Any tips for supporting an autistic child tell their friends and classmates?

We have told our 8yo his diagnosis which seemed to go well. He has mentioned it to a few of his friends which we are taking as a good sign. We would like to run a session with his friends/class so that all the kids are getting good info about autism. Any tips would be most appreciated. Any good videos/teacher resources?Has anyone used the resources provided by NAS? Are they good? Thanks Jen
