This is a game that involves a group of four students turning over a card and changing the number on that card to a percent, fraction, and a decimal. After they've each completed their transformations, they look at the other group members' numbers and order themselves from greatest to least. Points are assigned for greatest down to the least value. After working fourteen problems, the points are tallied and the person with the most points win.
This is a great collaborative learning experience for students. Most students love the competition between each other. It is great for reinforcing a skill that is sometimes difficult to master.
