Suggested Reading/Links/Materials** http://lexile.com ***Use this link to check out the Lexile of the book your child is reading for reading homework. The Lexile is a measure that is used to match readers of all ages with books, articles, and other leveled reading resources. Grade 4 Proficiency is 700-900 but students read at different reading levels. Ask your child their Lexile score. They should be reading books close to that reading level.
