Review: A compound sentence consists of two independent clauses (equal sentences) joined by a coordinating conjunction. An independent clause makes sense by itself because it has a subject and a verb. That is, it could be a sentence all by itself. The coordinating conjunctions used to join the two independent clauses are the “FAN BOYS”: for, and, nor, but, or, yet, and so. What's important is for you to find the two important thoughts in a compound sentence.


Print a copy of this exercise. Underline the two independent clauses in each of these compound sentences. Circle or box the coordinating conjunction that joins them.

Each underlined part could be a sentence by itself. The coordinating conjunction so is used to join them into a single sentence.
