Teach math for my daughter

I just help my daughter with her math lessons. She is 6 years old and it is interesting like child to learn math, the way they discover things. Today our lesson was about finance, when she shoud cont bills of different values. In the begin she had counted the numbers of bills, not their values, and she didn´t understand how to do that. She sad: "Dad, you are wrong, here there are five coins". It was fun, but paciently I explained for her how to do. I exemplified with my bills that were in my wallet. Step by step she was understanding and she could make her lesson. These little things make a happy father!
