Pi Day Activities for Kids: Fun Ideas for Infants, Toddlers, and Preschoolers

Pi Day: March 14

March 14 (3.14) is an opportunity to explore circles, shapes, and early math concepts with your child. While infants, toddlers, and preschoolers aren’t ready for the mathematical meaning of π, they are naturally curious about the world, and circles are everywhere!

Here are some at-home activities to celebrate Pi Day.

Pi Day Activities for Infants

Exploring Round Things

  • Rolling Ball Play – Offer balls of different sizes and textures to push, roll, and observe movement.
  • Round Object Treasure Baskets – Include items like jar lids, soft rings, stacking toy circles, and textured teething rings.
  • Bubble Play – Blow bubbles and talk about “round!”, “circle!”, and “pop!”

Circles in Motion

  • Circle Stomp Path – Tape paper circles on the floor for your child to hop, stomp, and dance on.
  • Spin Art Circles – Use salad spinners to make circular art with paint and coffee filters.
  • Circle Hunt – Walk around the room and find circular objects: clocks, lids, buttons, wheels, etc.
  • Rolling Ramps – Let your toddler roll balls or round objects down tubes and ramps.
  • Explore Dots – Use daubers to make dot marks on paper. Talk about how the shape looks like a circle!

Discovering Shapes and Patterns

  • “I Spy” Circles – Look around for things that are circle in shape. Make a list of all that you find! For older children, introduce words like cylinder and sphere to describe the shapes even further.
  • Circle Printing Art – Gather many different circular items like bottle tops, marker lids, a cut-up tree branch, straws, corks, tin cans, pom-poms, and cylinder blocks. Dip in paint and use like a stamp!
  • Make Play Dough Circles – Roll dough into “snakes” to create different sized  circles.
  • Cut Out Circles – Draw or trace circles on paper and invite your child to cut them out. Use the cut circles for art and create a circle collage!
