This activity is unique because it can be used as a worksheet with 48 questions, an individual game. It can also be used as a game for 2 students, a game for 4 students or a game that the students can take home and play with their family.
When this is played 2 students against 2 students, it uses cooperative learning between students on the same team and competition between teams. I find this mix a great combination for the students to feel safe, yet have some fun! It can be differentiated by grouping students of like ability against other students of similar ability. To add a tournament aspect, after 30 minutes call TIME. I have the student team names up on the board, and they indicate who won by putting a check mark next to their team. Then, I pair up new teams. I will pair up 2 teams of similar ability again for the winning teams, then do the same for the losing teams. Then, they have another 20 minutes to play, and the winners of the last round of the tournament are the tournament winners !
To increase accountability and to ensure the students have a written record of their work, I have them complete the solutions on a piece of paper, or I have the students do the work in their math “scribblers” that they use when they do these kinds of activities. I collect the work at the end of the period and mark it.
Also, it is noteworthy to mention that it is useful to talk about being a good winner and loser. The act of spelling out the expectations can prevent any problems during the activity.
