Improving America's Math abilities

America needs a common math curriculum. We can build on a common math curriculum in many ways - showing a variety of approaches to solving the same problem (remember people learn in different ways. Some of us are more visual etcetera) we can build a rich set of practice questions (I've been frustrated by the lack of a substantial number of practice questions for my kids). We could have on-line tutors who understand the content because its a common cirriculum. Imagine several different teachers each creating their own You Tube video on how to solve the same problem. If a student doesn't "get it" based on one teacher's lesson, then s/he can watch another teacher - there might be a subtle difference, that the student picks up on that allows the student to understand.
