This resource includes multi-part word problems that focus on using a quadratic model to analyze questions in context. In each of these problems, students calculate and interpret key features of quadratic functions (axis of symmetry, vertex, y-intercept, x-intercepts) based on a real world context. They can factor for the first problem, but will need the quadratic formula for the second two. There are three total problems, and the data for each is genuine!
Good to know
* You can use each problem as a guided, learn-by-doing
way to build students’ skills or as group / independent practice
. The learn-by-doing approach could take most of a period for each problem, while the group / independent practice approach should take just 10-20 minutes.
* Each problem is on separate pages, so you can use each one when most appropriate for your unit. Just print and go
* This is a Word document
, so you’ll have the power to adjust, add, or delete any questions to meet the needs of your class. (If you need a PDF version, I’d be happy to give you one. Just e-mail me at firstname.lastname@example.org.)
Problem 1: Happiness vs. the Cheeseburger. Students explore how much happier people get when they eat cheeseburgers… and how too much of a good thing can bring us down.
Problem 2: The Hail Mary. Students take on the role of a quarterback and filmographer, trying to figure out how much time they need to wait before throwing the pass and how to catch it all on camera. (There’s a link to a great, quick video for this one!)
Problem 3: Pokémon Go. Students explore the rise and fall of the game Pokémon Go. They take on the role of a game designer, determining exactly how to make it more popular.
