This is a fun game to play at the beginning of our Rational Numbers Unit. I've cut out these cards, mounted them to construction paper, and laminated them so I can use them year after year.
Each student receives at least 1 card. (Depending on the size of your class, some students may need to take 2 because you need to use all the cards in order for the game to work.) Pick any student to start and read his/her entire card out loud. The student with the answer to the question will read his/her card next. This continues until it gets back to the person who started. I typically do one practice round, then do a timed round. The class that completes the activity the fastest earns a prize during the next lesson.
