Sounds like many boys who just can't sit still and want to stay moving - even as adults! It's not good or bad - just who he is. He will probably be a kinesthetic learner - one who has to do it to learn, touch, feel, manipulate to get it stuck in his brain. They make their teachers crazy as they fidget, move around, etc - but they are the guys who are the builders, engineers, athletes, teachers, etc.
