It’s almost Pi Day!
Pi is an irrational number that represents the ratio of every circle’s circumference to its diameter. Although the digits of pi never repeat and never end, we often use 3.14 as the approximate value of pi. To honor this special constant, mathematicians and educators all around the world have set aside March 14th as the day to celebrate all things pi, hosting pie eating contests and pi-related activities. The celebrations have become more elaborate each year, and in 2009 the U.S. House of Representatives passed resolution HRES 224 recognizing March 14th as National Pi Day.
Join Sylvan Learning in celebrating Pi Day with your family and friends! Here are three fun math activities to get you started:
1. Circle Art: Have students create pictures using only colored circles. It is important that the circles become perfect circles. You can purchase circle cutters in craft stores that carry scrap-booking tools. They are great for cutting out circles quickly without any measuring!
2. Sir Cumference and the First Round Table: Read Sir Cumference and the First Round Table: A Math Adventure. After reading, review the definitions of circumference, diameter and radius.
3. Pi Day Chain: Make a pi chain out of strips of construction paper to reinforce the idea that some numbers never repeat or end. Assign a color to each digit, including zero, and then link the paper circles of those colors into a chain using the digits of pi as a guide. The first strip, representing the first number 3, should be wider than the rest. All the other strips are the same size.
We hope you have a fun time celebrating. And, don’t forget to have a slice of your favorite pie, too!
