HK, logic, patterns, sequencing are all strengths. Portia, he is great with Legos, following 3d building instructions. Handwriting is okay, probably on par for age, I think. Spacing is not great. Doesn't seem to have much coordination hand to eye, not great with balls. But is pretty coodinated as far as gross motor goes, ie, bike riding. Rather clumsy, but not cautious near other people.
As far as looking at a pattern shape, and telling if it is the same, shouldn't a six year old be able to do that no problem, no matter what, gifted or not?
