About this worksheet
Complete sentences and fragments mixed together, to circle S for sentence or F for fragment. Fewer, Standard or More give 8, 10 or 12. Includes an answer key.
What kids practice
A complete sentence has a subject, a predicate and a complete thought. A fragment is missing one of those parts, like "Ran to the bus stop." A run-on joins two sentences with no stop between them, or with only a comma, like "The rain stopped we went outside." Fourth graders write longer sentences, so both mistakes show up often.
Watch for
- Thinking a long sentence must be a run-on. A long sentence can be correct if it is joined the right way.
- Fixing a run-on with only a comma, like "I wanted pizza, my brother wanted tacos."
- Starting a sentence with because, when or after and never finishing the thought.
- Thinking a short sentence must be a fragment. "Maya laughed." is a complete sentence.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full fragments and run-ons guide for 4th grade.
