Lessons in Units

CCSS UnitsHow should police departments address excessive use of force? Students compare the distributions of excessive force of two police departments and explore how the shape of the distribution affects the effectiveness of different solution attempts.

Is there an upside to having a bad day? Students use positive integers, negative integers, and absolute value to describe the emotions of a day and discuss the important role that different emotions play in our lives.

How much Halloween candy should you eat? Students analyze graphs of linear and nonlinear piecewise functions to compare how much enjoyment people get as they eat through their candy and debate the best strategy for maximizing Halloween happiness.

What time should school start in the morning? Students use periodic functions to compare the alertness levels of adults vs. teenagers over the course of the day and debate the merits of starting school later.

How do viruses spread through a population? Students use exponential growth and logarithms to model how a virus spreads through a population and evaluate how various factors influence the speed and scope of an outbreak.

How do vehicles turn so smoothly? Students calculate the circumferences of circles to determine how far vehicles travel during a turn and explore the engineering that allows cars to turn so smoothly.

Is it a good idea to rent a storage unit? Students write and solve multi-step equations to evaluate whether storage unit rentals are worth the cost and make recommendations for when people should store, sell, donate, or toss their unused stuff.

Are hybrid cars worth the extra cost? Students use linear equations to compare the costs of driving a car with a standard engine versus a hybrid engine and debate whether new buyers should always go green

Who should win extreme weight loss competitions? Students use linear functions and lines-of-best-fit to predict results from Season 8 of The Biggest Loser and discuss whether such examples of extreme weight loss are realistic and sustainable.

How much would it cost to get all the toys in a Happy Meal? Students use trials, probabilities, and expected value to determine how many meals it takes to get a complete set of Happy Meal toys and debate whether McDonald’s should allow customers to pay a fee to choose their own figurine.

How much should you trust your memory? Students use exponential decay to model memory fidelity and debate whether a bad memory is a good thing.

Should the U.S. get rid of the penny? Students operate with decimals to calculate the total costs to produce different U.S. coins. Students debate eliminating the penny and then consider a world with no physical money at all.

How much should you bid in an auction? Students create polynomial functions to model the expected value of a given bid and determine the optimal amount someone should bid in any auction.

Should airlines overbook their flights? Students use compound probability and expected value to determine the optimal number of tickets an airline should sell and discuss whether airlines should be allowed to overbook their flights.

How should pro sports teams spend their money? Students use linear regressions and r-squared values to analyze data from professional sports leagues, evaluate how various factors correlate with wins, and debate whether a higher payroll is good business strategy.
