Thanks to everyone and what great advice. We plan on pursuing the Davidson Institute. I'm hoping they can give us advice on strategies to use with the school.

We figured kindergarten would end up being more social and fun and hope to supplement his education at home or find a tutor. We purchased some 2nd and 3rd grade math workbooks and he's blowing through those. But I think he'd do even better working with a tutor. Is it necessary to find a tutor that works with gifted kids?
