This document defines and provides examples of common sentence issues: fragments, run-on sentences, and comma splices. It explains that fragments lack a subject and verb, while run-on sentences and comma splices join two independent clauses without correct punctuation. The document offers ways to fix each issue, such as adding subjects or verbs to fragments, and using coordinators, subordinators, semicolons or periods between independent clauses for run-on sentences. Activities provide practice identifying and correcting these sentence problems.
