The Discerning Digits Activity is similar to the Discarding Digits Activity that I created. However, it is more challenging because the students have to ensure that digits are placed correctly relative to the other digits in the same row and same column. Consequently, some of my students prefer this game to the Discarding Digits game.
• Student Activity: Discerning Digits (2 pages), 1 copy per student
• A single random number generated to be used by the instructor
Through the choices that they have to make in this activity, students have the opportunity to experiment with different strategies while they observe the outcomes of this probability game. Since each game takes approximately five minutes to complete, students may revise their strategies as they play additional games throughout the class period.
When this activity is completed, an examination of different strategies, and student rationales for using them, can lead to an interesting class discussion.
