Instructional Ideas
  • Have the class work a few example problems using the algebraic relationship between exponential and logarithmic functions prior to handing out homework
  • Before beginning the activity, find inverses of other simpler functions using a table and graph
Classroom Considerations
  • Class familiarity with graphing calculators is beneficial
  • Though it is anticipated that the graphs of the exponential and logarithmic function will lead to the understanding that they are inverses, more direct guidance may be needed
  • UDL checklist is provided for this specific lesson
  • Answers are given for the activity
  • The teacher notes where to look for the different math practices during the lesson
  • None
