This lesson is great for introducing normal distributions as well as the difference between expected/theoretical distributions and reality. Give students pairs of dice and have them record values in DataFly as they roll. What does the distribution of the chart look like after each student has done one roll? How does it compare to an expected distribution? What happens after 2 rolls per student…5…10? Note: be sure to enable multiple entries from a single device!

Question 1: What number did you roll?
