In this math lesson, learners are given 15 chips and a number line labeled from 2-12. They are instructed to place their 15 chips on the numbers which they think will represent the sums when two dice are rolled. The object of the game is to be the first person to remove all of the chips. A chip is removed if it is on a number that corresponds to the sum rolled. The game is analyzed and the concepts of probability, sample space and game winning strategies are discussed. Learners place chips on their number lines and play the game again to implement winning strategies.
