Graphing Calculator Activities for Enriching Middle School Mathematics

Collecting Pens (Continued)

Activity Overview

In this activity, students learn how to instruct the calculator to collect and organize the results from several trials of a simulation designed to find out how many boxes of cereals a customer would have to buy to collect all six color pens. Students enter a prewritten program, analyze the results of the simulation from the summary statistics and statistical plots.

Before the Activity

• Study the program code and its explanation
• See the attached PDF file for detailed instructions for this activity
• Print pages 77 - 86 from the attached PDF file for your class
• During the Activity

Distribute the pages to the class.

• Run the program, and enter the number of trials [≤ 99]
• Observe the random numbers generated by the program, and understand that the program stores the data as a list
• Sort the data in ascending order, record the minimum and maximum values, and determine the range
• Produce and examine a list of statistics summarizing the information
• Set up a histogram
• Graph a box-and-whisker plot
• Analyze the distribution of the data
• After the Activity

Students complete the Questions sheet.

Review student results:

• As a class, discuss questions that appeared to be more challenging
• Re-teach concepts as necessary
