      About This Lesson

      Go to www.21stCenturyLessons.org for unit sequencing; Lesson Objectives: Students will be able to describe the formula for the area of any circle in the world. Students will engage in a hands-on activity that allows for them to discover that it takes a little more than 3 "radius squares" to find the area of a circle. The lesson utilizes a short video to solidify the relationship while maintaining a hands-on experience. The lesson begins with a warm-up which you can build on as the class progresses. Aligned with CCSS: 6.G.1 , 6.G.4 , 7.G.4
