "In conclusion, [summary of key points]. [Final thought]." Give feedback on common errors: "This introduces new information. Instead, wrap up by summarizing what you already explained." Watch for: students who think adding more facts (body development) equals wrapping up (conclusion); students who want to add unrelated topics like pulleys when explaining levers; students who confuse longer introductions (Choice C) or reader questions (Choice D) with conclusions.

Question 14

1. Yes, it wraps up by summarizing how penguins stay warm and swim well. (correct answer)
2. No, the introduction is the conclusion because it names the topic first.
3. Yes, any last sentence is a strong concluding statement, even if unrelated.
4. No, a conclusion must add a new fact about penguins not in the body.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—"Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Emma writes an explanation about penguin adaptations. The body includes facts about how penguins stay warm and swim well. The explanation includes a concluding statement that wraps up by summarizing these adaptations. Choice A is correct because Emma includes a concluding statement that summarizes how penguins stay warm and swim well, which restates the main ideas from the body of her explanation. This wraps up the explanation effectively by connecting back to the key adaptations she explained. Choice B is incorrect because it confuses introduction (which introduces topic) with conclusion (which wraps up). The introduction and conclusion serve different purposes—the introduction presents what will be explained while the conclusion summarizes what was explained. To help students write effective conclusions for informational/explanatory writing: Teach conclusion formula explicitly: "Restate + So What" or "Summary + Final Thought"; model with think-aloud: "I explained how penguins stay warm (blubber, feathers) and swim well (flippers, streamlined body). Now I'll wrap up by restating: 'These adaptations help penguins survive in cold water.' Final thought: 'Understanding these features shows how animals are perfectly designed for their environment.'" Show difference between introduction (This explanation is about...) and conclusion (Now you know that...); practice "Turn your introduction into a conclusion" by changing from future to past tense (will explain → explained/shows). Watch for: students who confuse the introduction with the conclusion; students who think any last sentence counts as a conclusion even if unrelated (Choice C); students who think conclusions must add new facts not in the body (Choice D).

Question 15

1. Ending 1: “Pulleys use a rope and wheel to lift loads.” Ending 2: “Done.”
2. Ending 1: “The end.” Ending 2: “That’s all about my topic.”
3. Ending 1: “There are also levers and wheels.” Ending 2: “Pulleys are in ancient Egypt.”
4. Ending 1: “Finally, pulleys make lifting easier by changing the direction of force.” Ending 2: “I like recess.” (correct answer)

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—"Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Yuki writes an explanation about pulleys. The body includes how pulleys work to make lifting easier. The explanation has two possible endings to compare. Choice D is correct because Ending 1 "Finally, pulleys make lifting easier by changing the direction of force" wraps up better—it uses a transition word, restates the main idea about how pulleys work, and connects to the topic. Ending 2 "I like recess" is completely unrelated to pulleys and doesn't wrap up anything that was explained. Choice A's Ending 1 is better than "Done," but it's just restating a basic fact rather than wrapping up how pulleys help us. Choice B presents two equally weak endings—both are too brief and vague without referencing the topic. Choice C shows two endings that both introduce unrelated information instead of wrapping up pulleys. To help students write effective conclusions for informational/explanatory writing: Teach comparison skills—put two endings side by side and analyze which better meets conclusion criteria; model thinking aloud: "Ending 1 talks about pulleys and how they work. Ending 2 talks about recess—that's not even related! Ending 1 wins." Practice with sorting activities: Which endings belong with which topics? Which endings are off-topic? Use checklist for comparison: Related to topic? Wraps up main idea? Uses transition? Provides closure? Create "Conclusion Court" where students defend why one ending is better than another using evidence. Watch for: students who think any ending is fine as long as it's last; students who can't identify when conclusions are completely off-topic; students who don't see the difference between weak ("Done") and strong (topic-specific wrap-up) conclusions; students who think personal opinions ("I like...") can replace topic conclusions.

Question 16

1. “Pulleys are a simple machine. Pulleys are a simple machine.”
2. “In the end, pulleys help lift heavy loads by changing the direction of force.” (correct answer)
3. “That’s all about my topic.”
4. “Also, wheels are used on bikes and cars, and that is important too.”

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—"Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Yuki writes an explanation about pulleys. The body includes information about how pulleys work as simple machines. The explanation needs a strong concluding statement. Choice B is correct because "In the end, pulleys help lift heavy loads by changing the direction of force" is the best concluding statement—it uses the transition phrase "In the end" and restates the main idea about how pulleys work by summarizing their key function. This wraps up the explanation effectively. Conclusion A repeats the same phrase twice without adding meaning, Conclusion C is too vague ("That's all about my topic") and doesn't reference pulleys specifically, and Conclusion D introduces new information about wheels instead of wrapping up about pulleys. Effective conclusions wrap up the explanation, don't introduce new major information, and connect back to the topic. Choice D is incorrect because it introduces new information about wheels and cars when conclusion should connect to what's already explained about pulleys—adding information about a different simple machine doesn't wrap up the pulley explanation. Students sometimes think conclusion should introduce new information when it should synthesize what was already presented. To help students write effective conclusions for informational/explanatory writing: Teach conclusion formula explicitly: "Restate + So What" or "Summary + Final Thought"; model with think-aloud: "I explained how pulleys change direction of force to lift heavy things. Now I'll wrap up by restating: 'Pulleys make lifting easier by redirecting force.' Final thought: 'This simple machine helps us move heavy objects we couldn't lift alone.'" Show difference between introduction (This explanation is about...) and conclusion (Now you know that...); practice "Turn your introduction into a conclusion" by changing from future to past tense (will explain → explained/shows); post conclusion transition words: In conclusion, Finally, To sum up, Now you know, As you can see, Therefore, This shows that, In the end. Use "conclusion checklist": Does it restate main idea (not word-for-word)? Does it summarize key points? Does it provide final thought? Does it use transition word? Does it connect to topic? Does it avoid introducing major new information? Practice identifying strong vs weak conclusions with examples. Watch for: students who copy introduction word-for-word; students who write vague conclusions ("That's all") that could apply to any topic; students who introduce completely new facts in conclusion instead of wrapping up.

Question 17

1. Yes; it says, “Did you know hurricanes form over oceans?” adding an exciting new fact to end on.
2. No; it says, “Also, water can evaporate from puddles,” which just adds one more detail without a final thought.
3. Yes; it says, “To sum up, water evaporates, condenses, and falls as rain,” connecting back to the topic. (correct answer)
4. Yes; it says, “The clouds get heavy and drop rain down,” and that last body fact works fine as an ending.

Explanation: The best answer is the one that summarizes the whole water cycle with the phrase “To sum up,” listing evaporation, condensation, and rain. A strong conclusion pulls the main ideas together and signals the reader that the explanation is ending—this one does both, so it wraps up effectively. The choice about hurricanes forming over oceans is wrong because a conclusion should not introduce a brand-new topic the body never explained; hurricanes are not part of Sofia’s water cycle explanation, so it doesn’t wrap anything up. The choice about water evaporating from puddles is wrong because it just tacks on one more body detail instead of giving a closing thought or summary—it leaves the reader hanging. The choice about clouds dropping rain is wrong because a final body fact is not the same as a conclusion; it explains one step but never signals the ending or ties the ideas together. Only the summarizing sentence with “To sum up” actually closes the explanation.

Question 18

1. It introduces a new topic about vitamins and minerals not discussed earlier.
2. It wraps up by summarizing benefits and connects back to the main idea. (correct answer)
3. It replaces the body by adding more details about each type of sport.
4. It works as an introduction because it tells what she will explain next.

Explanation: This question tests 4th grade informational/explanatory writing skills: providing a concluding statement or section related to information or explanation presented (CCSS.W.4.2.e). Informational and explanatory writing needs a CONCLUDING STATEMENT that wraps up the explanation. An effective conclusion does one or more of these: restates the main idea (not word-for-word, but synthesized—"Now you know that...", "As you can see..."), summarizes the key points briefly, provides a final thought about why the topic matters or what the reader should remember, and uses conclusion transition words (In conclusion, Finally, To sum up, Now you know, Therefore). The conclusion connects back to what was explained and gives the reader a sense of completion—it does NOT introduce major new information not mentioned in the body, and it's NOT just "The end" or "Done." Maya writes an explanation about exercise. The body includes benefits of exercise that were explained. The explanation includes a concluding statement that wraps up by summarizing benefits and connects back to the main idea about why exercise is important. Choice B is correct because Maya's concluding statement wraps up by summarizing the benefits of exercise and connects back to the main idea about why exercise matters. This gives the reader a sense of completion. Effective conclusions wrap up the explanation, don't introduce new major information, and connect back to the topic. Choice A is incorrect because it claims the conclusion introduces a new topic about vitamins and minerals when a good conclusion should connect to what was already explained, not introduce major new information. Students sometimes think conclusion should introduce new facts when it should connect to what's already explained. To help students write effective conclusions for informational/explanatory writing: Teach conclusion formula explicitly: "Restate + So What" or "Summary + Final Thought"; model with think-aloud: "I explained exercise benefits (stronger muscles, better heart health, improved mood). Now I'll wrap up by restating: 'Regular exercise improves our physical and mental health.' Final thought: 'Making exercise a habit helps us live healthier, happier lives.'" Show difference between introduction (This explanation is about...) and conclusion (Now you know that...); practice "Turn your introduction into a conclusion" by changing from future to past tense (will explain → explained/shows); post conclusion transition words: In conclusion, Finally, To sum up, Now you know, As you can see, Therefore, This shows that, In the end. Use "conclusion checklist": Does it restate main idea (not word-for-word)? Does it summarize key points? Does it provide final thought? Does it use transition word? Does it connect to topic? Does it avoid introducing major new information? Practice identifying strong vs weak conclusions with examples; provide sentence frames: "Now you know that [main idea]. This [why it matters]." or "In conclusion, [summary of key points]. [Final thought]." Give feedback on common errors: "This conclusion is too brief. Add a sentence restating your main idea." or "This introduces new information. Instead, wrap up by summarizing what you already explained." Watch for: students who introduce completely new facts in conclusion instead of wrapping up; students who confuse announcing the end with actually wrapping up ideas; students who think good conclusion must introduce new facts.

Question 19

1. First, a pulley is a simple machine that uses a rope and a wheel to work.
2. There are also levers and inclined planes that people use every single day.
3. To sum up, pulleys help lift heavy loads by changing the direction of force. (correct answer)
4. Another fun machine is the screw, which holds many things tightly together.

Explanation: A good conclusion for an explanation wraps things up. It uses a signal like "To sum up," and it restates the main idea in fresh words. The choice about pulleys helping lift heavy loads by changing the direction of force does exactly that, so it is the best ending. The sentence that begins with "First" sounds like a beginning, not an ending. The word "First" tells the reader you are just starting to explain, so it does not wrap anything up. The sentence about levers and inclined planes adds brand-new machines Carlos never explained. A conclusion should not bring in new topics; it should close the one you already wrote about. The sentence about the screw does the same thing. It introduces another new machine instead of summing up what Carlos said about pulleys. A strong ending sticks to the topic and reminds the reader of the main point.

Question 20

1. Add a final sentence that summarizes Carver’s impact and gives the reader a sense of closure. (correct answer)
2. Add a sentence that repeats his opening word-for-word so the ending matches the beginning exactly.
3. Add an interesting new fact about a different inventor who was never mentioned earlier in the writing.
4. Add a sentence that simply tells the reader the writing is now finished and there is nothing more.

Explanation: A strong conclusion wraps up what you explained and leaves the reader with a clear final thought. Adding a final sentence that summarizes Carver’s impact and gives closure does exactly this—it pulls the main ideas together, such as, "In conclusion, Carver's work with peanuts helped farmers and changed farming forever." Repeating your opening word-for-word is not a good conclusion. A conclusion should restate your main idea in fresh words and add a final thought, not copy the introduction exactly. Adding a brand-new fact about a different inventor pulls the reader away from Carver. A conclusion should wrap up what the body already explained, not introduce major new information. Adding a sentence that just announces the writing is finished does not summarize anything. Telling the reader you are done adds no ideas about Carver's contributions, so it leaves the explanation feeling unfinished. Only summarizing Carver’s impact and giving closure truly improves the conclusion.
