What kids do

“A compound sentence is two whole sentences joined with a comma and and, but, so or or. Circle Simple or Compound.”

Printed on the sheet:

  1. Cover the joining word. If you have a whole sentence on each side, it is compound.
  2. The frog jumped into the pond.
  3. It was cold, so I wore a hat.
  4. My brother and I built a fort.
  5. I wanted pizza, but we had soup.
  6. The puppy ran and jumped.
  7. We can play inside, or we can go to the park.
  8. The stars twinkled in the dark sky.

Teacher tip

Have kids cover the joining word with a finger. If both sides are full sentences, it is compound.

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.
  • Give a minute at the end to reread the work out loud to a partner.

Watch for

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

Talk about it

  • Can you find a sentence like this in your reading book?
  • What did you change when you reread your work?

Take it further

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