I used this to homeschool two of my sons. It is so well laid out that I didn't need to teach either of them how to do it. The workbooks make sure the student has mastered each concept before moving on. The teacher's key has all the problems worked out step by step, and contains alternate tests, in case they do poorly on a test the first time. This is very straight forward math, no colorful pictures, just math. You can see the scope and sequence of the books at alpha omega's website. The books are consumable, and give space for doing the work in the books.
