P.s. I think 6 yr. Old boys are supposed to act immature, but what do I know?
I don't think many parents have their kids educational needs figured out by that age yet. Have you tried teaching him something new lately to respark that visualization or however he was doing the math. I wouldn't rehash the (+-*\). There's some kind of calculus by kids for kids book I saw online that's supposed to be for 7yr. olds and up, and there's the hands on equations that's supposed to be for ages 9 and up. I'd look at those and see if offering him something new helps gets his head back into it. Especially as fast as you say he learned the fractions.
