Circle graphs, or pie charts, are a common way that data is represented not only in math but in other content areas as well and in our daily lives beyond the classroom. For this reason, it is important that students understand how this graphical representation works. In "Paper Plate Pie Charts", you will learn how students can easily engage in conducting surveys and represent the data on a pie chart. Minimal materials and the concept of self-assessment make this an easy and effective activity for you as the teacher.
