This site offers FREE interactive math tools: qualitative grapher, piecewise linear grapher, linear transformer, function analyzer, quadratic transformer, system solver, plopit, and proportioner. Originally the interactives required special software, but they now run directly from the web site without any special installation or download. The interactives all include a real-time connection between math concepts (graphical or symbolic) and the representations. The activities provide visual illustrations to enhance algebra class. They allow for accelerated learning. And you are even able to save images to share with classmates.

The "Qualitative Grapher" demonstrates the meaning of a function and see how it can be seen as something changing over time. The "Proportioner" highlights scale and proportion and allows you to compare image dimensions. All of the other individual activities highlight other upper level math skills. This site requires Java and Adobe Acrobat. You can get both from the TeachersFirst Toolbox page.
