Application of Slopes

Published on 07/01/2010

Activity Overview

Students will apply the concept of slope to a real-world problem about building a staircase. They will use the slope ratio, vertical change over horizontal change, to find the slope of staircase. Then, students will recognize how a positive or negative slope applies in a real-world situation.

Key Steps

    Use the Slope tool (MENU > Measurement > Slope) to find the slope of the staircase (segment AB). Then have students answer questions such as the following.
    How does this slope compare to the building code requirement? How does the staircase need to change to meet the slope requirement?
