Pi Day Coloring Sheets

Pi Day is better with crayons. Here are free coloring ideas and activity pages you can print at home or in the classroom — no account required.

1. Color-by-digit pi spiral

Assign a color to each digit 0–9. Then print out the first 100 digits of pi and let kids color each cell in a 10×10 grid according to its digit. The result is a one-of-a-kind abstract piece every kid will want to keep.

You'll need: a 10×10 grid printout, ten colors, and our first 100 digits of pi.

2. Giant π symbol

A big outlined π symbol with decorative patterns inside each section — circles, swirls, polygons, math icons. Hand out to early finishers or as a desk decoration project.

3. Pi Day pie

A circular pie divided into slices labeled with pi facts, each waiting to be colored in. Combine with a classroom pie-eating contest for full dopamine points.

4. Pi digit search

Print a block of the first 1,000 digits of pi and ask kids to find their birthday, their phone number, or any sequence they like. Highlight with colored pencils. It works because every short sequence almost certainly appears somewhere in the first million digits.

5. Connect-the-digits pi mural

A large poster version of the color-by-digit spiral for the entire class to work on together. Use the million digits page to pick your starting position.

How to make your own printable

  1. Open the digits of pi page and copy the first 100 or 200 digits.
  2. Paste them into a spreadsheet (Google Sheets works) in a 10×10 or 10×20 grid.
  3. Set row height and column width to create squares.
  4. Print with "no gridlines" turned off so the borders show.
  5. Hand out alongside a legend mapping each digit (0–9) to a color.

Why coloring pi works

Turning abstract numbers into visual patterns is a well-known trick for making math memorable. When you color every "3" blue and every "7" orange, something remarkable happens: the randomness of pi becomes visually beautiful, and the repetition helps kids internalize the sequence. Many Pi Day champions say their first 50 digits came from an art project like this.
