Just wanted to mention two things I wish I'd known when we started homeschooling:

(1) Children need time to "get over" school. This is called de-schooling. A month of de-schooling per year of schooling is the general recommendation. Re-doing a bedroom sounds like a great de-schooling activity!

(2) There's a list called TAGMAX which is for folks who are homeschooling gifted children. It's a great place to ask any question regarding curricula or surviving homeschooling. Google TAGMAX to find info. The subscription process is archaic, but it is worth it.
