Introduction to Module 2.2: Perimeter and Area

In this module you will see how two teachers take different approaches to solving the motivating CAHSEE question. While their student populations are very different, both teachers achieve success by activating prior knowledge, acknowledging different learning styles, and having a keen awareness of their students' social needs.

Let's see what this multi-faceted problem looks like.

The motivating CAHSEE release question for this unit is the following:

The largest possible circle is to be cut from a 10-foot square board. What will be the approximate area, in square feet, of the remaining board (shaded region)? (A = Pi(r 2) and Pi » 3.14)

A. 20
B. 30
C. 50
D. 80
