Thank you all for your comments! I always appreciate coming to this site and hearing from people who actually get what I am talking about.
Zen, I did actually do something along the lines of your suggestion and definitely got a somewhat defensive response.
However, I had a really good hour long talk with the gifted teacher this afternoon and I do feel like she gets him and understands my concerns. She agreed, in more diplomatic terms, that the classroom environment was not good for him and that it isn't just something "wrong" with him, which is how the homeroom teacher seems to present things to me. That's the good news. The bad news is that we have no idea who the 4th grade teachers will be at our school next year do to some staff shifting between schools in the district. While she usually has some say about where her kids are placed, she literally doesn't know the teachers who are coming in so it's basically a crap shoot.
So unfortunately that doesn't reduce my concern for next year at all.
