My 7 year old son has/had similar behaviors in the classroom, yet they have all but evaporated with the right school and the right teacher. His teacher told us that the faster she has him work, the better he does. Negative behavior reports are gone, and his anxiety and dislike of school is gone as well!

And by the way, he was diagnosed at a young age with autism, but until he got his current gifted placement, his behaviors were an issue despite our request for more challenging work for him. His previous school, teachers, and administration only saw the autism and not the giftedness. It has been a HUGE change now that the school's emphasis is on challenging work for him!
