What do you notice about the pattern of the beads?

In this activity, you’ll turn a number into a necklace. Pi (π) is the name of the number you get when you divide the circumference (distance around the outside) of a circle by its diameter (distance across it). No matter how big or how small a circle is, the value of pi is always the same!

Pi is an amazing number – it goes on forever! It’s an irrational number, which means it cannot be defined as a fraction. Pi is approximately 3.14159 but it has an infinite number of decimal places. The latest calculations include more than 31 trillion digits!
What’s more, the digits that make up pi don’t seem to follow any pattern at all, but if you count how many times each digit is represented in the first 100 decimal places, you’ll find they all occur around the same number of times – between 8 and 14.
Pi can be used to check the accuracy of a super computer. This is done by asking the computer to calculate millions of digits of pi, then confirming the results against known digits.
