After students have learned about basic exponential functions, this activity can be used to test understand of transformations of exponential equations.
Before the Activity
If you are using the TI-Navigator System with the TI-73 you will need the attached .pdf file.
Students should know basic exponential functions and how to transform them.
During the Activity
Show the tower in the Activity Center. Have students send an exponential equation to see if they can trace the left side of the tower. Class discussion should follow. Now have students try to trace the right side of the tower. This is a much more challenging task. Class discussion should follow.
After the Activity
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
