There are also plenty of tips for teachers for adapting their curriculum for students with intellectual disabilities. The government offers a list of extra resources to look at for extra information on intellectual disabilities.

Stewart, S. & Flath, C. (2010) My Name Is Not Slow: Kids with Intellectual Disabilities. Mason Crest Publishers.
This book is for children age 10 and up. This is one book in a series of books produced by IDEA (Individuals with Disabilities Education Act). It is a great resource to help students understand what intellectual disabilities are and that they need to respect classmates who may have an intellectual disability. I like it because it raises awareness and demands respect for individuals living with an intellectual disability.

Despite the fact that the title int his book uses an old name in referencing intellectual disabilities it is a useful resource. It covers the basics by defining and addressing what 'mental retardation' is and how one is diagnosed. It outlines characteristics and other challenges that present with children with intellectual disabilities. It offers tips for teachers & philosophies around teaching children with intellectual disabilities.
