of data. The idea of formulating and communicating a strategy for playing a game should be familiar to them.

Presenting the task: The teacher should pass out the first student sheet and several number cubes (cubes numbered from 1 to 6) to each pair of students being assessed. The teacher should then read through the directions for the game and the three examples to be sure that everyone has an understanding of the rules of the game. Students should then be given the opportunity to play the game to see how it works.

Doing Part 1 (Questions 1 through 4) will be the first class period, and Part 2 (Questions 5 and 6) can be done in another one or two periods. Students should be given as much time as they need to gather a considerable amount of data as they respond to Questions 5 and 6.
