Writing compound sentences worksheets | Worsheets library - Free Printable

Of course! Let’s solve this “Compound Sentences” worksheet step by step.

The goal is to combine each pair of sentences using a comma and the word in brackets. The words given are: *but, and, or, so, yet*. These are coordinating conjunctions that join two independent clauses (complete thoughts).

Here’s how we do it:
1. Take the first sentence.
2. Add a comma.
3. Add the conjunction from the bracket.
4. Add the second sentence.

Let’s go through each one:

---

1. She did not go to the park. It was too late in the evening. (but)
→ She did not go to the park, but it was too late in the evening.

*(“But” shows contrast — she didn’t go because it was late.)*

---

2. They arrived early at the show. They had great seats. (and)
→ They arrived early at the show, and they had great seats.

*(“And” adds information — arriving early led to good seats.)*

---

3. My family has never been to Washington. We have seen Boston. (but)
→ My family has never been to Washington, but we have seen Boston.

*(“But” contrasts two facts — haven’t been to one place, but have been to another.)*

---

4. I really like chocolate cake. I am too full for dessert. (but)
→ I really like chocolate cake, but I am too full for dessert.

*(“But” shows contradiction — liking something vs. being unable to eat it.)*

---

5. We could start the movie now. We could wait for Julia to arrive. (or)
→ We could start the movie now, or we could wait for Julia to arrive.

*(“Or” presents two choices.)*

---

6. I am allergic to cats. I love to pet them. (yet)
→ I am allergic to cats, yet I love to pet them.

*(“Yet” shows surprise or contrast — despite being allergic, I still love them.)*

---

7. Mark finished his homework. We can go play outside. (so)
→ Mark finished his homework, so we can go play outside.

*(“So” shows cause and effect — finishing homework allows playing outside.)*

---

8. You cannot go outside. It started to rain. (for)
Wait — the bracket says (for), but “for” is not typically used as a coordinating conjunction in modern elementary grammar like this. In older usage, “for” can mean “because,” but most curricula use “so” or “because.” Since the worksheet lists “for” here, we’ll follow the instruction.

→ You cannot go outside, for it started to rain.

*(“For” = because — explaining the reason.)*

> ⚠️ Note: Some teachers might prefer “so” here, but since the worksheet says “for,” we’ll use it.

---

9. They moved their toys to the side. They had room for the race track. (and)
→ They moved their toys to the side, and they had room for the race track.

*(“And” connects two related actions — moving toys made space.)*

---

10. She does not play the piano. She plays the flute. (but)
→ She does not play the piano, but she plays the flute.

*(“But” contrasts two musical instruments she does/doesn’t play.)*

---

11. The cake is dry. The caramel sauce is good. (but)
→ The cake is dry, but the caramel sauce is good.

*(“But” contrasts the quality of cake vs. sauce.)*

---

12. We can have pizza for supper. We can have spaghetti. (or)
→ We can have pizza for supper, or we can have spaghetti.

*(“Or” gives two options for dinner.)*

---

✔ Final Answer Key:

1. She did not go to the park, but it was too late in the evening.
2. They arrived early at the show, and they had great seats.
3. My family has never been to Washington, but we have seen Boston.
4. I really like chocolate cake, but I am too full for dessert.
5. We could start the movie now, or we could wait for Julia to arrive.
6. I am allergic to cats, yet I love to pet them.
7. Mark finished his homework, so we can go play outside.
8. You cannot go outside, for it started to rain.
9. They moved their toys to the side, and they had room for the race track.
10. She does not play the piano, but she plays the flute.
11. The cake is dry, but the caramel sauce is good.
12. We can have pizza for supper, or we can have spaghetti.

📌 Tip for Students:
Remember the acronym FANBOYS for coordinating conjunctions:
For, And, Nor, But, Or, Yet, So.
Use a comma before the conjunction when joining two complete sentences!
