Mathalicious: New-Tritional Info

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.
