As parents, we have to take more responsibility in being personally involved in our children's education. Please don't expect our educational system to do everything. Try these products and you will not be sorry! My only comment is that when you get to Algebra, START OUT, on the 12 and up instead of the 5 and up. To me, they begin almost identically anyway and I think if you had going from one to the next that they may become discouraged because they have to essentially start over on the 12 and up version.
