Two teams are given two different numbers. There are six different math problems for each of the numbers. These calculations are written on plates which are located face down on the floor.
First member of both teams start at the same time, they run to the play area and turn a plate of their choice, and calculate the sum/difference/multiplication/division. If that matches with their target number, they can keep the plate and return to their team and send next team member to continue. If number does not match, they leave the plate on floor face down and return to their team and next member continues. The team which has found all 6 plates matching their result, is the winner.
