Grammar: SENTENCE OR FRAGMENT? GAME #1 Determine if what you read is a complete sentence or a fragment. Select your answer from the pop-up menu. To help you decide, put the words "I believe that" in front of the sentence or fragment that is written. If it makes sense and is a complete thought, it is a sentence. If the thought doesn't sound right or is incomplete, then it is a fragment. Tools Activity created by: Tracy Boyd This activity was created by a Quia Web subscriber.
