Thanks everyone, I think I will drop a note to the teacher. cmac, great idea to ask the teacher's advice on how to deal with the perfectionism! I am definitely going to use that approach.
And, this afternoon DS and I had a nice discussion about the assignment and we worked through a few of the other problems (she sends extra home for fun)without incident. So maybe it will be a good learning experience for him, making him realize that he needs to pay attention a bit more, at least during enrichment!
Also, he just started an exercise class twice a week that I think is working really well for his sensory diet and that seems to have improved his overall attitude significantly this week. It seems to me that when his sensory seeking needs are not being met his ability to self regulate other things is significantly reduced.
bzylzy, I love your "silly humor" approach! That is definitely something I think DS would respond to.
