Students use probability to help develop a strategy to win this Roller Derby game. They place 12 markers in columns marked 1-12 however they like. They roll 2 dice and find the sum of the dice. They then take the marker from that column. First one to have an empty board wins! Let students play through once and then have them find the sample space of rolling 2 dice and the probability of each sum. Then have them play a second game with the knowledge of the probabilities.
