Activity Overview

In this activity, students explore how to write and enter a calculator program that will simulate coin tossing for a given number of times and count the number of heads and tails. They analyze the program and modify it.

Before the Activity

  • Set the calculator in Alpha mode
  • See the attached PDF file for detailed instructions for this activity
  • Print pages 51 ? 59 from the attached PDF file for your class
  • During the Activity

    Distribute the pages to the class.

    Follow the Activity procedures:

  • Set up the calculator to accept a new program
  • Enter a name for the program
  • Enter the program commands; setting a prompt that allows the user to enter the number of coin tosses to be simulated and a pause that allows the user to view the result after each coin toss
  • Run the program on the calculator and enter the number of trials
  • Analyze the data generated by the program
  • Predict the consequences of removing the Pause command from the program code
  • Delete the Pause command from the program
  • Run the program again, and check the prediction
  • Edit the program to include the count of heads and tails in the coin toss simulation
  • Observe that the program allows one to conduct the simulation many times, quickly, and displays the results for analysis
  • After the Activity

    Students answer the questions.

    Review student results:

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