March 14 (3.14) is Pi Day!

My middle son's fascination with pi started in third grade.

A quick springtime conversation at recess with one of his friends, and my son conceived his first own personal goal: to memorize the first 25 post-decimal digits of pi by the end of the school year.

I'm really not sure how the topic was introduced at recess; however, when my son burst through our front door filled with enthusiasm for a concept he really didn't even understand at that time, I could deny it no longer. My son was a math nerd. By June 2010, Phillip achieved his goal.

Two years later, Phillip is still a math nerd, and I am very proud of him!

Quick Facts about Pi:

- Pi is the ratio of the circumference of a circle to its diameter.

- Pi is always the same number, no matter which circle you use.

- Pi is an infinite number with no end and no repeating pattern.

- Pi begins 3.1415926535897932384626433... (And, yes, I just listed pi with the first 25 post-decimal digits!)

In honor of my son and all the mathematicians, math teachers, and all around lovers of math in our lives, let's celebrate!

3 Ways to Celebrate Pi Day:

1. Set a Festive Pi Day Mood! Cut out circles in various sizes and colors with your child and decorate your house. Make a construction paper chain: pick nine colors of construction paper and cut into strips, designate a different color for each single digit 1-9, link the numbers to form a pi number chain using the digits on the joy of pi website, stop your chain when you either exhaust your paper supply or your attention span. Hang the paper chain for all to admire. Consider saving your celebratory paper pi chain and adding to it each year!

2. Sing some Pi Day songs by Carolyn Morehouse. Go to the library and read the book Sir Circumference and the Dragon of Pi by Cindy Neuschwander.

3. Serve only circular or pie-shaped foods throughout the day: quiches, donuts, bagels, Cheerios, pancakes for breakfast, pizza pie for lunch, Shephard's pie baked in a circular pie dish for dinner with baked fruit pies for dessert. Include plenty of blueberries, oranges and melon balls for daytime snacks!
