Seeking Shelter

How is homelessness changing in the United States? Students write linear equations to describe how the number of people experiencing homelessness has changed in different cities and use their equations to predict how those populations will grow in the future.

Ad Vantage

How much of what we see is advertising? Students decompose irregular shapes to find how much of their visual field is occupied by advertising in real life and online.

Fall of Javert

Could Inspector Javert have survived the fall? Students use quadratic models to determine how high the bridge was in Les Misérables, and explore the maximum height from which someone can safely jump.

Downside Up

Is there an upside to negative feelings? Students use integers to compare good and bad days and use absolute value to explore what happens when we reinterpret negative moments in a more positive light.

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.

Pizza Pi (HS)

Which size pizza should you order? Students apply the area of a circle formula to write linear and quadratic formulas that measure how much of a pizza is actually pizza, and how much is crust.

Three Shots

In basketball, should you ever foul at the buzzer? Students use probabilities to determine when the defense should foul...and when they should not.

My Fellow Americans

Have presidential speeches gotten dumber? Students evaluate the Flesch-Kincaid formula with inputs from three different presidents and analyze the formula to predict how specific changes to a speech will impact its score.

Ballot Boxing

How do the rules of an election affect who wins? Students calculate (as a percent) how much of the electoral and popular vote different presidential candidates have received, and add with integers to explore elections under possible alternative voting systems.
