I could have also wrote this post about ds7 last year. My son is not physically able and was told he could not play by the other boys. He could sometimes get the girls to pretend they were all animals or something similar. Mostly, he read on the playground.

This year he is at a gifted private. Ds is actively playing at recess with the boys- sometimes team sports and others imaginary games. He is much happier.

I'm sorry to hear that your ds is not being included. It's hard to be different. Maybe he could start another game with friends? Or play with other kids who are not in the game? Does the teacher see what's happening at recess?
