Pi Day Activities for Little Kids

March 4, 2023 by Sarah White Leave a Comment

Pi Day is celebrated on March 14 (because the date is 3.14, the beginning of the number for pi), and it’s a great time for kids of all ages to craft with circles, play with numbers, and maybe even eat some actual pie.

If your kids are younger but you still want to have some fun with this holiday, read on. (Activities for older kids to come!)

To introduce the idea of pi to younger kids, explain that it’s a number that expresses the relationship between a circle’s diameter (the measurement across the center from edge to edge) and its circumference (the measurement of the outside edge, all the way around).

Pi is an infinite number and the same digit never repeats (meaning there are, for example, never two 3s in a row).

Since pi is about circles you can make circle prints, cut our circles, use circles in art projects, eat round snacks. Go on a circle hunt! Play ring around the Rosie, or follow the leader in a circle. So many easy ideas.

Pieces by Polly talks about making fraction plates, repeating patterns with pies, making art with circles and making tiny snack pies.

Tinker Lab has a cute pi day printable art challenge. Can you use three colors to decorate the grids with different patterns in 14 minutes?

Royal Baloo has a fun printable pi board game where you collect cards with the goal of getting as many digits of pi as you can.

Teach Beside Me has a printable pi puzzle that goes together to show 25 digits of pi. It’s not as easy as it sounds because the digits repeat.

And this free pi poster from Cindy Lam at Teachers Pay Teachers can be filled out with one child or a whole classroom and includes fun things like listing your favorite thing that’s a circle or words that have the letters pi in them.

Celebrate Inventor’s Day by Learning about Inventors

Several countries have a day set aside to honor and recognize their inventors, but Nov. 9 is a special one that’s known as Tag der Erfinder in German. It’s celebrated in Germany, Austria and Switzerland and it falls on Nov. 9 because that’s the birthday of Hedy Lamarr.

Hedy Lamarr is widely known as an actress but there’s a lot more to her story. You can get a little of it geared to little kids in the Little People, Big Dreams book Hedy Lamarr (32 pages, hardcover, published 2023 by Frances Lincoln Childrens Books, suggested retail price $15.99).

The book explores her birth in Austria and how she spent time when she was young coming up with inventions. She became an actress, married an arms dealer, made her escape to America and became an actress again.

But she also helped develop a frequency-hopping signal device for airplanes that was used by the Americans and their allies during World War II. That technology became the basis for wireless technology such as wifi and GPS.

While Inventor’s Day is a great time to learn about Hedy Lamarr, you can take this opportunity to check out books and do little studies on lots of different inventors. If there’s an inventor or an invention your child is particularly interested in, that’s a great place to start. It’s fun to think about all the things we use every day that didn’t always exist; someone had to invent them!

For a start here at Craft Gossip you can learn more about Garrett Morgan, who invented traffic lights; Maria Oroso, who developed a clay oven that could cook food without electricity; and more female inventors and scientists.

And for more general inventors’ fun, check out this inventors word search from Fun Findery (and another from Let’s Do Puzzles) or take a quiz on inventors and their inventions from Flanders Family Home Life.
