Should fast food restaurants rewrite their menus in terms of exercise? According to the McDonald’s menu, a Big Mac contains 540 calories. But what does that really mean...and would it be more helpful to describe this as “65 minutes of running”?

In this lesson, students write and evaluate expressions to determine how long it takes to burn off foods from McDonald’s and debate the pros and cons of including this information on fast food menus.

Students will

  • Use rate and ratio reasoning to solve real-world problems
  • (Optional) Write and solve on-step equations to determine how much exercise would be needed to burn of different food items.

Before you begin

Students should understand what a unit rate is; if they have experience calculating and using unit rates to solve problems, even better.
