Lesson Name: Probability Models--Internet
TEKS: 8.11C
Technology TEKS: 1A, 7H, 7J
Objective: The students explore the relationship between theoretical and experimental
probabilities using the interactive tool “box model”, a statistical device that can be used
to simulate standard probability experiments such as flipping a coin or rolling a die.
Process:
 The teacher will need to review the activity at
http://illuminations.nctm.org/LessonDetail.aspx?ID=L448 and provide a link for
the students to access the activity.
 Students will simulate the relationship of tossing a coin (place the 1 and 2 into the
box model) and will compare the theoretical outcome by clicking in the Show
theoretical outcome box. What is the effect of the number of “tosses” of the coin
on the actual outcome versus the theoretical?
 Students will simulate the relationship of rolling a die (place numbers 1-6 into the
box model) and will compare the theoretical outcome by clicking in the Show
theoretical outcome box. What is the effect of the number of “rolls” of the die on
the actual outcome versus the theoretical?
