Instructional Ideas

  • Use as an introduction to linear systems
  • Extend example one by asking how the graph would change if one person was walking faster or slower and how it affects the intersection point
  • Write a description about each intersection point using context and specific units and measures
Classroom Considerations

  • Using stairs may reinforce the common misconception that a line with a negative slope means a person is walking downhill; front load the concept of a distance vs. time graph to rectify this problem
Pros

  • Well-designed lesson with introduction and conclusion activity
  • All handouts and keys are included
Cons

  • None
