Grab Bag Lesson Class: Eighth Grade Mathematics Instructor: Mr. Vogel Unit: Probability and Statistics Time: 1 Period (68 Minutes)
Do Now • How do you calculate the mean, median, and mode for a set of numbers? • What is the mean, the median, and the mode for the set of the following girl’s shoe sizes: {4, 5, 5, 5, 5, 5, 5, 6, 6.5, 6.5, 7, 8, 9}?
Grab Bag Activity Discussion Questions • Which measure (median, mode, or mean) best represents the typical length of a rod from a handful of Cuisenaire Rods? Explain your reasoning. • What does the mode tell you about the handful? Why is the mode sometimes very different from the mean and median? • What does the median tell you about the handful of rods? • How is the mean useful in describing the typical length of a rod? • Which set of data (Player 1, Player 2, or the combined totals) is most useful in describing the typical length of a rod? Why?
Grab Bag Activity Extension Discussion Questions • How did you go about making your predictions? • How did the data that you collected compare to your predications? • Compare your data to that gathered during the first activity. Which measure—the mean, the median, or the mode—was affected the most by the removal of the Cuisenaire Rods? Why?
Closure • What did you learn from this lesson?
