Thanks for the input. I was thinking of more like an hour a day... maybe even twice a day. Thats more the level of repetition I would think necessary. Having him do it in school once and then again at home seems rather easy to me. If there is some payoff, any payoff really, I think it'd be worth it. Once those connections are redone or a new part of the brain takes over, he'll be golden.
Sidetrack/I stopped in to school unannounced 2x this week. Once I found he was on the computer playing and on the other he was sitting unattended doing zero.
I was really pissed and addressed the school, but if they have time for him to do that, then he can do this instead.
