Today, I co-taught with the calculus teacher transforming of trigonometry functions. I simply introduced the equation, keyboard, and graphing features of the Free Graphing Calculator app while the content teacher taught the specific details of the concept.
During the first class, I performed most of the iPad functions. During the second class the content teacher proceeded with most of the iPad functions. Now, he can use the iPads with the graphing calculator app without me being present in the room.
It was truly a fantastic co-teaching experience.
