Unit 8: Circles and composite figures

1,100 possible mastery points

About this unit

We've built the idea of area by filling rectangles with unit squares. Then we sliced and slid them to form other shapes. But how would we find the area of a circle, which we could keep filling with smaller and smaller rectangles forever without every finishing? We'll find the area and the circumference (like perimeter, but rounded) of circles and other complicated shapes.
