This is a familiar game called KABOOM! Students should be put in groups of 2-4. One student will draw a card (cut up and put in bags or cups) and solve the card using paper or a white board. If they solve the problem correctly, they get to keep it; if solved incorrectly it goes back into the bag. Another student in the group will check the problem using a calculator to ensure accuracy. If a child were to draw KABOOM, all of that student's cards go to back into the bag (game is never-ending)! Great for centers, or for early-finishers.
