What is your level of understanding in math? That would be the determining factor. On other threads, I've heard of a Japanese program. Most commercial ones, I don't care for either. There are some older ones that are good, but it depends on the grade level.
Thankfully, my daughter is being tutored in Algebra by her father, using Saxon. They both love the program. My husband knows high math and his father was a rocket scientist, instilling a good understanding and appreciation for the subject.
As far as Saxon being charasmatic, you sure couldn't determine that from his books. Black and white...no flashy colors. My daughter prefers this. And very honestly...it works for her. :o) Can't argue with that.
I've heard good things about Chicago Math...and a program called Singapore Math (not sure of the exact text name).
