Sentences are built in different ways. A simple sentence has one complete idea, such as The dog barked. A compound sentence joins two complete ideas with a comma and a word such as and, but, or or so: The dog barked, and the cat ran. A complex sentence has one complete idea and one idea that cannot stand alone, usually begun by a word such as because, when, if or after: The dog barked because the cat ran.
On this worksheet your child reads ten sentences and writes simple, compound or complex for each one; the three words are in the instruction. Building Confidence uses clear one-idea and two-idea sentences, On Level adds the complex words, and Challenge Me uses longer sentences and words such as although and unless. Ask your child to count the ideas and to look for the joining word.
