Name of nasa or other educational tv show?

Question

I watched this tv show when i was younger. It was a very well constructed program which illustrated many math concepts by means of computer animations. It usually had a green background, and a small pointer, like a hand, courser would move around while a narrarator explained how the concepts relate to each other. please help me find out its name. Thanks!!
