Question 1
Which sentence correctly places a comma after the introductory clause?
- If we finish early we can, play a quick game outside.
- If we finish early we can play, a quick game outside.
- If we finish early, we can play a quick game outside. (correct answer)
- If we finish, early we can play a quick game outside.
Explanation: An introductory clause is a group of words that sets up the main sentence, and it needs a comma right at the point where it ends. The introductory clause here is "If we finish early," so the comma belongs after the word "early." The correct sentence places the comma there, before the main part "we can play a quick game outside." One sentence puts the comma after "can," which splits the verb from what comes next and does not mark the end of the introductory clause. Another puts the comma after "play," cutting off the verb from its object instead of following the clause. The last sentence puts the comma after "finish," breaking up "finish early" in the middle of the introductory clause. Only the sentence with the comma after "early" marks the true end of the introductory part.
Question 2
Read the sentence. Where does the comma belong after the introductory clause at the beginning?
- If, you finish your homework you can play a board game.
- If you finish your homework you can play a board game.
- If you finish your homework, you can play a board game. (correct answer)
- If you finish your homework you, can play a board game.
Explanation: This question tests CCSS.L.5.2.b: using a comma to separate an introductory element from the rest of the sentence. An introductory element comes at the beginning of a sentence and provides context about when, where, why, how, or under what conditions the main action occurs. A comma is placed immediately after the introductory element to separate it from the main clause. Types include: single words (Yesterday, However), prepositional phrases (In the morning, After school), and dependent clauses (When it rains, If you finish). This sentence begins with a dependent clause: 'If you finish your homework'. This provides condition context for the main sentence. The main clause begins with 'you can play'. Choice A is correct because it places the comma immediately after the introductory element 'If you finish your homework,', separating it from the main clause. The comma signals the shift from introductory context to the main idea, making the sentence structure clear: 'If you finish your homework, you can play a board game.' Choice D represents missing comma error. This error makes sentence harder to read and obscures where introduction ends. Students make this error when they don't recognize introductory elements, especially dependent clauses. To help students: Teach them to identify introductory elements by asking 'What comes before the main idea?' or 'What gives context for the sentence?' Practice underlining or bracketing the introductory element, then placing comma after it before the main clause. Create formula: [Introductory element], [main clause]. Common introductory patterns: single transition words (However, Therefore), time/place words (Yesterday, Outside), prepositional phrases starting sentences (In the morning, After school, Under the tree), dependent clauses (When..., If..., Because..., Although...). Have students identify the subject and verb of main clause - comma goes before these. Remember: even SHORT introductory phrases should have comma in 5th grade writing.
Question 3
Read the sentence. Where should a comma be placed to separate the introductory phrase at the beginning?
- Before dinner, Chen washed his hands and set the table. (correct answer)
- Before, dinner Chen washed his hands and set the table.
- Before dinner Chen washed his hands, and set the table.
- Before dinner Chen washed his hands and set the table,
Explanation: This sentence starts with the introductory phrase 'Before dinner,' which tells when the action happens. A comma should go right after the whole introductory phrase to separate it from the main part of the sentence: 'Before dinner, Chen washed his hands and set the table.' The choice that places the comma after 'Before' is wrong because it splits the phrase apart in the middle, leaving 'dinner Chen' stuck together. The choice with a comma after 'his hands' is wrong because it puts the comma inside the main sentence, between two things Chen did, instead of after the introductory phrase. The choice with a comma at the very end is wrong because a comma cannot separate an introductory phrase when it sits after the whole sentence—the introductory phrase comes first, so the comma belongs right after it. To find the right spot, read the sentence, decide where the introductory phrase ends, and place the comma there before the main idea begins.
Question 4
Which sentence places the comma correctly after the introductory word?
- However we, decided to keep practicing for the basketball game.
- However, we decided to keep practicing for the basketball game. (correct answer)
- However we decided, to keep practicing for the basketball game.
- However we decided to, keep practicing for the basketball game.
Explanation: When a sentence begins with an introductory word like "However," you put a comma right after that word to separate it from the rest of the sentence. The correct choice places the comma directly after "However," which is exactly the right spot. The choice with the comma after "we" is wrong because "we" is the subject and should not be cut off from its verb. The choice with the comma after "decided" is wrong because it breaks up the verb from what comes next. The choice with the comma after "to" is wrong because it splits "to keep," which belong together. Only the comma placed right after the introductory word "However" is correct.
Question 5
Read the sentence. Add a comma to separate the introductory element from the rest of the sentence.
- In the library, Maya found a book about planets. (correct answer)
- In, the library Maya found a book about planets.
- In the library Maya, found a book about planets.
- In the library Maya found, a book about planets.
Explanation: This question tests CCSS.L.5.2.b: using a comma to separate an introductory element from the rest of the sentence. An introductory element comes at the beginning of a sentence and provides context about when, where, why, how, or under what conditions the main action occurs. A comma is placed immediately after the introductory element to separate it from the main clause. Types include: single words (Yesterday, However), prepositional phrases (In the morning, After school), and dependent clauses (When it rains, If you finish). This sentence begins with a prepositional phrase: 'In the library'. This provides location context for the main sentence. The main clause begins with 'Maya found'. Choice A is correct because it places the comma immediately after the introductory element 'In the library,', separating it from the main clause. The comma signals the shift from introductory context to the main idea, making the sentence structure clear: 'In the library, Maya found a book about planets.' Choice B represents comma in wrong place error. This error breaks the prepositional phrase incorrectly by placing comma after 'In' instead of after the complete phrase. Students make this error when they confuse with other comma uses. To help students: Teach them to identify introductory elements by asking 'What comes before the main idea?' or 'What gives context for the sentence?' Practice underlining or bracketing the introductory element, then placing comma after it before the main clause. Create formula: [Introductory element], [main clause]. Common introductory patterns: single transition words (However, Therefore), time/place words (Yesterday, Outside), prepositional phrases starting sentences (In the morning, After school, Under the tree). Remember: even SHORT introductory phrases should have comma in 5th grade writing.
Question 6
Read the sentence. Which revision correctly uses a comma to separate the introductory phrase?
- After school, we practiced soccer in the field. (correct answer)
- After school we, practiced soccer in the field.
- After school we practiced, soccer in the field.
- After, school we practiced soccer in the field.
Explanation: This question tests CCSS.L.5.2.b: using a comma to separate an introductory element from the rest of the sentence. An introductory element comes at the beginning of a sentence and provides context about when, where, why, how, or under what conditions the main action occurs. A comma is placed immediately after the introductory element to separate it from the main clause. Types include: single words (Yesterday, However), prepositional phrases (In the morning, After school), and dependent clauses (When it rains, If you finish). This sentence begins with a prepositional phrase: 'After school'. This provides time context for the main sentence. The main clause begins with 'we practiced'. Choice B is correct because it places the comma immediately after the introductory element 'After school,', separating it from the main clause. The comma signals the shift from introductory context to the main idea, making the sentence structure clear: 'After school, we practiced soccer in the field.' Choice A represents comma in wrong place error. This error breaks the subject-verb connection by placing comma between 'we' and 'practiced', which disrupts the main clause. Students make this error when they place comma by feel rather than rule. To help students: Teach them to identify introductory elements by asking 'What comes before the main idea?' or 'What gives context for the sentence?' Practice underlining or bracketing the introductory element, then placing comma after it before the main clause. Create formula: [Introductory element], [main clause]. Common introductory patterns: single transition words (However, Therefore), time/place words (Yesterday, Outside), prepositional phrases starting sentences (In the morning, After school, Under the tree), dependent clauses (When..., If..., Because..., Although...). Have students identify the subject and verb of main clause - comma goes before these.
Question 7
Read the sentence. Where should a comma be placed to separate the introductory word?
- However we decided to practice basketball inside the gym.
- However, we decided to practice basketball inside the gym. (correct answer)
- However, we decided to practice basketball, inside the gym.
- However we decided, to practice basketball inside the gym.
Explanation: The word 'However' at the start of the sentence is an introductory word. It gives context before the main idea, so it needs a comma right after it to separate it from the rest of the sentence. The best answer places the comma immediately after 'However,' and then continues with the main clause: 'we decided to practice basketball inside the gym.' The choice with no comma at all leaves the introductory word running into the main clause, so the reader can't tell where the introduction ends. The choice that adds a comma before 'inside the gym' does put a comma after 'However,' but it also breaks up 'practice basketball inside the gym,' where no comma belongs. The choice with a comma after 'decided' splits the verb 'decided' from what the group decided to do, and it also skips the needed comma after the introductory word. Only one choice puts a single comma exactly where the introductory word ends and the main idea begins.
Question 8
Which sentence correctly uses a comma after the introductory clause?
- When the bell rang students lined up quietly in the hallway.
- When the bell rang, students lined up quietly in the hallway. (correct answer)
- When the bell, rang students lined up quietly in the hallway.
- When the bell rang students, lined up quietly in the hallway.
Explanation: The introductory clause "When the bell rang" should be followed by a comma before the main clause. Choice B places the comma after "rang," so it is correct. Choice A has no comma, Choice C puts it after "bell," and Choice D puts it after "students," so none separates the two clauses correctly.
Question 9
Which revision correctly uses a comma after the introductory word?
- Finally Yuki found her missing notebook under the couch.
- Finally, Yuki found her missing notebook under the couch. (correct answer)
- Finally Yuki found, her missing notebook under the couch.
- Finally, Yuki, found her missing notebook under the couch.
Explanation: The introductory word "Finally" should be followed by a comma before the rest of the sentence. Choice B places the comma right after "Finally," so it is correct. Choice A has no comma, Choice C puts it after "found," and Choice D adds an extra comma after "Yuki," so none punctuates the introductory word correctly.
Question 10
Read the sentence. Which revision correctly uses a comma to separate the introductory element?
- In, the morning we feed our dog before we eat breakfast.
- In the morning we feed our dog before we eat breakfast.
- In the morning we, feed our dog before we eat breakfast.
- In the morning, we feed our dog before we eat breakfast. (correct answer)
Explanation: When a sentence begins with an introductory element—a group of words that sets the scene before the main action—you use a comma to separate it from the rest of the sentence. Think of the comma as a little pause that tells your reader, "Okay, the setup is done, now here comes the main idea!"
To find where the comma goes, first spot the introductory part. In this sentence, "In the morning" tells us when something happens. That whole phrase is your introduction, so the comma belongs right after it: "In the morning, we feed our dog before we eat breakfast." Now the pause lands in exactly the right spot.
Try this: read the sentence out loud and listen for the natural pause after the opening phrase. That's usually where your comma goes! Practice with a sentence like "After school, I ride my bike."
Question 11
Which revision correctly uses a comma after the introductory element?
- In the morning, Maya feeds the dog before she eats breakfast. (correct answer)
- In the morning Maya feeds the dog, before she eats breakfast.
- In the morning Maya, feeds the dog before she eats breakfast.
- In the morning Maya feeds the dog before she eats breakfast.
Explanation: An introductory element is a word or phrase that comes before the main part of the sentence, and it should be followed by a comma. Here the introductory phrase is "In the morning," so the comma belongs right after "morning"—that is what the correct choice does. Placing the comma after "the dog" puts it in the middle of the sentence, not after the introductory phrase, so it does not fix the sentence. Placing the comma after "Maya" wrongly separates the subject from its verb "feeds" and still leaves the introductory phrase without a comma. Leaving out the comma entirely means the introductory phrase is not set off at all. Only the version with the comma directly after "morning" correctly punctuates the introductory element.
Question 12
Which sentence places the comma correctly to separate the introductory clause?
- When the bell rang the class, lined up quietly for lunch.
- When the bell rang, the class lined up quietly for lunch. (correct answer)
- When the bell rang the class lined up, quietly for lunch.
- When the bell rang the class lined up quietly, for lunch.
Explanation: An introductory clause tells when or how the main action happens, and it needs a comma right after it before the main clause begins. Here the introductory clause is "When the bell rang," so the comma belongs after "rang." The correct sentence places the comma there: "When the bell rang, the class lined up quietly for lunch." One choice puts the comma after "class," splitting the subject from its verb instead of closing the introductory clause. Another puts the comma after "up," breaking up the main clause and its describing word. The last choice puts the comma after "quietly," separating an ending phrase that does not need a comma at all. Only the comma after "rang" marks where the introductory clause ends and the main idea starts.
Question 13
Which revision correctly uses a comma to separate the introductory phrase in this sentence: Walking carefully Amir carried the glass of water to the sink?
- Walking carefully Amir, carried the glass, of water to the sink.
- Walking, carefully Amir carried the glass of water to the sink.
- Walking carefully, Amir carried the glass of water to the sink. (correct answer)
- Walking carefully Amir, carried the glass of water to the sink.
Explanation: The introductory phrase here is "Walking carefully," which describes how Amir moved. An introductory phrase should be followed by a comma right before the main part of the sentence begins. The correct sentence places one comma after "carefully" and then continues with "Amir carried the glass of water to the sink." The choice that puts a comma after just "Walking" splits the introductory phrase in half, so the comma lands in the wrong spot. Another choice puts the comma after "Amir," which separates the subject from the verb instead of closing the introductory phrase. The last choice adds a comma after "Amir" and an extra comma inside "the glass of water," so it uses two commas incorrectly and still never closes the introductory phrase. Only placing the single comma right after "carefully" correctly separates the introduction from the rest of the sentence.
Question 14
Read the sentence. How should the sentence be punctuated to separate the introductory phrase?
- During lunch Sofia traded her apple, for a granola bar.
- During lunch Sofia, traded her apple for a granola bar.
- During lunch Sofia traded her apple for a granola bar.
- During lunch, Sofia traded her apple for a granola bar. (correct answer)
Explanation: The sentence begins with the introductory phrase 'During lunch,' which tells when the action happens. A comma belongs right after that phrase and before the main part of the sentence, so the correct answer places the comma after 'During lunch.' This shows the reader where the introduction ends and the main idea begins. The choice with a comma after 'apple' breaks up the main part of the sentence for no reason, and it does not separate the introductory phrase at all. The choice with a comma after 'Sofia' wrongly splits the subject from its verb, 'traded,' instead of marking off the introduction. The choice with no comma at all leaves the introductory phrase and the main clause running together, so nothing is separated. Remember: even a short introductory phrase like 'During lunch' needs a comma after it before the sentence continues.
Question 15
Read the sentence. Add a comma to separate the introductory clause from the rest.
- When the bell rang, Jamal lined up with his class. (correct answer)
- When the bell rang Jamal lined up with his class.
- When the bell, rang Jamal lined up with his class.
- When the bell rang Jamal, lined up with his class.
Explanation: This question tests CCSS.L.5.2.b: using a comma to separate an introductory element from the rest of the sentence. An introductory element comes at the beginning of a sentence and provides context about when, where, why, how, or under what conditions the main action occurs. A comma is placed immediately after the introductory element to separate it from the main clause. Types include: single words (Yesterday, However), prepositional phrases (In the morning, After school), and dependent clauses (When it rains, If you finish). This sentence begins with a dependent clause: 'When the bell rang'. This provides time/condition context for the main sentence. The main clause begins with 'Jamal lined up'. Choice A is correct because it places the comma immediately after the introductory element 'When the bell rang,', separating it from the main clause. The comma signals the shift from introductory context to the main idea, making the sentence structure clear: 'When the bell rang, Jamal lined up with his class.' Choice B represents a missing comma error. This error makes it unclear where the introductory clause ends and the main clause begins. Students make this error when they don't recognize dependent clauses as introductory elements needing commas. To help students: Teach them to identify introductory elements by asking 'What comes before the main idea?' or 'What gives context for the sentence?' Practice underlining or bracketing the introductory element, then placing comma after it before the main clause. Create formula: [Introductory element], [main clause]. Common introductory patterns: single transition words (However, Therefore), time/place words (Yesterday, Outside), prepositional phrases starting sentences (In the morning, After school, Under the tree), dependent clauses (When..., If..., Because..., Although...). Have students identify the subject and verb of main clause - comma goes before these.
Question 16
Read the sentence. Which revision correctly uses a comma after the introductory phrase?
- In the morning we pack our backpacks, before leaving.
- In the morning we pack, our backpacks before leaving.
- In the morning, we pack our backpacks before leaving. (correct answer)
- In the morning we pack our backpacks before, leaving.
Explanation: This sentence starts with the introductory phrase 'In the morning,' which tells you when the action happens. A comma belongs right after that phrase to separate it from the main part of the sentence: 'In the morning, we pack our backpacks before leaving.' That is why the choice with the comma after 'morning' is correct. One choice puts the comma before 'leaving,' which just breaks up the ending and does not mark the introductory phrase at all. Another puts the comma after 'pack,' splitting the main action from what is being packed. A third puts the comma after 'backpacks,' cutting off 'before leaving' for no reason. In every wrong choice, the comma lands somewhere in the middle of the main clause instead of at the end of the introductory phrase. Remember the pattern: [introductory phrase], [main clause]. Ask yourself, 'What part gives the time, place, or condition before the main idea?' Bracket that part, then place the comma right after it and before the main clause.
Question 17
Read the sentence. Which revision correctly uses a comma after the introductory word at the beginning?
- However, we still finished, the science project on time.
- However, we still finished the science project on time. (correct answer)
- However we still finished the science project on time.
- However we still finished, the science project on time.
Explanation: This question tests CCSS.L.5.2.b: using a comma to separate an introductory element from the rest of the sentence. An introductory element comes at the beginning of a sentence and provides context about when, where, why, how, or under what conditions the main action occurs. A comma is placed immediately after the introductory element to separate it from the main clause. Types include: single words (Yesterday, However), prepositional phrases (In the morning, After school), and dependent clauses (When it rains, If you finish). This sentence begins with an introductory word: 'However'. This provides transition/contrast context for the main sentence. The main clause begins with 'we still finished'. Choice B is correct because it places the comma immediately after the introductory element 'However,', separating it from the main clause. The comma signals the shift from introductory context to the main idea, making the sentence structure clear: 'However, we still finished the science project on time.' Choice D represents multiple commas error. This error adds an unnecessary comma within the main clause, breaking sentence incorrectly. Students make this error when they confuse introductory commas with series commas. To help students: Teach them to identify introductory elements by asking 'What comes before the main idea?' or 'What gives context for the sentence?' Practice underlining or bracketing the introductory element, then placing comma after it before the main clause. Create formula: [Introductory element], [main clause]. Common introductory patterns: single transition words (However, Therefore), time/place words (Yesterday, Outside). Use hand motion: introduction (hand up), comma (pause), main clause (hand down). Watch for: omitting comma entirely (most common), placing comma within introductory element instead of after it.
Question 18
Which sentence places the comma correctly after the introductory phrase?
- After, school we finished our science project in the library.
- After school we finished, our science project in the library.
- After school we, finished our science project in the library.
- After school, we finished our science project in the library. (correct answer)
Explanation: An introductory phrase tells when or where something happens, and it needs a comma right after it, before the main part of the sentence. The introductory phrase here is "After school," so the comma belongs right after the word "school" and before "we": After school, we finished our science project in the library. One choice breaks up the phrase by putting the comma between "After" and "school," which splits a phrase that should stay together. Another choice puts the comma after "we," separating the subject from the beginning of the sentence for no reason. A third choice puts the comma after "finished," which cuts the verb off from what the students finished. Only placing the comma after the full introductory phrase "After school" is correct.
Question 19
Read the sentence. Which sentence correctly uses a comma after an introductory clause at the beginning?
- Because it was windy, Jamal flew his kite near the beach. (correct answer)
- Because, it was windy Jamal flew his kite near the beach.
- Because it was windy Jamal, flew his kite near the beach.
- Because it was windy Jamal flew, his kite near the beach.
Explanation: This question tests CCSS.L.5.2.b: using a comma to separate an introductory element from the rest of the sentence. An introductory element comes at the beginning of a sentence and provides context about when, where, why, how, or under what conditions the main action occurs. A comma is placed immediately after the introductory element to separate it from the main clause. Types include: single words (Yesterday, However), prepositional phrases (In the morning, After school), and dependent clauses (When it rains, If you finish). This sentence begins with a dependent clause: 'Because it was windy'. This provides cause/reason context for the main sentence. The main clause begins with 'Jamal flew'. Choice A is correct because it places the comma immediately after the introductory element 'Because it was windy,', separating it from the main clause. The comma signals the shift from introductory context to the main idea, making the sentence structure clear: 'Because it was windy, Jamal flew his kite near the beach.' Choice B represents comma in wrong place error. This error breaks the dependent clause incorrectly by placing comma after 'Because' instead of after the complete introductory clause. Students make this error when they don't recognize complete introductory elements. To help students: Teach them to identify introductory elements by asking 'What comes before the main idea?' or 'What gives context for the sentence?' Practice underlining or bracketing the introductory element, then placing comma after it before the main clause. Create formula: [Introductory element], [main clause]. Common introductory patterns: dependent clauses (When..., If..., Because..., Although...). Watch for: placing comma within introductory element instead of after it.
Question 20
Read the sentence. Which sentence correctly uses a comma after an introductory element?
- Carefully Chen, carried the glass jar to the counter.
- Carefully Chen carried the glass jar to the counter.
- , Carefully Chen carried the glass jar to the counter.
- Carefully, Chen carried the glass jar to the counter. (correct answer)
Explanation: An introductory element is a word or group of words that begins a sentence and gives us extra information before we get to the main idea. When you use one, you set it off with a comma to show where the introduction ends and the rest of the sentence begins.
Here's how to find the right spot. First, look at the beginning of the sentence for that introductory word: "Carefully." Next, ask yourself where the introduction stops and the main part starts. The main part is "Chen carried the glass jar to the counter." So the comma belongs right after "Carefully."
That's why "Carefully, Chen carried the glass jar to the counter." is correct—the comma sits neatly between the introduction and the rest.
Try this: write a sentence starting with a word like "Quietly" or "Suddenly," then drop a comma right after it before the rest of your sentence!
