Real World Applications & Pi

Today, fourth grade students took a measure of yarn and made varying size circles. Then, they cut three more pieces of yarn to represent the diameter of each circle. Students used the yarn (diameter of each circle) to measure its circumference. After finding that each circle’s circumference measured just a bit more than three of its diameter, students came to the conclusion that this would be true for all circles. Today’s hands-on Pi activity helped students better understand diameter and circumference. It also helped them better see the connection to pi=3.14. tlb
