I think the mindset question is tricky with gifted kids.

To me, we're really triumphing over a fixed mindset when DD get shown some new material she can't possibly do without help, freaks out, is taught it, fails a bit, freaks out again, keeps trying, and eventually succeeds and feels proud.

We're not necessarily triumphing when DD gets shown some new material that looks harder than she's used to, panics, keeps complaining at me about how it's hard because she's DD, then gets almost everything right because of innate ability, not because she has been taught anything new. I mean, it's better than usual. She had to try. But.
