Activity Overview
Students extend their understanding of theoretical probability and patterns. They use number cubes, to build awareness that a fraction and its decimal and percent representation on the calculator are "close," but not necessarily equal.
Before the Activity
See the attached PDF file for detailed instructions for this activity
Print student activity sheet page 121 from the attached PDF for your class
During the Activity
Distribute the page to the class.
Follow the activity procedures:
Roll two number cubes and represent the results as fractions, decimals, and percents
Examine the experimental probabilities
Record all the ways of rolling two number cubes to get each possible sum of 2 through 12
Record the theoretical probability of each sum in fraction, decimal, and percent
Understand what the numerator and denominator used in the calculation represent
Investigate the sum of all the fractional probabilities, the sum of all the decimal representations, and the sum of all the percents
Analyze the results
After the Activity
Review student results
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
