7-3.4 Applying Circumference (Alternative)

This is a pretty straight forward adaptation of the OUR lesson. I don't have the grasshopper jumping off the wind turbine yet. Lesson Narrative and Goals from OUR: --I can choose an approximation for π based on the situation or problem. --If I know the radius, diameter, or circumference of a circle, I can find the other two. In this lesson, students use the equation  to solve problems in a variety of contexts. They compute the circumference of circles and parts of circles given diameter or radius, and vice versa. Students develop flexibility using the relationships between diameter, radius, and circumference rather than memorizing a variety of formulas. Understanding the equation  will help with the transition to the study of area in future lessons. Students think strategically about how to decompose and recompose complex shapes (MP7) and need to choose an appropriate level of precision for  and for their final calculations (MP6).
