Last Monday, on 3.14, 5th grade students in Ms. Bolte's class dove into an exploration of circles to celebrate Pi Day. The students used beans and counters to measure the distance around (circumference) and across (diameter) circles. They then analyzed the ratio of their measurements of circumference to diameter to discover the value of pi.
In between counting and measuring, the students' discussion centered on their curiosity in how ancient peoples knew of and used this ratio long before the number pi officially existed. The best part of the day was the circular pi day cookies to celebrate!
