Everyday Math is a spiral. Instead of mastering a skill and moving on, it touches on a lot of things in cycles. It also requires quite a bit of reading (word problems, ect) and writing (narrative explanations of processes) compared to many other math programs. I know nothing about Saxon math. Lots of kids with difficulty reading rapidly fall behind in Everyday math. I would avoid any program using Touch math (counting the dots on numbers), there's some evidence it prevents kids from memorizing math facts.
