Approximating Pie in Geogebra is a great technological resource to use in a high school math classroom. This particular method is known as "Archimedes method of approximating pie". This method involves approximating pieby the perimeters of polygons inscribed and circumscribed about a given circle. Throughout this activity, students will use the resources provided to them in Geogebra to look at a circle as a series of regular polygons inscribed in a circle with an increasing number of sides. By doing this, students can approximate pie.
