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

Pros

• 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

Cons

• None
