Step-by-step solution for: Comma Worksheet by Jeanieb worksheets library
Let's solve this comma worksheet step by step. The goal is to add commas where needed in each sentence. We'll go through each sentence, identify where commas are required based on grammar rules, and explain why.
---
1. After introductory phrases or clauses (e.g., "After the ball game").
2. Before coordinating conjunctions (and, but, or, nor, for, so, yet) when joining two independent clauses.
3. In compound sentences with multiple items (series).
4. Around direct quotations.
5. To separate appositives (extra information about a noun).
6. In addresses, dates, or names (not applicable here).
7. With interjections (e.g., "Wow!").
---
Now let’s go through each sentence:
---
✔ Corrected: *After the ball game, let’s go and get some dinner.*
- Why? "After the ball game" is an introductory phrase → needs a comma after it.
---
✔ Corrected: *Miranda, Tom, and Joe are playing ball later.*
- Why? This is a list of three people → use commas between items. Also, "and" before the last item (Oxford comma).
---
✔ No change needed.
- Why? "Janis Dixon" is a full name — no comma needed between first and last name unless it's part of a list or clarification. No additional punctuation needed.
---
✔ Corrected: *If you don’t finish your dinner, you won’t be going out later.*
- Why? "If you don’t finish..." is a dependent clause at the beginning → needs a comma before the main clause.
---
✔ Corrected: *After school, let’s go to the store.*
- Why? "After school" is an introductory phrase → comma after it.
---
✔ Corrected: *Owen said, “Meet me at the park later.”*
- Why? When someone says something, we place a comma after the verb ("said") before the quotation.
---
✔ Corrected: *Wow, that painting you did is amazing!*
- Why? "Wow" is an interjection → needs a comma after it.
---
✔ Corrected: *While my mom was cooking dinner, I did my homework.*
- Why? "While my mom was cooking..." is a dependent clause at the start → comma after it.
---
✔ Corrected: *I like red, green, blue, yellow, and orange.*
- Why? List of colors → commas between each. Oxford comma before "and".
---
✔ Corrected: *If we go to the theme park, I hope it doesn’t rain.*
- Why? Dependent clause at the beginning → comma after it.
---
✔ Corrected: *If you go fishing, remember to bring your bait.*
- Why? Dependent clause at the start → comma after it.
---
✔ Corrected: *After the party, let’s go over to the park.*
- Why? Introductory phrase → comma after it.
---
✔ Corrected: *“Wait for me, I can’t catch up to you,” said Jake.*
- Why?
- Inside the quote: "Wait for me" is a command, followed by another clause → comma needed.
- Then, the speaker tag comes after the quote → comma before "said Jake".
- So: Comma inside the quote, and comma before "said Jake".
---
✔ Corrected: *If you proofread your work, you’ll have fewer errors.*
- Why?
- "If you proofread..." is a dependent clause → comma after it.
- Also, "proof read" should be "proofread" (one word).
- "Less errors" → incorrect; "errors" is plural → use "fewer errors".
> Note: This sentence has both grammar and punctuation issues. But since the task is only about commas, we focus on:
> - Add comma after "work".
> - Fix "less" → "fewer" (for correctness, though not a comma issue).
But since the prompt says only add commas, we just correct:
→ *If you proofread your work, you’ll have less errors.*
But better: *If you proofread your work, you’ll have fewer errors.*
(We assume typo in "proof read" is acceptable if not asked to fix spelling.)
So final version: If you proofread your work, you’ll have fewer errors.
But for the comma only, we add one after "work".
---
✔ Corrected: *My dentist, Dr. Jones, is in that new building.*
- Why? "Dr. Jones" is an appositive (additional info about "dentist") → set off with commas on both sides.
---
1. After the ball game, let’s go and get some dinner.
2. Miranda, Tom, and Joe are playing ball later.
3. My friend Janis Dixon has 3 dogs. *(no change)*
4. If you don’t finish your dinner, you won’t be going out later.
5. After school, let’s go to the store.
6. Owen said, “Meet me at the park later.”
7. Wow, that painting you did is amazing!
8. While my mom was cooking dinner, I did my homework.
9. I like red, green, blue, yellow, and orange.
10. If we go to the theme park, I hope it doesn’t rain.
11. If you go fishing, remember to bring your bait.
12. After the party, let’s go over to the park.
13. “Wait for me, I can’t catch up to you,” said Jake.
14. If you proofread your work, you’ll have fewer errors. *(comma added, also fixed "proof read" and "less" → "fewer")*
15. My dentist, Dr. Jones, is in that new building.

The note says: *"Some sentences are missing more than one comma."*
Indeed, Sentence 13 has two commas needed:
- One inside the quote: "Wait for me, I can’t..."
- One before the speaker: ", said Jake"
And Sentence 15 has two commas (around the appositive).
So total commas added:
- 1: 1
- 2: 2
- 3: 0
- 4: 1
- 5: 1
- 6: 1
- 7: 1
- 8: 1
- 9: 4
- 10: 1
- 11: 1
- 12: 1
- 13: 2
- 14: 1
- 15: 2
✔ Total commas added: 15 sentences × average 1–2 commas = 15+
But we're not counting — just ensuring correctness.
