Educational worksheet for identifying sentence fragments and complete sentences, featuring a frog illustration.

Let’s go through each line one by one. We’re looking for complete sentences — that means they need to have a subject (who or what the sentence is about) and a verb (what the subject is doing), and they should express a full thought.

If it’s just a phrase or part of a sentence, we write “F” for fragment.
If it’s a full sentence, we write “S”.
