Boysmom,
I'm so sorry that happened. We've been lucky to not run into that kind of teacher in our ds's education, but I'm aware they're out there: the rare teacher who finds it too challenging or threatening to teach a gifted child and rather than celebrate seeks to diminish and "put that child in his/her place." It sounds as if you have a great advocate in your ds's second grade teacher. I don't really have any advice. Perhaps others here will be able to help with that. I will say that with you and your dh as advocates this will probably not cause long-lasting damage--particularly if this teacher has been careful to keep her opinions to herself rather than pass them on to your ds.
