Explain that a simple sentence expresses a single, complete thought, and contains a subject and a predicate. Explain that a compound sentence is 2 or more simple sentences joined together by a comma followed by a coordinating conjunction. Use FANBOYS to review coordinating conjunctions. Students will use two columns and create compound sentences by combining Column A and Column B with a coordinating conjunction.
Next, explain that a complex sentence has one independent clause and one or more dependent clauses. Students will read some examples, like "Since my computer is broken, I have more time to read my book." They will then identify the independent and dependent clauses. Then, students will determine if sentences are simple, compound, or complex.
