Kindergartener is left out by his peers and is struggling because of it

My kindergartener was recently diagnosed with autism spectrum disorder. He is very bright and high functioning but struggles a lot with maturity and social skills. As a result his classmates leave him out of their games on the playground at recess. This upsets my son a lot. He wants to play but the kids don't want him there. I am not blaming the kids. I remember being that age and I understand it isn't malicious. His immaturity combined with his tiny stature makes them think of him as a little kid even though he is the same age.My wife addressed it with the teacher and she said she would keep an eye out but nothing has changed. He isn't being actively bullied and that's great but being left out still stinks. He's in a general education classroom right now and we plan to move him to inclusion next year with hopes that it will help, but we still have to get through this school year. They have 3 recess periods a day so it's a lot for him to be left out of. Occasionally the teacher will organize a game to include everyone but she isn't always there and can't always do that. When she does the kids usually complain about my son being involved. She stops it but he still hears it. Any tips? I'm so worried that this is the beginning of a very long road for my son and want to help him as much as possible. Everyday he tells me that no one likes him. via /r/Parenting https://ift.tt/2EAtqwM
