Thanks so much for the quick response! I'm really going to need to weigh our options. For some reason, it was one thing in my mind to START with B, but something else to skip over it to C. LOL I'm not sure why. I don't want to get B and have the same thing happen as did with A-just rush through it with it being a bit too easy. At the same time, I don't want to push her. She's only 5, she just LOVES math and really understands it well. She also loves playing Chess-it's just how she thinks. I will think hard about your suggestions. I may do B and just do the lessons that it looks like she really needs. That way I'll also have B for my other children when they get there. I'm going to keep thinking.... Thanks again for the suggestion!
