Some good advice on this thread.
My 2 cents. I have an 8 year old, this, in my limited experience, sounds to me like he is bored.
My child ended up with multiple assessments when younger and the consensus was that he should be promoted 2.5 grade levels ahead just to keep his attention since he was just too far ahead versus his classmates.
Imagine you, at your age, with your intelligence, having to sit through grade school, and do homework.
I did not catch if you have taken him for professional assessments.
He has all of the virtues I dislike and none of the vices I admire. Winston Churchill.
