Reddit reviews The Autism Acceptance Book: Being a Friend to Someone With Autism

Here is the generally used textbooks for this school year.

I'm glad you're wanting to help, but I'd really encourage you not to do anything with the puzzle piece. It's used as a symbol to mean that autism is a puzzle that needs to be solved, which is really hurtful. Here's a good blog post about it. If you do a bit of googling, you'll find many more.

Some good books are Since We're Friends and The Autism Acceptance Book if it isn't over their heads.

What's more important than awareness is acceptance. If kids learn that autism is a series of "can'ts" (can't speak, can't make friends easily, can't understand sarcasm or jokes, etc), they'll come away with the impression that it's bad. The message that needs to be taught is that autistics are "different not less." I've read about a lesson being done with slightly older children where they name things that are different about themselves or that they struggle with ("I'm the only one here with red hair," "most of my letters come out backwards," "I moved here from Canada," etc) - then the conversation shifts to a discussion of how just because everyone is different and has different issues doesn't mean they can't still be friends or that some people are better than others. Autism isn't something to be feared. Make sure the other kids know that.

Some good ones for him and/or his class: Different Like Me, Can I Tell You About Asperger Syndrome, All Cats Have Asperger Syndrome, What it is to be me, The Autism Acceptance Book, The Juice Box Bully, Ethan's Story, The Bully Blockers.

Of Mice and Aliens and the other books by Kathy Hoopman are awesome. My son read them them all in a day.
