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.
