What kids do

“Two short sentences can be one longer sentence. Circle the best joining word, then write the new sentence. Put a comma before the joining word.”

Printed on the sheet:

  1. 1. It was raining. We took an umbrella.
  2. 2. I like apples. I like pears.
  3. 3. Sam wanted to play. He had to do his homework.
  4. 4. The puppy was tired. It took a nap.
  5. 5. Mia can swim. She cannot dive.
  6. 6. We went to the park. We played on the swings.

Teacher tip

Make a quick chart: and adds, but shows a change, so tells what happened next.

How to use it

  • Build a sentence on the board with word cards before the sheet.
  • Have kids clap once for the naming part and once for the telling part.
  • Let early writers draw first, then talk, then write.

Watch for

Kids who think a long sentence must be a run-on. Length is not the problem; missing joins are.

Talk about it

  • How do you know when a sentence is complete?
  • Which sentence on your sheet are you proudest of? Why?

Take it further

Have kids find and fix one sentence in their own writing journal.
