Try these interactive math games to test and train the mind. Good explanation is given for each of the games. Requires Java.

An introduction to exponential equations that describe growth and decay over time. Variables and constants in the equation are explained.

This illustrated math lesson plan shows how important levels of accuracy in measurement are. The answer can be different since a scale only accurately weighs to the nearest tenth of a gram instead of to the nearest hundredth of a gram....

The purpose of the task is to show students a situation where squaring both sides of an equation can result in an equation with more solutions than the original one, because it is possible to have two unequal numbers whose squares are...
