Great activity to engage students in converting negative exponents to positive.
Print cards and cut cards (preferably on card stock). Laminate them if possible for prolonged use.
Distribute one card to each student and have them stand around the perimeter of the room with about are arms length between each student. Prompt students that they will be walking around the room to find their equivalent exponent card.
Once students find their match, have them stand together along the perimeter of the room again.
About 5 minutes to find matches. Write matching cards in their notebooks. Collect and redistribute as many times as necessary.
