The WHY behind Area of a Circle

In Mathematics this week, we have continued our study of the measurement strand.

The Pythagoras Group has been looking specifically at:
Perimeter and area of a: square, rectangle, triangle and circle (circumference)
Volume of a: cube, rectangular prism, triangular prism, cylinder and cone

The Pythagoras group has been learning Karate Maths to help them remember the formulas for each (ask your child to demonstrate!).  It is important however, that we understand the WHY for each... this is not so easy!

Below is a video that helps to explain the WHY behind the area of a circle.  Check it out!
