Conjunction Worksheets - Free Printable

Let’s go step by step through each sentence and pick the best conjunction: and, but, or or.

---

1. Ashley has a peanut butter ___ jelly sandwich in her lunch box.
→ Peanut butter *and* jelly is a common pair — they go together.
✔ and

2. Lindsay ___ Jennifer are sisters.
→ Two people being sisters means they’re joined together — use “and”.
✔ and

3. Sean wanted to learn to play the guitar, ___ his mother wanted him to learn piano.
→ Sean wants one thing, mom wants another — that’s a contrast → use “but”.
✔ but

4. Greg studied for his spelling test, ___ he still didn’t get an A.
→ He studied (good effort), but result was bad → contrast → “but”.
✔ but

5. Would you rather eat a hot dog ___ hamburger for dinner?
→ You’re choosing between two options → use “or”.
✔ or

6. When I grow up, I think I want to be an electrician ___ a plumber.
→ Again, picking between two jobs → “or”.
✔ or

7. Georgie was going to clean the house, ___ she’s too tired.
→ She planned to do something, but can’t because she’s tired → contrast → “but”.
✔ but

8. The grass is very long ___ I have to mow it.
→ Long grass leads to needing to mow — this is cause and effect, but none of our conjunctions show that directly. However, “so” isn’t an option. Between “and”, “but”, “or” — “and” fits best here as connecting two related facts.
Wait — actually, let’s think again. Is there a contrast? No. Is it a choice? No. It’s just adding info → “and” works.
But sometimes “so” would be better — since we don’t have “so”, and “and” connects ideas logically, we’ll go with “and”.
Actually — hold on! Let me check if “so” is implied. But the instructions say only use: and, but, or. So among those, “and” is correct.
✔ and

Wait — maybe not. Let’s read again: “The grass is very long ___ I have to mow it.”
This implies consequence — long grass → need to mow. Since “so” isn’t allowed, and “because” isn’t either, the closest logical connector from the given choices is “and”. Some might argue “so” is needed, but per worksheet rules, we must choose from and/but/or. “And” is acceptable here as joining two true statements.
Still ✔ and

BUT — wait! Actually, in many elementary worksheets, this kind of sentence uses “so” — but since “so” is not an option, perhaps they expect “and”? Or maybe I’m overthinking.

Alternative thought: Could it be “but”? No — no contrast. “Or”? No — not a choice. So yes — “and” is the only possible answer.

✔ and

9. Which is your favorite holiday, Halloween ___ Thanksgiving?
→ Choosing between two holidays → “or”.
✔ or

10. We earned twenty-two dollars selling lemonade ___ cookies.
→ Selling both items — so “and” connects them.
✔ and

Now let’s list all answers clearly:

1. and
2. and
3. but
4. but
5. or
6. or
7. but
8. and
9. or
10. and

Double-checking #8: “The grass is very long and I have to mow it.” — Yes, that makes sense. It’s not contrasting, not offering a choice — just stating two things that are connected. “And” is fine.

Final Answer:
1. and
2. and
3. but
4. but
5. or
6. or
7. but
8. and
9. or
10. and
