Reduce Your Energy Use is a math activity in which students consider those electricity-consuming items in their homes that could be eliminated from their lives and they would still live comfortably.

In groups, students examine cards (provided) showing the energy consumption of various appliances The group selects three appliances to remove from their homes and discuss their choices with the rest of the class. After this discussion the students note their choices along with their reasoning on a worksheet (provided).

Next the students convert the electrical consumption of each appliance to the same format (rate, percentage, fraction or decimal). The appliances are then ordered from least energy user to the most. The students revisit which appliances to remove from their lives and justify their choices.

Extension ideas are included.

The activity is best suited for the middle school classroom. It supports numeracy outcomes in working with ratios, decimals and percentage and science outcomes related to energy use and electricity.
