Slope and Grade

Description

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.

Student learn to use the slope formula and then apply it to the context of grade. Several instructional videos provide the background on using the slope formula. Examples of using the slope formula are then provided.

Assessments include two drag-and-drop activities that call on students to carefully analyze the use of the slope formula.
