It's All in the Notation

Copy onto cards the numbers below. Shuffle the cards and place them face down in a pile. Label the sections of a spinner "101," "102," "103," "104," "105," and "106."

One group member turns over a card and spins the spinner. The other group members compete to tell what number results in the number on the card when multiplied by the power on the spinner. Trade roles after every five rounds.
