How can we improve our calendar? Students examine some other ways to keep track of dates, and use number sense and function concepts to convert among different calendars.
Can you predict a country's Winter Olympic performance? Students analyze scatterplots and correlation coefficients to pick out the best predictive model for Olympic success.
What are some ways to encrypt secret messages? Students use ciphers to encrypt messages both graphically and algebraically, and try to decrypt some messages too. In the end, they’ll learn what makes for a useful cipher, and what makes a cipher impossible to decode.
How fast does hair grow? Students analyze a scatter plot, create a line of best fit, and interpret slope as the rate of hair growth over time.
How dangerous is texting and driving? Students use proportional reasoning to determine how far a car travels in the time it takes to send a message, and explore the consequences of distracted driving.
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 symmetrical are faces? Students apply their understanding of line reflections to develop a metric for facial symmetry.
How has the iPod depreciated over time? Students will compare linear and exponential decay, explore how various products have depreciated, and what might account for the differences.
How hard should you exercise? Students write and graph an equation for maximum heart rate in terms of age, and then calculate ideal heart rate zones for different types of workouts.
How much should vowels cost on Wheel of Fortune? Students use ratios and percents to explore what would happen if Wheel of Fortune charged prices for vowels based on how often they come up.
Have presidential speeches gotten dumber? Students will evaluate the Flesch-Kincaid formula with inputs from three different presidents and will analyze the formula to predict how specific changes to a speech will impact the score.
Did UC Berkeley discriminate against women? Students use frequency tables, conditional probability, and Simpson's Paradox to explore the (un?)fairness of college admissions.
What's the optimal bidding strategy in an auction? Students use probability, expected value, and polynomial functions to develop a profit-maximizing bidding strategy.
How much can you trust your memory? Students will construct and compare linear and exponential models to explore how much a memory degrades every time they remember it.
How does the media 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 media influences our experience of the world.
