About Fragments and Run-Ons
What this skill is
A fragment is an incomplete sentence missing either a subject, a verb, or a complete thought. A run-on sentence incorrectly fuses two or more independent sentences together without appropriate punctuation or connecting conjunctions.
When children learn it
Recognizing and correcting fragments and run-on sentences is explicitly taught in 3rd and 4th grade (CCSS L.4.1.f) and serves as an ongoing focus in 5th grade narrative and expository revision.
Teaching Tips
- Have your child read the sentence aloud while walking across the room: tell them to take a physical step for each complete thought. If they keep talking without stopping, it is a run-on that needs a period or conjunction to divide it into two clean sentences.
Common Mistakes
- Thinking a sentence cannot be a fragment if it contains many words, overlooking long dependent clauses standing alone.
- Fixing a run-on simply by inserting a comma without a conjunction, creating a comma splice error.
- Failing to hear where one complete thought ends and the next begins when reading aloud.
