Reflection: Modeling Constructing an Argument for the Circumference Formula - Section 2: Transfer Task


This was one of the more rigorous lessons in the course. Many students complained that it was too difficult. However, it was an honors class and I felt the level of rigor was at the upper range of appropriate. I noticed that many students tended to take solace in finding out that one of their peers didn't understand or was struggling. They seemed to take this as validation that the task was beyond their abilities. So I decided to show students work their classmates had actually done. This way, it wouldn't be seen as so far fetched that they too, with hard work, could achieve similar results.

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.
