## Happy Pi Day! 3-14-15 @9:26:53

#### A day late but 100 years early! Did Pi Day sneak up on you? Did it come and go and leave you wishing you would have done something with your students? Well there is always next year or the next millinium. Read how others spent Pi Day and/or tell us what you did to commemorate the day.

**We have only waited 100 years for this day, Pi Day! Why is this Pi Day monumental? This Pi Day makes use of more of the numbers behind Pi**:

**3.141592653**

**So that gives all of us who are involved**

**involved in math in any way, which we all are, to celebrate this day in a monumental way! Truthfully, it almost passed me by. So I thought I would do a little bit of research and see how people celebrated this Major Math Day! http://www.piday.org/million/ Pi is actually 300 years old when William Jones a Welsh mathematician, first wrote the symbol for Pi. Archimedes, many years before, figured the the " Pi is the mathematical constant that represents the ratio of a circle's circumference to its diameter, and its decimal representation famously never ends and never repeats**" (Wikipedia)."

**He did so by using a thousand sided polygon which he had built. (A thousand sided polygon!!! What the heck does that look like? I'm still impressed with his bathtub!) As of late, with the help of computers, Pi has been figured to the trillion digit. As of 2015, Pi Day has been celebrated for the past 27 years.**

**How did people celebrate Pi Day this year? and What can we do next year? Or 100 years from now, if you only go in for the BIG day:**

**Some people made little pies, lots of little pies.**

**Make t-shirts with the Pi and Pi DAY on them.**

**3.14 looked at backwards as in a mirror spells 'pie'**
