# Pi Day Activities: 14+ Ways for Kids to Celebrate Pi!

Check out these great STEAM Pi Day activities for kids that pair math with technology, art, engineering, and science!

March 14th is Pi Day! In honor of this international celebration of Pi, we’ve pulled together 14 great Pi Day activities perfect to celebrate with kids of all ages! Pi, or π, is the ratio of the circumference of a circle to the diameter.

In case you need a refresher, the circumference of a circle is the distance all the way around and the diameter of a circle is the distance across the middle.

Pi begins 3.1415 and mathematicians have spent thousands of years studying this irrational number. Trillions of digits of Pi have been identified so far!

Did you know that the symbol for Pi was first introduced by William Jones, a Welsh mathematician, in 1706. The mathematician Euler made the symbol popular, but the symbol of Pi has been in use for more than 250 years! Wow!

According to NASA’s Jet Propulsion Laboratory, you only need about 39 or 40 decimal places of Pi to calculate the circumference of the visible universe with an accuracy equal to the diameter of a hydrogen atom. This is because the visible universe has a radius of about 46 billion light years.

The calculation of Pi is used as a stress test for a computer. The calculation works like a digital cardiogram that indicates the level of activity within the computer’s processor.

The Greek letter for Pi is the first letter of the words periphery and perimeter. Pi refers to the ratio of a circle’s “periphery”, a.k.a. circumference, to its diameter.
