Unit 3, Lesson 10# Distinguishing Circumference and Area

Open Up Resources 50 min(s)

In this lesson, both types of problems are mixed together so students have to distinguish which measurement is called for in each problem situation. Also, in previous lessons students were always given one measurement of each circle, but in this lesson they must rely on their own estimations to solve the problems. Let's contrast circumference and area. Learning targets: students can decide whether a situation about a circle has to do with area or circumference.
