Good Cop, Bad Cop

How should cities address excessive force by police? Students compare two distributions of complaints against police officers. They analyze the fraction of complaints that officers are responsible for and evaluate the effectiveness of policy proposals in each scenario.

Distributive Properties

Have income distributions in the U.S. improved over time? Students compare percentages of total income earned by different subgroups of the working population and decide whether or not the “American Dream” is equally achievable by all Americans.

Prescripted

How should pharmaceutical companies decide what to develop? In this lesson, students use linear and quadratic functions to explore how much pharmaceutical companies expect to make from different drugs, and discuss ways to incentivize companies to develop medications that are more valuable to society.

You're So Fined

How long does it take to pay off municipal fines? Students use linear equations and solve linear systems to examine what happens when people are unable to pay small municipal fines. They also discuss what can happen to the most financially vulnerable citizens when cities rely heavily on fines for revenue.

Common Cents

How much is money worth? Students apply operations on rational and decimal numbers to calculate how much the U.S. Mint spends on different coins, and discuss whether we really need all these coins.
