To be perfectly honest, this is why I don't teach DD any math outside of school. After I taught her subtraction with carrying in about 10 minutes because she asked (I forget how old she was, but not old enough to be covering this), it hit me that I should probably shut up. She's good at math, but not a prodigy. While she has an interest in math patterns, she doesn't ask to learn it. Meanwhile, DS4 is playing with her Flashmaster and mastering all the addition and subtraction tables. I'm wondering if I should take the thing away from him. wink

She is more challenged by all the blah blah cumbersome blah of how they teach math than anything about actual method or computation, always. She grasps pure math and computation very fast. I'm sure I could teach her long division this afternoon, but they'll complicate and draw it out and make it actually harder. Oh well.
