Okay, looking at the test results, my DS scored lower across the board than my DD did. In fact, my DD does seem to learn at a faster rate and things come easier to her. My DS, though, and it may just be our perception, seems to have more of an intuitive grasp of things without ever having been taught them. I actually do think my DD is somewhat more gifted than her brother, but, like I said, he is further along in math than she was at this point. Also possibly important (or not) DD was 7 when she was tested and had 2 years of elementary school under her belt, and DS was 5.7 when he was tested and only had 2 years of play-based preschool under his belt.
