Probability | Activity 10: Give Me Five 57 |
10.Discuss with students:
How many total trials did you and your partner have?
Raise your hand if you had a
Which score on a single trial would you predict is more likely to occur, 0 or 5?
Out of the 50 trials, how many trials would you predict to be worth 5 points?
11.Record group data in the
To calculate the probability, use:
# of times event occurred / total # of trials
12.Add the probability column, and then discuss why the sum is 1.
13.Convert the probability fraction to decimal form using the > key. Record this in the decimal column of the Small Group Data table.
14.Ask students:
How do the probabilities between your group and other groups compare?
Does one outcome seem to be more probable than others?
Is one less probable?
15.Collect the class data and have students record it in the Class Data table.
16.Enter the class data into the

Students should record probabilities as unsimplified fractions and also in simplest fractional form. Verify the total number of trials as 50 by adding the frequency column.
In the student pairs, have Student A call out frequencies for points on each roll while Student B keeps a running total of the frequencies either mentally or with the
