Thanks for the suggestions! To clarify: I'm not trying to stuff math down his throat. Quite the opposite! He wants to learn more. He's bored. Legos, playing store and other preschool fare have lost their charm. He creates his own complicated scenarios and acts them out. Life would be 100X easier if I could just give him a couple of preschool worksheets to color each day.
He can add and subtract, skip count, count to 100, solve simple story problems, blah, blah, blah. His Math aptitude is much higher. He enjoys creating story problems and then is disappointed when I can't solve them. I'm was good at math, but it always bored me silly. Having a little boy who counts the number of peas on his fork for fun is different to say the least.
