How to use this worksheet
- 1
Read each sentence aloud before choosing. Ears catch “the children runs” faster than eyes do.
- 2
Use your child’s own writing for a follow-up: finding one compound sentence or one possessive in their journal makes the rule stick.
- 3
On the synonym sheet, act out the “weakest to strongest” words — whisper, talk, shout — to feel the difference in meaning.
