Lesson Plan: Piecewise Functions Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify, write, and evaluate a piecewise function.


Students will be able to

  • recall the definition of a piecewise function,
  • understand the notation and graphs of piecewise functions,
  • evaluate a piecewise function using its equation,
  • evaluate a piecewise function using its graph.


Students should already be familiar with

  • open and closed dots on a graph.


Students will not cover

  • drawing graphs of piecewise functions,
  • the domain and range of a piecewise function.
