Free Pi Day Activities: 7 printable worksheets

Like What You See? Tell Your Friends!

PI Day is around the corner, on March 14th. So I wanted to put together some great free printable pi day activities for you to enjoy either at school or at home.

We love to do fun holiday activities throughout the year and try to celebrate as many holidays as we can.

In our Homeschool of 1 though, March 14th means something different! It is my mom’s birthday.

Funnily enough, though we actually had no idea until about a month ago that PI day was even a thing.

As we are from the UK we write the dates like this 14.03.2023. So as you can see not even my math-loving family would have spotted the connection.

Since we now live in America though I was writing her birthday in a diary and spotted it. Wait, what….. my mom’s birthday is 03.14 hmm now that looks more familiar.

As this is an extra special holiday for us I have put together these 7 fun PI Day activities for you to enjoy.

What is so special about 3.14

When I was younger I knew the first 10 digits of PI: 3.14159265359, it was one of those weird things I remembered. Like I knew the phone numbers of my best friends off the top of my head.

My son couldn’t even tell you my number never mind his friends as well. I love this new modern age that we now live in, but I am sure my memory was much better when I had to remember things!

PI Day was officially born in 1988 by exploratorium physicist Larry Shaw. It was turned into a holiday by congress in 2009.

I think I must have been living in a cave for the last 40-something years. It is also Albert Einstein’s birthday.

I am going to be calling my mom later and telling her that not only is her birthday a national holiday she also shares it with Einstein. She always knew she was special!
