I always remember my dear departed grandmother referring to something called "New Math" when I was a youngster, but at the time I wasn't interested enough in whatever it was to look into it. However, I just read the Wiki page on it: http://en.wikipedia.org/wiki/New_Math And it looks like something that got phased out shortly before I entered grade school. From the face of it, it looks like a crazy, overoptimistic project, but I wasn't really there for it. Is there anybody that actually experienced this and was taught this in school, or someone who parented a child that encountered this movement? How did it work out? Is there some validity in this manner of early instruction in children "in an ideal society," at least? Or was it just misplaced to begin with--driven by cold war fears?
