The idea was simple: students stacked the cookies to make a tower. They collected data on how tall their towers got and then used that data to practice data management such as mean, median, mode, and range. We also made it into a line graph! The basic rules were that they couldn’t hold it to make it stay up while they were stacking and once one cookie fell they had to start over.
I had five teams and they did three rounds of stacking each in our competition. We even had a bonus round where they were allowed to hold up their towers! After each round, the team leaders were responsible for adding their team’s data to the board. At the end of the competition, they had to analyze the data to find the mean, median, mode, and range of their data and then of the class’ data. Finally, they had to make a double line graph to show the data. They LOVED this activity!
