Free 5th Grade Commas in Complex Sentences: Introductory Clauses Worksheet

A 5th grade comma worksheet on complex sentences. Students find the dependent clause that begins with a subordinating conjunction (when, because, although, if, after, before, while, until, since), learn the rule that a dependent clause at the start of a sentence is followed by a comma, and see that no comma is usually needed when the dependent clause comes at the end. They choose correct sentences, add or remove commas, flip clauses around, and write complex sentences of their own.
