Do consider asking the teacher to consider geometry (or some such thing) over "drill and kill." If he's enjoying the multiplication work, great! But if not, please do consider another direction.
There *are* ways to move forward in math without forcing the times table issue too early. Remember that memory and conceptual grasp are two different things for a kid. Math facts do not have to be a sticking point for conceptually GT kids if the teacher is willing to go a little further afield.
JMHO, having been in these shoes last year. Making math all about memorization is, sadly, a good way to make a mathy kid hate math. He's ahead, so why do that to him?
