Grade level quizzes
A complete sentence needs a subject (who or what) and a predicate (what they are doing). A fragment is an incomplete thought missing one of these parts, like "Running through the park." A run-on sentence incorrectly squishes two complete thoughts together without the right punctuation, like "I love dogs they are so cute." You can fix these errors by adding the missing parts or using periods to separate your ideas.

Fragments and run-ons
A fragment is not a complete sentence: “Because we were late” leaves the reader waiting for what happened. A run-on joins complete thoughts without enough punctuation or a connector: “The bell rang we left.” Add punctuation and a conjunction to correct it: “The bell rang, and we left.”
