Thank you. I looked at Amazon but they were super expensive. I would want to at least try it before spending that much money. Wish the library had it. I think for the time being I'll supplement more with Khan Academy (where at least I can go in a logical order and the concepts are explained verbally!) and also take pieces out of Singapore Math. Unfortunately I have 3rd and 5th grade but not 4th and it's probably 4th I need at this point.
