Question 1

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 2

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 3

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 4

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 5

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 6

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. 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 7

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 8

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 9

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 10

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 11

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 12

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 13

1. Yes, it restates her impact helping people escape and gives a final thought. (correct answer)
2. No, because it adds a new paragraph about a different leader not mentioned before.
3. Yes, because the conclusion should be just one word: "Finished."
4. No, because conclusions should only introduce the topic and list what will be explained.

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 Harriet Tubman. The body includes information about Tubman helping people escape. The explanation includes a conclusion that restates her impact and gives a final thought. Choice A is correct because Keisha's conclusion restates Harriet Tubman's impact helping people escape and gives a final thought. This effectively sums up by synthesizing the main idea about Tubman's important work and providing reflection on her significance. The conclusion connects back to what was explained and provides appropriate closure. Choice B is incorrect because it claims the conclusion adds information about a different leader, but the question states it focuses on Tubman's impact. Choice C incorrectly thinks conclusions should be just one word "Finished," which would be far too brief and wouldn't summarize anything. Choice D misunderstands conclusion purpose—conclusions wrap up what was explained, while introductions preview what will be explained. To help students write effective conclusions for informational/explanatory writing: Teach that biographical conclusions should capture the person's main impact or legacy; model: "I explained how Tubman led people to freedom. My conclusion will restate her impact: 'Tubman's brave actions helped hundreds escape slavery and inspired others to fight for freedom.'" Show how final thoughts add meaning: "This shows why we remember her today." Practice writing conclusions for historical figures that include both restatement and significance. Use formula for biographical conclusions: "[Person] [main achievement]. [Why this matters/legacy]." Create banks of final thought starters: "This shows...", "Today we remember...", "Her/his impact...". Watch for: students who think biographical conclusions need new facts about the person's childhood or death; students who write conclusions too focused on minor details rather than main impact; students who forget to include why the person matters or their lasting significance; students who confuse chronological endings ("Then she died") with conceptual conclusions (impact/legacy).

Question 14

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 15

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 16

1. A concluding statement that sums up evaporation, condensation, and precipitation. (correct answer)
2. Another body paragraph with more steps that were not explained yet.
3. A new topic sentence about hurricanes and tornadoes.
4. A concluding statement that asks a question and starts a new topic.

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." Sofia writes an explanation about the water cycle. The body includes the three main steps: evaporation, condensation, and precipitation. The explanation ends without any wrap-up after explaining these steps. Choice A is correct because Sofia should add a concluding statement that sums up evaporation, condensation, and precipitation to wrap up. For example: "In conclusion, the water cycle continuously moves water through evaporation, condensation, and precipitation, providing fresh water for all living things." This would restate the main idea and provide a final thought about why the water cycle matters. Choice B is incorrect because it suggests adding another body paragraph with more steps, but the conclusion should wrap up what's already explained, not add new content. Choice C incorrectly suggests a new topic sentence about hurricanes and tornadoes, which would start a completely different topic rather than conclude the water cycle explanation. Choice D suggests a conclusion that asks a question and starts a new topic, but conclusions should provide closure, not open new discussions. To help students write effective conclusions for informational/explanatory writing: Teach the difference between adding more body content (new facts) and wrapping up (summarizing what's explained); model conclusion writing: "I explained the three steps of the water cycle. Now I'll wrap up: 'These three processes work together to move water around Earth continuously.'" Use graphic organizers showing Body (facts) → Conclusion (wrap-up); provide transition words specifically for conclusions. Practice identifying what belongs in body vs conclusion; give sentence starters: "Now you understand how the water cycle..." or "These three steps show that..." Create a checklist: mentions all key points? connects them together? explains importance? Watch for: students who want to keep adding new information instead of wrapping up; students who think questions belong in conclusions; students who confuse continuing the explanation with concluding it; students who don't see the difference between body paragraphs and concluding statements.

Question 17

1. You can start growing your own garden this spring at home.
2. In conclusion, plants need water, sunlight, and soil to grow strong. (correct answer)
3. Plants are green and some plants can grow taller than tall houses.
4. This is my report about plants, and I really hope you liked it.

Explanation: A good conclusion for an explanation wraps things up by reminding the reader of the main idea. The sentence that begins with "In conclusion" does this best: it uses a closing transition word and restates the key point from the body—that plants need water, sunlight, and soil to grow. This gives the reader a clear sense that the explanation is finished. The sentence telling you to start a garden this spring adds a brand-new idea that was never explained in the report, so it does not sum up what Marcus wrote. The sentence about plants being green and growing taller than houses also brings in new facts instead of restating the main idea about what plants need. The sentence saying "This is my report about plants, and I really hope you liked it" is just a personal comment about the report itself; it does not summarize the information or remind readers what plants need. Only the sentence that restates the main point truly concludes the explanation.

Question 18

1. It is too vague, saying "That's all," without connecting back to how penguins survive. (correct answer)
2. It works well, saying "In conclusion," and reminding readers how penguins stay warm.
3. It is strong, saying "That's all," which briefly summarizes blubber and feathers.
4. It is confusing, saying "That's all," because it adds new facts about polar bears.

Explanation: A good conclusion wraps up your explanation by restating the main idea and connecting back to the topic. Chen ends with "That's all," which is too vague. Those words could end any writing about anything, so they don't remind readers how penguins survive with blubber and feathers. That is why the best answer says the conclusion is too vague and doesn't connect back to penguins. The choice claiming the conclusion works well is wrong because Chen never wrote "In conclusion" and never reminded readers how penguins stay warm—he just stopped. The choice calling it strong is wrong because "That's all" does not actually summarize blubber and feathers; it only signals the writing is over. The choice saying it is confusing is wrong because Chen didn't add new facts about polar bears; the real problem is that his ending is empty, not that it wanders off topic. When you finish an explanation, restate your main idea and add a final thought so readers remember what you taught them.

Question 19

1. Yes, it says "That's all," which tells readers the writing is finished but never sums up the desert facts.
2. No, it ends with one more fact and never restates what deserts are like for readers. (correct answer)
3. Yes, because it repeats the very first sentence exactly, which reminds readers where the explanation started.
4. No, because a good ending should list every single detail from the body so readers remember them all.

Explanation: A strong ending to an explanation wraps things up by pulling the main ideas together, like "Now you know deserts have extreme heat, little rain, and tough plants." It gives readers a sense of being finished. The best answer is that Amir's ending just adds one more fact and never restates what deserts are like, so it stops instead of closing. The choice about "That's all" is wrong because those words only announce that the writing is over—they don't actually sum up any desert facts, so readers get no wrap-up. The choice about repeating the first sentence exactly is wrong because a good conclusion synthesizes ideas in fresh words, not a word-for-word copy of the opening. The choice about listing every single detail is wrong because a conclusion summarizes the main points briefly instead of naming every fact from the body. To close well, Amir should add a sentence that ties his desert facts together, such as "As you can see, deserts are harsh but amazing places."

Question 20

1. Ending 1, because it ends with a short goodbye and lets readers know the writing is finished.
2. Ending 2, because it sums up the rain, layers, and animals with a final thought about rainforests. (correct answer)
3. Ending 1, because it brings in a helpful new idea about deserts to give readers even more to learn.
4. Ending 2, because it copies the very first sentence again so readers remember how the writing started.

Explanation: A good conclusion ties everything together. Ending 2 works best because it pulls back together the main points Keisha explained—the rain, the layers, and the animals—and adds a final thought. That gives readers a clear sense that the topic is complete. The choice that ends with a short goodbye is wrong because simply signaling that the writing is over does not remind readers of what was explained, so it leaves the topic feeling unfinished. The choice that brings in a new idea about deserts is wrong because a conclusion should wrap up what you already wrote, not open a brand-new topic. Adding deserts pulls readers away from rainforests instead of closing the explanation. The choice that copies the very first sentence again is wrong because repeating a sentence word-for-word is not the same as summarizing. A strong ending restates the ideas in a fresh way, not by copying. So the best ending is the one that briefly gathers the key points and finishes with a closing thought.
