Let’s start with baking a Pi Pie!

Resources:

Ingredients for a Pie

Cost: Medium

Difficulty: Medium

Any circular pie with any flavor will do but have some extra pastry to get your pi Symbol on top. It will be a great addition to any fundraising event!

Create a fantastic and Easy Pi Day Paper Chain

Resources Required: 

Plenty of paper with 10 separate and vibrant colors. 

Scissors or guillotine

Glue

Bright and colorful pens.

Cost: Low (normal classroom resources only)

Difficulty: Medium

Similar to our favorite irrational number pi, paper chains can go on and on and on forever! With a whole class or an entire year group, you can create a simple but impressive Pi Day paper chain with endless loops of construction paper. What we can do is use different colors for every one of the 10 digits (1, 2, 3, 4, 5, 6, 7, 8, 9, 0). Each piece of colored paper in the chain will represent a digit (or decimal place) in Pi. With teachers around the world getting into Pi Day to celebrate mathematics and have even attempted to beat the world records. So how long can you get your Pi day paper chain? How long could it be if you can get the whole school involved? Why not go for the world record in paper chains!

Create a human Pi chain

Resources Required:

Pi printed on separate paper

1183 or more people!

Cost: Low to Medium depending on arrangements and organization costs

Difficulty: HIGH

Can you just imagine having an entire class getting lined up so the numbers they are holding creates the value of Pi? Well, what about the entire school? That is what The Sultan’s School (Oman), in Seeb, Oman, did on 14 March 2018 to celebrate pi day. They had a whopping 1,182 participants to secure their place in the Guinness book of world records. Why not get your entire school involved? What about your other local schools? Maybe with a little planning, you can beat that record and some!

Memorizing the digits of Pi

Resources Required:

Printed or electronic list of digits of Pi to 100 decimal places or more!

Some Pie as a super and delicious prize!

Cost: Low (printing costs + a prize)

Difficulty: Easy

This is an easy and fantastic way to get the kids involved with pi day! All you need to do is hold a contest to see who can recite the most decimal places of pi! They can start up to 100 decimal places but this activity can be extended easily by giving them even more decimal places! Not to mention, once they know pi to 100 decimal places it makes a good party trick! Why not make it interesting with a delicious prize of apple pie?

To help you get started on the memorization of pi, why not watch a catchy song about the first 100 digits of pi! You can find it on Youtube. You can even play it in the background while your students get to work on one of the other activities and projects!

Pi Word Competition

Resources:

Some know-how and a timer

Cost: Free

Difficulty: Medium

Of course, we say Pi so we think Pie and that’s why we want a Pie eating contest! But a Pi-writing contest is even better. Give the kids three minutes for them to write as many words they can that start with the two little letters Pi!

Let’s get into the Maths of it all!

Resources Required:

String

Rulers

Various circular objects to measure.

Cost: Low

Difficulty: Medium

We can’t truly celebrate Pi Day without getting our hands on our notebooks and doing some of the maths! As it is a favorite with maths teachers in the UK to get students discovering pi, grab some circular objects such as tea caddies, soup cans, tins of baked beans, pie tins, clocks, paper plates, bowls, candles, old CDs/DVDs and so much more. To make it easier on ourselves, why not set the homework to bring in 3 circular objects to measure! 

You can then get the kids to measure the diameter (this is the distance from each side of the circle but must go through the center of the circle) and the circumference (the length that goes around the outer edge of the circle). All we have to do now is to divide the circumference by the diameter and sit back as they discover the amazing ratio we know and love as pi. 3.14 every single time with every circle!

Why not make it interesting and run a competition for the most accurate measurements. The more accurate decimal places of pi they get the bigger the reward! Or even better why not bring some treats to measure then eat! With cookies, donuts, and of course pies available for a mathematical munchie afternoon!

There’s no party like a pizza Pi party!

Resources

Pizza!

Pizza cutter (why not get a Pi shaped pizza cutter)

Cost: High

Difficulty: Low

Pi Day isn’t Pi Day without a PIE! So why not make it a Pizza Pie! After all, they are circular and are used by mathematicians around the world to help explain circle properties. From describing the radius as the length of your slice to manipulating the pizza slices to demonstrate that the more sections of pizza there are the closer we get to a true parallelogram!  Thus, explaining the area of a circle. Pizza is also good for fractions in maths so a way to include the younger ones and learn about fractions on pi day! After all, for century’s Pi was approximated to a fraction 22/7! Why not take the Pi day lesson further and discuss the ratios between one smaller piece to the larger piece, a great way to compare the ratio of lengths and areas!  So let’s get cutting our favorite pizzas! Pepperoni with extra cheese, anyone?

Some paper Pi Plates please!

Resources:

Paper plates

Colour Pens

Construction paper

Glue Sticks

As our little ones at home are likely not to be ready to comprehend pi and what it represents, this activity is a great substitute! We can get stuck into our pies on pi days with some simple maths activities that introduce them to circles, ratios and fractions! Cut up your paper plates to represent a few different fractions and kids can then mix and match the pieces to make a complete “pie” to decorate and even label. This helps the kids learn about circles, you can add fractions into the task by having, for example, ½,¼,⅛ and 2 1/16 pieces that they can put together.

Become a Conductor and produce an epic pi symphony!

Resources

Some musical instruments

Cost: free

Difficulty: easy to medium depending if you use your own instruments.

Yes, that is right Pi can be music! An experimental adobe flash player based application called pi10k, this is a very simple and easy to use app but we find it easier to run on Microsoft Edge rather than google chrome as you need to authorize the use of flash on many computers depending on your settings. It is so simple to do as you simply select 10 notes of your choice on the keyboard. Each note represents the digits 0-9 and then will be played based on pi. So the third note, then the first and then the forth and so on and so forth. It plays a very unique sympathy! And great fun for pi day!

Why not push the musical whim and use different sounds for each number such as a clap for 1 whistle for 2 and so on! So get the triangles, drum kits and recorders ready! The first 20 to 30 digits of pi should be enough and then repeat it over and over to get a good rhythm to demonstrate.

Put together a fantastic puzzling pi puzzle

Resources:

Puzzle from Standards Puzzle

Cost: High

Difficulty: Low

A company called Standards in Puzzles has created a great series of puzzling puzzles for us to get going on! The series is designed to teach some common core concepts and this particular one is focused on Pi! The puzzle even includes a lesson plan with detailed ideas of how to use this resource to set up 5 stations of activity that the students can move around to. It’s an activity bundle all about Pi day giving you the activities all in one box! You can find Standards puzzles pi creation in Amazon!

Get out your pack of cards and start playing!

Resources: 

Packs of cards

Printouts of pi to 100 decimal places

For a simple card game that introduces our young ones to the concept of cards as well as pi why not play this fun Pi game. It is simple to set up and get the kids into a race to see who can get rid of every single card in their deck. The kids will, therefore, lay out each card in the order of each decimal place of Pi!

Let’s say 3 of hearts then the ace of spades then the 4 of diamonds and so on. 

To help why not print the digits of Pi out on paper, to begin with, so they can have a reference as they go! But don’t forget to challenge the older players to recall as many digits as they can first! Getting it all from memory is so much more fun!

Beads and string to make the bracelets

List of pi numbers.

Cost: Medium

Difficulty: Easy

An easy activity for the young ladies would be making a bead bracelet. They can do this two ways, one way is to have 3 beads of one color followed by 1 bead of another, 4 of another and so on. Alternatively, assign the digits 0-9 with a color e.g. 1 is green, 2 is blue, 3 is red, 4 is orange and so on. Thus the bracelet will go red bead, green bead and then orange bead! 

Have a Photoshoot
