During the Activity

Teacher should set activity center to contribute points and configure to submit at least two points depending on the number of students in class.

You will then have students submit points to reflect the image on the right (roller coaster).

As a side note, the teacher may wish to experiment with the window settings.

As the students progress, you may have them submit equations (quadratics, trigonometric functions) to model the image on the screen.

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
