John Lightner's Thinkquest Idea Page

This is my idea: we could have a graph with an equation like this and you could munipulate the graph by typing in a different m and b values. You could not only do it with parabolas but also with regular linear equations or elipses. It would be a sort of interactive math.

You could also have math problems, or puzzles, such as this one. They would take you through the problem step by step.
