## Slope and Grade

In this lesson students learn how to use the slope formula to calculate steepness. In particular, students learn how to calculate steepness in the context of cycling. Cyclists use a measure called *grade* to calculate the steepness of a hill or mountain. Students apply their knowledge of slope to the concept of grade.
