Teach young readers what simple and complex sentences are, and help them understand the uses of each. Age-appropriate examples make concepts clearer. While the book's subject comes from the Common Core Language Standards, its table of contents, glossary, index, captions, and more make it a useful tool for teaching the Common Core Reading Standards for Informational Text, too. Includes simple review questions with an answer key at the back of the book. Addresses standards CCSS.ELA-Literacy.L.3.1, 1f, 1h, 1i, 2, 3.
