Today we all know that benefits of math are considerable. Math is not a subject one learns by reading the problems and solutions. American children have very little practice with multi-step problems, and very few opportunities to think their way in to and through problems that do not look like all the others. With a packed curriculum and the increased emphasis on testing, our children are taught tons of procedures - but procedures disconnected from when to use them, and why. Sustained thinking - the key ingredient to math success - is painfully absent in too many math classes.
