I think most first graders can count to 20, but I'm not sure all of them have their math facts down cold, at least not from what I've seen in the classroom.

Glad DD is happy, if she is happy to do the stuff at home, I think that's great.

I don't think either or my girls have learned much if anything in math at school that they hadn't already self-learned prior.
Just seems to be the way it goes. ((shrug))
