New York State Learning Standards learning standard: 4L1 · compound sentences, fragments and run-ons

How we explain it

Children can open this short lesson before they practice.

  1. A complete sentence has a subject and a verb and makes sense alone.
  2. A fragment is missing a part. A run-on jams two sentences together with nothing between them.
  3. Join two sentences with a comma and and, but, or or so. The verb must agree with the subject: she runs, they run.

Example: Fix the run-on: “Sam likes art he paints every day.” There are two ideas: Sam likes art. He paints every day. Join them with a comma and “and,” or split them. Answer: Sam likes art, and he paints every day.
