Lessons in Units

CCSS UnitsWhich 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.

Should you ever order a personal-sized pizza from Pizza Hut? Students calculate circle areas to compare the unit costs of different sized pizzas, find the percent of pizza that is tasty inside vs. crust, and debate whether it’s ever a good idea to order a personal-sized pizza from Pizza Hut.

How much is Domino’s really charging for pizza? Students use slope, y-intercept, and linear equations to explore the costs of different-sized pizzas at Domino’s and debate whether the pizza chain should be more transparent in its pricing.

Are Papa John's specialty pizzas a good deal? Students evaluate expressions to compare the prices of specialty vs. build-your-own pizzas, and determine how much they're saving...or losing!
