The Shodor Educational Foundation develops and distributes
a number of excellent interactive tools for learning about functions
and numbers. By clicking on the following links, you can load
each Java-based tool. For detailed instructions, click on the
*Help* tab at the top the tool's page.

- Function Flyer is a nice graphing utility. Try graphing the function 1*x+2 and see what the sliders do.
- Data Flyer is similar to Function Flyer, but you can plot some data points on the same graph as the function.

New tools are being added to the Interactivate materials on a regular basis. Check them out!
