My kids ask me for math problems. The latest for my four-year-old daughter:

3 + 2 =
7 + 3 =
4 + 4=
5 + 6 =
10 + 10 =
10 + 1 =
4 + 2 =

3 + 1 + 2 =

8 - 1 =
9 - 1 =
5 - 2 =
10 - 3 =
4 - 3 =

6 + 6 =
7 + 7 =
1 + 1 + 1 =
1 + a = 2; a=
2 - a = 1; a =
a + a + a = 3; a =


She got them all right.

She's extremely bright, and says she will ask her preschool teachers for more of this 'easy math' as we call it -- BUT I do wonder how much her 7-year-old brother helps her. When I asked him, his answer seemed seemed credible. AND he wailed at his mom that he wants her to be able to get some wrong.
