Pi Day

4 Fun Ways to Celebrate Pi Day (3.14) With Kids

Pi Day activities

March 14th (3/14) is Pi Day, the day that celebrates the infinite number starting with 3.14.

Kids first learn about pi when measuring circles, but pi is also used to talk to satellites, to measure how fast and powerful a computer is, and even to study the structure of an eye.

Pi is used every day to make calculations in physics, engineering, modern construction, space exploration and so much more.

Our friends at Mathnasium, a math-only learning center, sent us these fun activities to celebrate!

Activity #1

Search for circular objects around the house. Grab some string or ribbon and scissors.

Wrap the string around the circular object and cut it where it meets. This is called the circumference.

Now place a piece of string across the top of the object, right through the center, and cut that. This is called the diameter

Now for the real fun! Place the diameter string next to the circumference string. Find out how many diameters fit into the circumference. Guess what? It will be 3 times plus a little bit more.

You found pi!

Activity #2

Read Sir Cumference and the Dragon of Pi. This math adventure is centered around a potion that changes Sir Cumference into a fire-breathing dragon. Can Radius change him back?

Join Radius on his quest through the castle to solve a riddle that will reveal the cure. It lies in discovering the magic number that is the same for all circles.
