9 Spring 2 Lesson 3

This activity is an explicit follow up to Polygraph: Parabolas. It uses the context of the game by asking students to interpret questions from fictional players over several iterations. In each iteration, students learn the formal term for the property and then sketch a parabola where this property is used as a constraint.

The Venn diagram activity idea was taken from the MrBartonMaths website. These are used in various places through the scheme.

Objective Identify important features of parabolas and use them to sketch quadratics.
