Grade 1 grammar worksheet focusing on using coordinating conjunctions to complete sentences correctly.

Explanation:
We are given 10 sentences with a blank, and we must choose the best coordinating conjunction to fill in each blank. The options are: and, or, so, but.

Let’s go one by one and think about what relationship the two parts of each sentence have:

1. *It’s cold, ______ I wear my hat and my mitts.*
→ Cold weather causes wearing warm clothes. This is a cause-effect relationship. So we use so.
✔ *It’s cold, so I wear my hat and my mitts.*

2. *I want cake, ______ I’m not allowed.*
→ There’s a contrast: desire vs. restriction. Use but.
✔ *I want cake, but I’m not allowed.*

3. *I would go, ______ it is too far.*
→ Again, contrast: willingness vs. obstacle. Use but.
✔ *I would go, but it is too far.*

4. *I will finish my homework, ______ then I can play video games.*
→ This shows sequence or condition: finishing homework leads to playing games. “So” fits best for result.
(Note: “and then” would be better, but among given choices, so expresses the result.)
✔ *I will finish my homework, so then I can play video games.*
*(Though “so” + “then” is slightly redundant, it's acceptable here; “and” would just connect actions without showing cause—less strong. “But” or “or” don’t fit. So so is best.)*

5. *We washed the dishes, ______ we put them away.*
→ Two actions done in sequence, no contrast or choice. Use and.
✔ *We washed the dishes, and we put them away.*

6. *I know Michael, ______ I don’t know his brother.*
→ Contrast between knowing one person but not another. Use but.
✔ *I know Michael, but I don’t know his brother.*

7. *It will be sunny, ______ there will be no game.*
→ Wait — sunny weather usually helps outdoor games, so why no game? That suggests something unexpected — maybe the game is indoors or canceled for another reason. But the sentence implies a contrast: sunny (good) yet no game (bad). So but fits.
Alternatively, could it be *so*? No — sunny doesn’t cause no game. Could it be *or*? No — not a choice. So but is correct.
✔ *It will be sunny, but there will be no game.*

8. *I will read a book, ______ I’ll just watch TV.*
→ Two possible choices — reading OR watching TV. Use or.
✔ *I will read a book, or I’ll just watch TV.*

9. *The teacher is talking, ______ we need to listen.*
→ Cause-effect: because the teacher is talking, we should listen. So use so.
✔ *The teacher is talking, so we need to listen.*

10. *John got dressed, ______ he forgot his socks!*
→ Contrast: he got dressed (mostly ready), but missed socks. Use but.
✔ *John got dressed, but he forgot his socks!*

Now let’s list all answers clearly:

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

Double-check #4: Some might argue “and” works, but the phrase “then I can play” suggests consequence — *so* is stronger and matches the instruction to pick the *best* word. In grade 1 grammar, “so” is taught for results like this.

All others are solid.

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