He has always been so random.... At times he can focus and just do the easy problems and at other times he can rattle off some pretty complicated algebra, statistics, and geometry problems.
Does his concentration/focus seem to vary in other subjects?
We had some real issues with a principal who didn't think DS11 knew 5X1. It was difficult to even figure out where we could connect on the conversation! Anyway, lots of anxiety in our son, perfectionism, boredom, never believing that an easy answer would be the right answer, etc. The thing that clicked with me was when we found out that kids with ADD can have varied attention depending upon the day, time, and circumstances. It seems that sometimes he really was doing the algebra fine, and other times he wasn't answering 5X1 (even though he knew the answer - duh).
I don't know if this applies at all. Just keep asking the questions and you'll figure it out. It has taken us a few years to find the right questions to ask!
