Instructional Ideas

  • Have learners brainstorm contexts for a given graph in a journal entry
Classroom Considerations

  • Lesson uses piecewise linear functions, but does not define piecewise functions
  • Graphs including nonlinear functions show up in the next lesson
Pros

  • Professional-looking graphs
  • Situations involve a variety of contexts that allow pupils to see importance of mathematics
Cons

  • None
