John Saxon’s Math books, how homeschool parents can use them...

Like new. It explains, not only what editions to use and what you need to be successful with each edition, it also highlights their reasoning for the how before the why method. It shows how successful the program has been with a gentle overview of how the math program came to be. While the book mostly focuses on 5/4 and up through Advanced Mathematics, it can easily have the same ideas and methodology applied to K-3. Definitely worth the read if you plan to stick Saxon out for any amount of time.
