Compound Sentences Worksheet
- 2nd grade
- CCSS L.2.1f
A free, printable compound sentences worksheet for 2nd grade. Your child spots compound sentences, joins pairs with and, but, or or so, and expands a sentence. Answer key included.
What's inside
- Page 1: label 6 sentences simple or compound, then join 4 pairs of sentences.
- Page 2: fix 3 comma mistakes, then expand a simple sentence.
- Page 3: answer key.
How to use it
- Teach or review the rule first with the compound sentences lesson. It takes about 10 minutes.
- Read the directions for each part out loud. Early readers can point while you read.
- Check Part A together before your child goes on, so any confusion gets fixed early.
- Use the answer key on the last page.
Prints on US Letter paper (8.5 × 11 in). No sign-up needed.
Tips for doing it together
- Keep it short. One page a day is plenty for most young children, and two short sessions beat one long one.
- Let your child read each sentence out loud before answering. Many mistakes get caught by ear.
- Mark a mistake with a small dot instead of an X, and let your child find and fix it. That's where the learning happens.
What your child is practicing
A compound sentence joins two complete sentences with a comma and and, but, or or so. The 2nd grade standard also asks kids to expand and rearrange sentences, which Part D practices.
Practice online
After the worksheet, the 10-question compound sentences quiz gives instant feedback and reads each question aloud. For a game, try Syntax Skies.
