Each year, March 14th brings the celebration of Pi Day. This year, 3/14/15, is even a little more special. Pi (represented by the greek letter shown to the right) is an irrational number which is equivalent to the ratio of the circumference of a circle to its diameter. This ratio can be simplified to approximately 22/7 or 3.14159... This is why Pi Day is celebrated every March 14th (since 3/14 are the first three digits of pi) and this year is extra special since 3/14/15 are the first five digits of pi.
This post is a week early in order to give you time to prepare for your Pi Day celebrations. Here are some ways you could celebrate Pi Day at home and/or in the classroom:
- bake a pi(e) or decorate some other Pi Day treats
- baking is a great way for children to practice following directions, measuring, and working with fractions

- complete an activity to learn more about pi
- this is an activity I have used (parts of) in my classroom for several years (that accompanies Sir Cumference and the Dragon of Pi, above) - you could also complete part or all of it as an activity at home
- memorize as many digits of Pi as you can
- here are ONE MILLION of them, to get you started!

Age/Grade Guidelines:
In Massachusetts, the Common Core State Standards have been adopted. Pi is introduced in 7th grade when students use pi in formulas to calculate the area and circumference of circles. Students learn about irrational numbers, in general, in 8th grade. (CCSS.MATH.CONTENT.7.G.B.4, CCSS.MATH.CONTENT.8.NS.A.1)
But remember, Pi Day can be celebrated by mathematicians of all ages!
