Instructional Ideas

  • Ask learners to record the information described in a graphic organizer; they should note the definition, an example, and a non-example
  • Can be used as a flipped classroom assignment with the video assigned as homework and the practice problems completed in class
Classroom Considerations

  • Pupils should understand the concept of a function prior to the lesson
  • Requires Internet access to watch the YouTube video in class or at home
  • The twenty-first installment in a series of 29 videos
Pros

  • Focuses on algebraic methods but also makes a connection to the graph of the function
Cons

  • Includes only a weak explanation of what a one-to-one function is and doesn't explain its importance
