A.M.
personally, I'd relax about all of this. She is 4 years old and has a lifetime ahead of her to do schoolwork, regular work,etc... Children at this age learn best through child based play. Having said that, if you want to work on her letters and numbers you have gotten some good advice from the other M.'s. I would caution against the advice, though, suggesting that you put consequences on her not doing it correctly, or marking her papers 'wrong'. She is 4. I'd say you'd want to foster a positive and happy association with learning and I don't think that would be the way to do it. Good luck.
