What activities in this unit helped you learn a new math concept? Explain the activity, your new learning (be specific!) and provide a snapshot of the work.

In Unit 3, we learnt about Geometry. In one part, we did an investigation about finding the area of a circle. We used four different methods in the investigation: the Curvy Parallelogram, the Egyptian Method, and Beans. All of these methods have very close answers to each other and the original answers. The Curvy Parallelogram is most efficient of all methods in my opinion because since I know how to calculate the area of a parallelogram, it is an advantage to calculate it.
