Unit Rate Comparisons & POW: Mean & Median

LARGE GROUPS
Today we heard more Stretching & Shrinking Unit Project presentations, and we discussed the POW: Flags. Then we talked about how to calculate mean and median, two measures of center that allow us to analyze data. The POW this week is called Mean and Median, and can be downloaded here.

Finally, we worked on Problem 3.3, Comparing CD prices, where we calculated unit rates (price per CD) and wrote equations for different situations, including tax or shipping fees.
