Punctuation Worksheets Fix the Sentences Grammar Practice, 3rd Grade - Free Printable

Let's go through each sentence and correct the punctuation. The goal is to add proper punctuation (like commas, quotation marks, apostrophes, periods, question marks, etc.) so that each sentence is grammatically correct and clear.

---

1. The books cover was colorful and eye-catching

- Error: "books" should be possessive — it's "the book's cover".
- Correction: Add an apostrophe to show possession.
- ✔ Corrected: *The book's cover was colorful and eye-catching.*

2. I want to visit the space museum said Tim dreamily

- Error: This is a direct quote. The speaker tag ("said Tim dreamily") should follow the quote, and the quote needs quotation marks and proper punctuation.
- Correction: Put the quote in quotation marks, end with a period inside the quotes, then add the speaker tag after a comma.
- ✔ Corrected: *"I want to visit the space museum," said Tim dreamily.*

3. The butterfllys wings were vibrant and delicate

- Error: "butterfllys" is misspelled — it should be "butterfly's" (possessive form).
- Correction: Add apostrophe for possession.
- ✔ Corrected: *The butterfly's wings were vibrant and delicate.*

4. I can't believe it's snowing exclaimed Lily

- Error: Direct speech without quotation marks; missing punctuation.
- Correction: Use quotation marks around the exclamation, and place the exclamation mark inside the quotes. Then add a comma before the speaker tag.
- ✔ Corrected: *"I can't believe it's snowing!" exclaimed Lily.*

5. Let's plant flowers in the garden suggested Grandma

- Error: Direct suggestion without quotation marks.
- Correction: Place the suggestion in quotation marks, use a comma before the speaker tag.
- ✔ Corrected: *"Let's plant flowers in the garden," suggested Grandma.*

6. How was your day Mom inquired with a smile

- Error: Missing quotation marks and punctuation in a question.
- Correction: The question must be enclosed in quotation marks, and since it's a question, it ends with a question mark. Also, need a comma before the speaker tag.
- ✔ Corrected: *"How was your day, Mom?" inquired with a smile.*

Wait! There's another issue: "inquired with a smile" is not correctly placed. It should be attached to the speaker — but "Mom" is the one being addressed, not the one speaking. So we need to rephrase slightly.

Actually, the original sentence says:
"How was your day Mom inquired with a smile"
This implies that Mom is the one asking the question.

So the corrected version should be:

✔ "How was your day, Mom?" she inquired with a smile.

But wait — the original doesn’t have "she". That’s a problem. We need to assume the subject of “inquired” is implied or corrected.

Looking back:
"How was your day Mom inquired with a smile"
This seems to mean: Mom asked the question, so the speaker is Mom.

But the sentence structure is incorrect because “Mom” is part of the question, not the speaker.

Better interpretation:
It should be: *"How was your day, Mom?"* — and this is something someone else is asking.

But the sentence says "Mom inquired", meaning Mom is the one asking.

So likely, the intended meaning is:
Someone is asking Mom, "How was your day?" and the speaker says it with a smile.

But the sentence says:
"How was your day Mom inquired with a smile"

That would mean: Mom is the one saying it — so the sentence should be:

👉 *"How was your day, Mom?" inquired [someone] with a smile.*

But there's no subject for "inquired" — only "Mom".

Ah! Here's the confusion.

The sentence is:
"How was your day Mom inquired with a smile"

This could be interpreted as:
- "How was your day?" Mom inquired with a smile.

So Mom is the one speaking.

Therefore, the correct version is:

✔ "How was your day?" Mom inquired with a smile.

Yes — now it makes sense.

We put the question in quotation marks, end with a question mark, then add the speaker tag with a comma.
