I split students into two groups to play the game. We go over the rules of the game and the "risks" that can be made. I show a slope question to one team, the team collaborates and works on it (sooner or later they figure out that to benefit the team, they need to make sure everyone knows how to solve it, not just their friends). When the time is up, I pick a student randomly from the team (each person writes their name and submits it to a jar) and that person solves it. If they can't get the answer, the question goes to the other team (another random chosen student). If they do get the slope question right, they can keep the point or risk it for two points. A die is rolled and whichever number comes up is the risk that is assigned. There are 10 questions and range from finding slope between two points, counting slope from a graph and table, as well as linear components.
