Modeling Data
Materials:
two different-colored dice, colored pencils, grid paper, scissors, tape
If you completed the first activity, you made a graph displaying the sums
of two dice that you rolled. In the second activity, you will examine the
various ways that sums can be rolled for two dice.
Collect the Data
Step 1
Get the two dice. Notice that the only way to get a sum of 2 is
roll a 1 and a 1. You can get a sum of 3 in two ways. The red die
can be a 1 and the green die can be a 2 and the red die can be a
2 and the green die a 1. Complete the table below by examining
the various ways to make each sum.
Sum of Dice Ways to Make the Sum Frequency
