My DH and I were have a discussion the other day about ADD Math. He is not a Math person. I liked Singapore for my DD8. We did 3 of those books, but he likes the nice clear boxes for instructions in Abeka. Since, we had an unused Abeka book for 5th, we are using it. I hate it. I refuse to make her do all the spiraling reviews, but the book covers so many different random topics and doesn't go into sufficient depth for many of them.
