Students learn how to manipulate the various formulae associated to the area of a sector and arc length to find the radius and angle theta.  As learning progresses they are challenged to solve more complex problems both with and without a calculator.

Differentiated Learning Objectives

• All students should be able to manipulate the formula for the arc length of a sector.
• Most students should be able to manipulate the formula for the arc length and area of sectors.
• Some students should be able to derive known facts for problems involving sectors through manipulating the formulae.
