 Learning Target:

I can determine an arc length. I can determine the area of a sector.

Success Criteria:

I can convert an angle in degrees to radians.

I can convert an angle from radians to rotations.

I can convert units of measure.

Introduction/Connection: 

Connection – The diameter of a bicycle wheel and the number of rotations the tire makes gives you the distance traveled.

Do now  -SAT/ACT Practice- students will answer multiple choice questions written in the SAT or ACT style – posted in Google Classroom

DIRECT INSTRUCTION:

I will connect arc length and area of a sector formulas to the proportions used in Geometry.  I will demonstrate how to use arc length and area of a sector formulas are used to solve several types of problems using the Arc length/ Area of a Sector power point.(Located in Google Classroom)

Work Period  (We Do, You Do)

Students learning by doing/demonstrating learning expectations.  Describe the instructional process that will be used to engage the students in the work period.
