[Surnetkids] Pi Day

Dear Reader,

March is here, and here’s a quick look at what’s coming up this month.

March is Women’s History Month and National Nutrition Month. March 6, 1836 was the fall of the Alamo, and March 10 is Harriet Tubman Day. And, of course, March 14 is Pi Day! For more, visit Surfnetkids March Calendar.

See ya on the Net,

Pi is the ratio of the circumference of a circle to its diameter. Regardless of the size of the circle, pi is always the same irrational number: approximately 3.14. Thirty years ago, physicist Larry Shaw created a Pi Day celebration on March 14 at the Exploratorium Museum (see first site review) and it has grown into an international day of wacky mathematical celebrations at schools and universities around the world. Additionally, July 22 (22/7 in European date format) is often celebrated as Pi Approximation Day.

Exploratorium: Pi Day

If you can’t make it to San Francisco’s Exploratorium for Pi Day, you’ll find lots here to inspire your own celebration. Highlights include a Short History of Pi, Pi Limericks, Pi Haiku (called Pi-Ku), printable Pi Posters, and two pi activities. Discovering Pi is a hands-on activity measuring circles and recording their circumference and diameter. Cutting Pi is an exercise exploring the relation between circumference and hat sizes.

Math is Fun: Pi

To find pi yourself, measure around something circular like a plate, then measure across the circle. The first measurement is the circumference, and the second is the diameter. Now, divide the circumference by the diameter. Depending on how accurately you measured, you will get a number very close to 3.14. Visit Math is Fun for more pi exercises, a pi quiz, and an easy way to remembering the first six numbers of pi: 3.14159.

NASA: Take the Pi in the Sky Challenge

“You may already know all about the mathematical constant pi (π) and how it can be used to calculate things like the circumference of a circle or the volume of a sphere. But did you know pi is also used all the time by NASA scientists and engineers to explore other planets? In this challenge, you can solve some of the same problems NASA scientists and engineers do using pi!” In addition to the challenge slideshow, there are also downloadable posters to decorate your classroom or bedroom.

Quote of the Week

“To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature … If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in.” ~~ Richard Feynman (May 11, 1918 – February 15, 1988) American physicist.
