Pi Day

Updated on June 29, 2013

Pi Day

Pi Day is an international holiday that is celebrated by the entire world on March 14. The reason Pi Day is celebrated on March is that the first 3 numbers form number 3.14 which can easily be changed to 3/14, or March 14. Pi is an irrational number that goes on forever without end. There are more numbers in Pi than there are people on Earth, so remember infinite numbers of Pi can be very hard. However, people like Daniel Tammet have been able to dictate many digits for Pi. In fact, Tammet dictated over 22,000 Pi digits during the 2004 celebration of another Pi Day. Jump into Pi Today, but you will never see the end of Pi as a number and as a holiday!

Pi Is Like A Vortex

If you are wondering how many digits Pi has, you can think of Pi as a vortex without an end. Somewhat like the cliff at superman's icy location (base), there is no bottom/end in Pi. Based on the picture, Pi also looks like a tornado without a bottom. The main idea is that Pi is an irrational number with a beginning, but no end.

Founder of Pi Day

Larry Shaw, a physicist at San Francisco Exploratorium is the founder of Pi Day. To this day, Pi Day is celebrated in the Exploratorium. The House of Representatives announced Pi Day a national holiday back in 2009. In 2015, Pi Day will begin at 9:26:53 to honor more numbers of Pi which can be represented as 3.141592653... There will never be an end to Pi or its holiday!

Activities for Pi Day

Pi Day celebrates 3.14...., an irrational number. There are some fun activities that you can do during Pi Day! For example, you can have 10 different colors of paper and make a key. So, yellow papers=3 and black papers=1. You can line these papers up for as long as you want to get the number of Pi.

Get plates and put a Pi Sign in the middle. Plates are usually shaped like circles, and eating off of a Pi plate wouldn't hurt!

Make a pie, measure the circumference, diameter, radius, volume, etc. Then you can eat that tasty pie!

Compete with your family members to say the most digits in Pi.

There are also so many more ways to celebrate Pi Day!

Pi Day Is Tomorrow!

Pi Day is tomorrow on March 14, 2012 and is an exciting time for all math teachers, students, experts, and people just like you! Pi Day celebrates the irrational number known as Pi that starts off with the first 3 digits, 3.14 which looks like 3/14 on Pi Day! I can't wait for Pi Day, can you?

Happy Pi Day!

Pi Day is among us today on March 14, 2012 (3.14). I can't wait to celebrate by reciting some of the digits of Pi and using pieces of paper to represent the numbers! Today is also Albert Einstein's birthday! Two great events for math put together means a lot of celebration!

Pi Day Is Now Over

But It Will Be Back

That Pi Day was fun. I piled up papers with 10 different colors and got up to 100 digits in Pi. I didn't have pie last year, but I will next year. I love Pi Day and hope that is comes around soon.

Pi Day

Pi Day was created and first celebrated by Larry Shaw. He helped make this wonderful day happen, and this is one of the few math holidays that is celebrated around the world. The universe celebrates Pi because it is part of the Universal Set of Real Numbers. Pi Day is full of activities for teachers, students, and family. Pi Day is an amazing day in which everyone has a fun time.

Circles

Since Pi is used to find the area and circumference, I thought it would be a good idea for me to talk about circles.

  • Circles have infinite lines of symmetry.
  • The diameter of a circle is a straight line (180 degrees) that cuts the circle in half.
  • The radius is half of the diameter.
  • There are infinite diameters and radii (plural of radius) in a circle.
  • Circles always measure 360 degrees.
  • Everyday, we will stumble into something with a circle shape, but we might not remember it all the time.

Notebooks

You might need these notebooks for school, or you can write all of the digits of Pi (all that you can write) into these notebooks. Get started today!

Please Help

I am collecting money for my college fund so I know that I will be able to pay it off when I reach that next step. So, if you have some spare change on you, would you please make a small donation by clicking here
