Slopes are everywhere—even in houses! Given a picture of a house, learners find lines with positive, negative, zero, and no slopes. Scholars determine the equation of the lines by calculating the slopes and y-intercepts. Class members then find pictures of real-world objects that have the four different types of slopes.

Instructional Ideas

• Provide several magazines with pictures to use to find images of slopes

Classroom Considerations

• Assumes the class understands how to write equations of a line given a graph
• Requires the ability to overlay a coordinate axis over an image

Pros

• Provides a sample solution
• Includes suggestions for teacher questions to determine whether pupils understand the material

Cons

• None
