Debbie,
Is DS7 happy with school in general?
How long are we talking about - 15 minutes with battle or 2 hours?
Can you arrange some kind of 'placing out' of certian types of homework?
I guess I would suggest that you observe various possible recieving classrooms, and get the wheels moving to ask in writing (not email) for a consideration of either another full skip or another bump in Math or both. The school may save you some money by doing a WISC test after you request him to be reevaluated.

I think it's also fair game to ask the school when they expect to get the results. Of course if you want to know 'what he knows' in the world of 4th grade math 'right now' - try an weekend full of ALEKS.com and see how much pie he scores. Have him copy some of the questions he completes and the answers in his own handwriting so the school can see what he can do, and where the gaps are.

Best Wishes,
Grinity
