This resource contains 20 cards that have questions involving operations of decimals. Students start out by solving any problem they want, and the go around to find their answer. With each answer a cartoon character will go with it, and then students solve the problem below. This activity is simple to use by posting the cards around the room, and letting students work through them at their own pace. Great way to review for a test, or test prep! A list of characters is included for students who may not know who the cartoon characters are.
