Another one here with early math-fact memorizers (not drilled, either--my kids are just hyper-memory kids and this kind of stuff is a major strong point). DS5 has a lot of his times tables down, certainly all addition and subtraction to 20, though I think occasionally he very quickly computes.

(Uh, so excited for kindergarten. Sorry, offtopic.)

Anyway, DD9 is really good at science but seems only MG in math to me, though I'm not clear how far she could go if encouraged. Her math seems highly serviceable but not an area of extreme ability, but she has a very scientific mind and asks fabulous questions. I think she could definitely be a scientist, but maybe not one where extremely high math is very important. I'm not sure she missed a point on a science test all year, but she definitely misses points on math here and there.
