This teaching aid is designed to demonstrate that the area of a circle is equal to the area of a rectangle using a simple visual and hands-on method. Made from durable foam with a magnetic backing, it can be easily used on a magnetic board for classroom demonstrations. The circle, with a diameter of 28 cm, is divided into 16 equal parts that can be rearranged to form a rectangular shape. This helps students clearly understand the concept of area equivalence in an interactive and effective way.
