DS7 runs about the same way and at a similar place in math. Watching videos on quadratic equations, even some calculus stuff, sometimes doing math stuff through another app, etc. He also stops when he thinks he has the idea. Since he like complex problems, I'll sometimes find him a problem that calls on some subject he's ran through.

My overall thought on this, however, is: Whatever he is doing certainly works for him! Even if not every subject sticks with him, he'll reinforce it later. Traditional approaches and methods may not be applicable. I'll trust that he picks back up on the peripheral skills and structured solving when he is ready to do that. Maybe this style combined with enthusiasm is as significant to the skills of a kid who is functioning four or more standard deviations out in math as is the basic intelligence they bring to bear on it. I don't want to break a good thing.
