I really like Saxon, the repetition and building on concepts was great for my daughter who struggles with math. She was WAY behind, just didn't get it at all, until we started Math 2 halfway through her second year. She finished Math 3 on time. We do a lot of the work, because she really needs to do the same thing three times before she'll admit she doesn't know what to do and then to do it three times to cement it. My son did Saxon also but we used it as a rough guide because he really understands it and just didn't need all the explaining and all the practice.
You need the teachers manual, which provides you with a scripted lesson (we did not do all of the daily meeting every day, just whatever she needed some reminders on) and the student workbooks. You really don't need the meeting book.
