Covariational Reasoning Lesson 4

Culmination of the N-Gon Tasks

Zoe and Gisele work to describe what happens to a polygon, and its related graph, when the number of sides goes to infinity.

Episode 1: Making Sense

In this episode, Zoe and Gisele make sense of an infinite sided polygon.

Episode 2: Exploring

Zoe and Gisele construct a graph that relates the height of a point, A, as a function of its distance traveled as A travels counterclockwise around a circle.

Episode 3: Exploring

The students work to describe how they know their graph accurately captures the relationship between height and distance.

Episode 4: Reflecting

Zoe and Gisele hone their language about the change that is happening continuously for the simultaneously varying quantities of height and distance.
