Background For Teachers:
Ways to Gain/Maintain Attention (Primacy):
Segment 1: How can we construct a histogram? When is a histogram suitable for representing data? How can a histogram help us find central tendency? What can we infer from the data?
We are going to construct a histogram showing the amount of pocket change we carry in this class. Read the directions to the Pocket Change worksheet with the class. Draw the numberline on the board and give each student a post-it note. Follow the directions on the worksheet to help students construct a histogram for the class data.
Save the data from another class so students can compare.
Lesson Segment 2: How would the data look if another type of representation were used?
Both a histogram and box and whisker plot are useful for displaying large data sets (T)
Have students use the data they have entered in their calculators to construct a box and whisker plot and compare both types of plots. You may want to break the data into pocket change for girls and pocket change for boys to construct two histograms to compare or to construct two box and whisker plots to compare.
