The Lexile Framework for Reading is an educational tool that uses a measure called a Lexile to match readers with books, articles and other leveled reading resources. Readers and books are assigned a score on the Lexile scale, in which lower scores reflect easier readability for books and lower reading ability for readers.
So, your child came home from school with an Scholastic Reading Inventory with a lexile score. What does it mean and how can it help you and your child find good books to read. Here is a nice resource to explain lexiles and how to determine the lexile level of the book your child wants to read.
