Students take turns
rolling the die and tallying up their score.
The "kicker" of the game is that when you roll a one, you loose all the points you have accumulated. So the players had to know when not to press their luck and give up their turn to their partner so they wouldn't loose everything.
After we played I asked the students to explain what "equally likely" meant. They did a fantastic job connecting the term to their probability of rolling a one. Mission accomplished!
