On February 3, 2012, Mrs. Sorrell’s class had an enrichment activity that involved circles – the area, the radius, circumference, diameter, chord, etc. We also had planned to cook donuts, since they were circular in shape.
The lesson began with an introduction to circles. We talked about pi, and its significance in math (especially when dealing with circles). We went over the basic vocabulary in geometry, such as chord, diameter, radius, circumference, and area, and discussed what they are and the formulas to find and/or calculate them. For instance, we went over the formula to find the area and circumference, which is πr2 and 2πr, respectively.
After learning a bit about the basic facts of circles and how to calculate dimensions of circles, we began the process of cooking the doughnuts. After all of the students had each gotten a doughnut (or two), Stephanie began reading a book titled Sir Cumference and the First Round Table by Cindy Neuschwander and Wayne Geehan.
As our enrichment time came to an end, various students volunteered to take extra doughnuts to Mrs. Richards, Mrs. Kelley, Mrs. O’Neal, Mrs. Scott, and Mrs. Krause. The doughnut lab provided a fun, educational experience for all of the students in Mrs. Sorrell’s class.
