Using circles printed on card stock and string or twine, students glue diameters to the edges of the circles and discover how many diameters it takes to completely encircle the figure. Supplemental activities, formulas for circles, group questionnaire, teacher evaluation, time-saving tips and tips for learning differences are all included. This project can be completed in one class period and is suitable for elementary grades through high school. Any supplemental activities completed would require additional time.
