Calvin's Trinkets

Published on 09/10/2009

Activity Overview

This activity simulated the purchase of cereal boxes in order to get a "complete set of all ten colors" of plastic trinkets. Students will record data in a tally chart in order to find the number of boxes purchased in each instance of successful completion of a set. Collecting and analyzing class results will allow them to examine descriptive statistics like range, minimum, maximum, and mean.

During the Activity

Students will use the randInt function in order to generate random numbers from 1 to 10. After completing one set of ten colors, they will use the LIST feature of the calculator to "purchase" several sets of 50 boxes.

When each student has several data points, they will enter the class data into a collective list. This will allow students to arrive at an experimental answer to the question of how many boxes must be purchased.
