Have you tried going to a teacher store and buying some teaching supplies - like manipulatives or math games? It might me able to help and be fun without having to sit and do math problems
I second this. I can remember substitute teaching, and they had manipulatives to teach adding and subtracting where you have to carry. There are so many games you could play with her. Keep it fun. I can remember butting heads with my dd when she was younger, and needed help with homework.
