Reflection: Diverse Entry Points Constructing an Argument for the Circumference Formula - Section 1: Scaffolded Argument

 

In order to know what function to find the limit of, and to predict that the limit of that function should be pi, students will need to do some analysis of structure. Check out the following screencast to see how I help students to develop the ability to see structure.

Constructing an Argument for the Circumference Formula

Unit 11: Measurement and Dimension
Lesson 1 of 6

Objective: SWBAT construct a semi-formal argument to establish that the circumference of a circle is 2(pi)r

Big Idea: Circular Argument? In this lesson, students use structural analysis, trigonometry, and limits to show that the circumference of a circle is twice the product of pi and the radius.
