- Which sentence places the comma correctly after the introductory phrase?
Answer: After school, we finished our science project in the library.
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.
- Which revision correctly uses a comma after the introductory word?
Answer: Finally, Yuki found her missing notebook under the couch.
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.
- Which sentence correctly uses a comma after the introductory element?
Answer: Because Amir studied, he felt ready for the spelling test.
An introductory element is a group of words that comes before the main part of the sentence. Here the introductory element is "Because Amir studied," so the comma belongs right after "studied" and before the main part, "he felt ready for the spelling test." That is why placing the comma after "studied" is correct. Putting the comma after "felt" wrongly breaks up the main part of the sentence instead of setting off the introductory element. Putting the comma after "Amir" splits up the introductory element itself, which should stay together. Putting the comma after "he" separates the subject from its verb inside the main part, so it does not mark the introductory element either. Only the comma after "studied" cleanly separates the introductory element from the rest of the sentence.
- Which sentence places the comma correctly after the introductory word?
Answer: However, we decided to keep practicing for the basketball game.
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.
- Read the sentence. Where does the comma belong to separate the introductory clause from the main clause?
Answer: If you finish your math early, you may read a book quietly.
The sentence starts with an introductory clause: 'If you finish your math early.' This clause tells the condition for the main idea, so a comma should go right after it, before the main clause 'you may read a book quietly.' The best answer places the comma exactly there. One choice puts the comma in the middle of the introductory clause, after 'your math,' which breaks up the condition and cuts the idea in half. Another choice puts the comma after 'you may,' which is inside the main clause and does not separate the introduction from the main idea at all. The last choice has no comma anywhere, so nothing shows where the introductory clause ends and the main clause begins, making the sentence harder to read. To find the right spot, read until you reach the end of the 'If...' part—that is where the introductory clause finishes—and put the comma there before the rest of the sentence.
- Which sentence correctly uses a comma after the introductory clause?
Answer: When the bell rang, students lined up quietly in the hallway.
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.
- Which sentence correctly places a comma after the introductory phrase?
Answer: Before dinner, Marcus washed his hands and set the table.
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 correct sentence puts the comma after "Before dinner," which is the whole introductory phrase. One sentence leaves out the comma completely, so the introductory phrase is not set off at all. Another sentence puts the comma after "hands," which breaks up the two things Marcus did instead of following the introductory phrase. The last sentence puts the comma after "Before," splitting up the phrase "Before dinner" in the middle, so the comma is in the wrong spot. Only the first sentence marks the end of the whole introductory phrase correctly.
- Read the sentence. Which revision correctly uses a comma after the introductory word at the beginning?
Answer: However, we still finished the science project on time.
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.
- Which sentence correctly places a comma after the introductory clause?
Answer: If we finish early, we can play a quick game outside.
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.
- Which sentence correctly adds a comma to separate the introductory phrase from the main part of the sentence?
Answer: Near the playground, Jamal found his missing water bottle.
The introductory phrase "Near the playground" should be set off with a comma right after it: "Near the playground, Jamal found his missing water bottle." Choice A is correct. Choice B puts the comma after "Near," Choice C after "Jamal," and Choice D after "found," so none separates the introductory phrase correctly.
- Read the sentence. Which revision correctly uses a comma to separate the introductory element?
Answer: In the morning, we feed our dog before we eat breakfast.
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."
- Read the sentence. Where should a comma be placed to separate the introductory phrase at the beginning?
Answer: Before dinner, Chen washed his hands and set the table.
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.
- Read the sentence. Add a comma to separate the introductory clause from the rest.
Answer: When the bell rang, Jamal lined up with his class.
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.
- Which sentence places the comma correctly between the introductory clause and the main clause?
Answer: If you finish your homework, you can play outside for a while.
When a sentence begins with an introductory clause like "If you finish your homework," you put a comma right after that clause and before the main clause. The correct sentence places the comma after "homework," clearly separating the introductory clause from "you can play outside for a while." The choice with no comma at all never marks the break between the two clauses, so the reader can't tell where the introductory part ends. Another choice drops the comma in the middle of the main clause, after "can," which splits "you can play" instead of separating the clauses. The last choice puts the comma near the end, before "for a while," which only breaks up the main clause and still leaves the introductory clause unseparated. Only the comma placed after "homework" does the job the introductory element needs.
- Read the sentence. Choose the version that correctly uses a comma to separate the introductory phrase from the main clause.
Answer: Before dinner, Chen fed the dog and set the table.
The sentence begins with the introductory phrase 'Before dinner,' which tells when the action happens. A comma belongs right after this phrase to separate it from the main clause, so 'Before dinner, Chen fed the dog and set the table.' is correct. The version reading 'After dinner Chen, fed the dog' puts the comma after the subject 'Chen,' which wrongly splits the subject from its verb. The version reading 'Before, dinner Chen' breaks the phrase 'Before dinner' in half, so the comma lands in the middle of the introductory element instead of after it. The version reading 'fed the dog, and set the table' places the comma before 'and,' but 'set the table' is not a complete sentence, so no comma is needed there—and the introductory phrase still has no comma. Only the correct choice puts the comma exactly where the introductory phrase ends and the main clause begins.
- Which sentence places the comma correctly to separate the introductory clause?
Answer: When the bell rang, the class lined up quietly for lunch.
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.
- Which sentence correctly adds a comma to separate the introductory word from the rest?
Answer: Suddenly, the lights went out during our class movie.
The introductory word "Suddenly" should be set off with a comma right after it: "Suddenly, the lights went out during our class movie." Choice C is correct. Choice A puts the comma after "lights," Choice B has no comma, and Choice D adds an extra comma after "lights," so none is punctuated correctly.
- Read the sentence. Where does the comma belong after the introductory clause at the beginning?
Answer: If you finish your homework, you can play a board game.
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.
- Which sentence correctly places a comma after the introductory word?
Answer: Suddenly, the lights flickered during the class movie.
When a sentence begins with an introductory word like "Suddenly," you put a comma right after that word and before the rest of the sentence. The choice that reads "Suddenly, the lights flickered during the class movie" does exactly that, so it is correct. One choice leaves out the comma entirely, so the introductory word is never set off. Another puts the comma before "during," which breaks up the action instead of marking the opening word. The last choice drops the comma after "during," splitting a phrase in the middle rather than following the introductory word. Only the comma placed right after "Suddenly" matches the rule.
- Read the sentence. Which sentence correctly uses a comma after an introductory clause at the beginning?
Answer: Because it was windy, Jamal flew his kite near the beach.
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.
