My son (9) says: "Kindergarden is made to be boring." and he predicts that every year will be less boring. He suggests that you teach him math, adding 1- 50, then subtracting 1-30, then teach him multipling 0-11, then dividing 2-10. He will question stuff on his own, then teach him that right away. He may get bored later, but maybe they'll skip him up.

I've heard a lot of Moms and Kids liking the Singapore Math workbooks.
