Pi Day Fun Activities and Printables for Kids

Activities for KidsPi Day begins on 3/14 at 1:59:26 AM.

There’s a large shiny metal sculpture of pi in one of our local parks. My three-year-old daughter asked what it was. I knew it was the mathematical symbol for the number pi, beginning with 3.1415926, but I wasn’t prepared with a helpful answer for a child. That was six years ago.

My daughter and I have collected and explored many fun facts and resources since then. Nowadays, math is my daughter’s favorite subject and she’s looking forward to Pi Day, March 14 (3/14 beginning at 1:59:26 a.m.). For most of us, it might be easier to make a special observance at 1:59 p.m.

We like to start with the free BrainPOP animated video about pi and the What Pi Sounds Like music video.
