National Pi Day Handout

Pi is a constant, infinite number that continues without an end (numbers like this are called “irrational numbers”). Pi is usually represented with this symbol: \pi and is a helpful number for calculating things such as the area and circumference of a circle. Currently, we know 31 trillion digits of pi!

We celebrate Pi Day on March 14th because 3.14 are the first three digits of pi. Print out the handout below to make your own Pi Day bracelet with pony beads and string!
