Polygons and Pi - A Geogebra Activity
The image seen on your left, is a screenshot from an interactive geometry, algebra, statistics and calculus application called "Geogebra". The activity that I put together, which can be accessed by the link below, was called "Polygons and Pi". It involves an interactive lesson through the use of this application, and step-by-step instructions to inscribe a regular polygon with "n" amount of sides inside a circle with a radius of one. A slider was involved with the construction of the regular polygon that enabled the adjusting of the amount of "n" sides the polygon contained. The discovery learning involved in this activity was seen through the associated areas of the circle and the regular polygon inscribed in it. The area of a circle with radius of one means that its area is equal to pi, therefore as the amount of "n" sides increased and created a polygon closer and closer to the circle, the closer the corresponding areas were to one another, pi.
This application is a free product that enables many teachers to provide students with a different form of technology to learn and use when teaching a lesson. It contains many features to help articulate the different studies within mathematics and can serve as a great tool within the classroom. Technology is such an emphasis in teaching today, with differentiated instruction, the availability of programs such as this one makes it easily accessible to download and start using right away. I personally enjoyed using this program and completing this activity, due to it was different then anything that I have used before and challenged me to learn the different functions to complete my lesson I had planned.
