Punctuation practice worksheet for students to correct sentence structure and punctuation marks.

Let’s go through each sentence one by one and fix the punctuation. We’ll add commas, periods, apostrophes, or other marks where needed to make the sentences clear and correct.

1. Our school play The Enchanted Forest will be performed next week

→ “The Enchanted Forest” is the name of the play, so it should be in quotation marks (or italics — but for this level, quotes are fine). Also, we need a period at the end.

✔ Corrected:
Our school play “The Enchanted Forest” will be performed next week.

2. The White House is located in Washington D.C

→ “Washington D.C.” needs a period after “D” and after “C” because it’s an abbreviation. Also, add a period at the end of the sentence.

✔ Corrected:
The White House is located in Washington D.C.

*(Note: Some style guides write it as “Washington, D.C.” with a comma — that’s also acceptable and often preferred. Let’s use the more common version with the comma.)*

✔ Even better:
The White House is located in Washington, D.C.

3. The Summer Olympics are held every four years

→ This sentence is almost perfect! Just missing a period at the end.

✔ Corrected:
The Summer Olympics are held every four years.

4. Hi Alex Where are you going after school today

→ This is two parts: a greeting (“Hi Alex”) and a question (“Where are you going...”). We need a comma after “Hi Alex”, and a question mark at the end.

✔ Corrected:
Hi Alex, where are you going after school today?

*(Also note: “where” doesn’t need to be capitalized unless it starts a new sentence — here it’s part of the same sentence after the comma.)*

5. We went to the beach and we built sandcastles

→ This is a compound sentence (two independent clauses joined by “and”). It’s okay without a comma if both parts are short — but adding a comma before “and” makes it clearer. Also, add a period at the end.

✔ Corrected:
We went to the beach, and we built sandcastles.

*(Optional: You could also say “We went to the beach and built sandcastles” to avoid repetition — but since the original says “we built,” we’ll keep it and just add punctuation.)*

6. The cat was sleeping she woke up when we entered

→ This is a run-on sentence. Two complete thoughts stuck together. We can fix it by making two sentences, or using a conjunction like “but” or “and”. Since the second part contrasts with the first (“sleeping” vs “woke up”), “but” works well. Add a period at the end.

✔ Corrected:
The cat was sleeping, but she woke up when we entered.

*(Alternatively: “The cat was sleeping. She woke up when we entered.” — also correct. But using “but” shows the relationship between the ideas.)*
