Compount Interest Simulator for Personal Finance Class

Here is a great new tool in the Illuminations site from NCTM that provides a good learning experience related to economics. The Compound Interest Simulator applet will allow you to investigate savings account earnings, credit card debt, and a stock market simulation. How well this can relate to the real world and the economic situation we are in now. Group your students into these 3 areas, have them experience the tool, then have discussions about what would be the best alternative for them as they see what is happening today in our economy.
