What is Pi – ? ?

The number ? is the ratio of a circle’s circumference to its diameter – it is always the same number, regardless of how big or small the circle is. ? is approximately 3.14159 (rounded).

The last calculations of Pi date back to 2019, when it had been calculated to 31.4 trillion decimal places… but it is consider to be an infinite number.

? – Pi information and further facts

Want to read more about ? itself? Wonderopolis is a great website to get all your basic Pi questions answered from What is Pi? to What is an irrational number? and of course What is the final digit of pi?

Most activities will explore the first set of Pi digits. Here is a good reference for you to get you started. I am sure most projects will not go past a 100 decimal places:

Pi to 10 digits: 3.1415926535
Pi to 100 digits (spaced into sets of 10, so you can take the size you find most useful): 3.1415926535 8979323846 2643383279 50288419716939937510 5820974944 5923078164 0628620899 8628034825 3421170679

Pi Day Paper Chain

A paper chain is a fun way to represent the number Pi using strips of construction paper. Pi Day Paper Chains are easy to set up and make. You can literally just grab some colorful paper and get started, or grab a copy of my handy downloads. A fun an simple activity to get students thinking about the Pi digits and decimals.

Pi Day Bracelets

Pi Day Bracelets

Pink Stripey Socks as a dual approach to the Pi number… you can either assign a colour to individual numbers 0 through to 9 or work with odd and even numbers and colors. Then grab a bunch of beads (any beads, from Perler beads to regular beads) and start threading. Resulting in two pi day bracelets. If you keep threading then these Pi bracelets quickly will become a fun pi necklace!

A poem for Pi day

Write a Pi-Ku Poem

Writing a poem on maths class may not come natural to most Math Teachers.. but it is a fun variation on the topic of Pi and make sore a different kind of lesson. A pi-ku poem is based on Haiku poems – quick, short poems with minimal syllables in each line. For Pi-Ku poem, use each digit of the Pi to determine the syllables of each line:

  • Line 1: 3 syllables
  • Line 2: 1 syllable
  • Line 3: 4 syllables
  • and so on…


I like pi


Quirky, fun but


You catch my drift!

Inspired by the Pi-ku? Well how about a pi-lish poem? Our family code, tells us all about it here. Here is another example of how to Write a Poem in Pi-Lish!
