How big is the White House? Students build scale models of the White House, compare scaling in one vs. two vs. three dimensions and design their ideal version of the president’s house.
How is wealth distributed in the United States? Students use measures of center, five-number summaries, and box plots to examine different distributions while digging into one of the most important economic and political issues facing any nation.
How does the what we see affect our happiness? Students explore the concept of the jen ratio – the ratio of positive to negative observations in our daily lives – and use it to discuss how the content we consume and the things we observe influence our experience of the world.
How long does it take to burn off food from McDonald's? Students use unit rates and proportional reasoning to determine how long they'd have to exercise to burn off different McDonald's menu items.
How should we tip in a restaurant? Students use mental math, percents, and proportional reasoning to compare different approaches to tipping.
How much do different professionals earn in a year? Students use rates and ratio reasoning to compare how much a teacher, the President, and LeBron James earn...and to compare how much value the create.
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.
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.
What's the best way to bet on the Super Bowl? Students add and subtract positive and negative numbers to determine which bets have been the most effective and consider the best ways to win big on the big game.
How were free states and slave states represented in Congress? In this lesson, students use census data and fraction multiplication to explore the effects of the Three-Fifths Compromise on the balance of power between free and slave states in early America.
How should grades be calculated? Students use averages and weighted means to examine some different grading schemes and decide what other factors ought to be considered when teachers assign grades.
How can we compare similar items? Students plot points with positive and negative coordinates in order to compare items across two different attributes. They use the plots to decide which item is the “best” in different scenarios, and discuss whether or not negative numbers always represent the “opposite” of positive numbers.
Should shoe companies sell left and right shoes separately? Students collect survey and measurement data, construct bar graphs, and discuss distributions and measures of central tendency in order to figure out whether shoe companies should necessarily be selling their products in same-size pairs.
What's the best way to design a food tray? Students calculate the volumes of rectangular prisms and use that information to design a cafeteria tray that looks good and holds a balanced meal.
How much should people pay for cable? Students interpret scatterplots and calculate the costs and revenues for consumers and providers under both the bundled and à la carte pricing schemes to determine which would be better for U.S. companies and customers.
