Conjunctions Worksheet
- 1st grade
- CCSS L.1.1g
A free, printable conjunctions worksheet for 1st grade. Your child circles joining words, picks and, but or or, and joins sentences with so and because. Answer key included.
What's inside
- Page 1: circle the conjunction in 6 sentences, then choose and, but or or in 5 more.
- Page 2: join 3 pairs of sentences with so or because, then finish a sentence about yourself.
- Page 3: answer key.
How to use it
- Teach or review the rule first with the conjunctions 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
Conjunctions join words and ideas. The 1st grade standard names five: and, but, or, so and because. Part C works on so and because, which kids mix up most because they join the same ideas in opposite directions.
