Let Them Have Pi!

Posted by EiE Team on Thursday, March 11, 2021

This week, we’re celebrating Pi Day! This international day of celebration is in honor of all things math - but especially focused on the amazing impact of Pi!

Pi, often expressed π, represents the ratio of a circle’s circumference to its diameter. This ratio is always the same, numerically represented by a fraction that we haven’t yet found the end of, despite being referenced as far back as the 17th century. So far, we know over 38 TRILLION digit places of Pi and we’re still no closer to the end. However, when using it for calculations we round the fraction to 3.14 and, thus, celebrate it on March 14th. 

The incredible versatility of Pi has led to advancements in math and science, computer technology and engineering. And, with the latest technological innovations, we’re understanding the power of Pi more and more. You can learn more about the history and practical applications of Pi by clicking here. This Pi Day, celebrate with your learners with 3.14-themed activities and pie-related puns. Try a scavenger hunt to search for a sweet prize or see how long you can build a paper chain with Pi digits written on each coil. Enjoy stories like Sir Cumference and the Dragon of Pi or Donald Duck in Mathmagic Land. However you celebrate, enjoy this day to reflect on our ever-expanding knowledge and the importance of math!

For more information on the connection between Pi and Computer Science basics, as well as information for math and CS educators in celebration of Pi Day, visit The Raspberry Pi Foundation and check out our fully integrated Computer Science Essentials Program. Plus, visit PiDay.org for teacher resources, math help and more. 

The Museum of Science, Boston, is running a fundraising campaign to coincide with this special date. Your Pi Day gift —even $3.14—combined with others makes a difference. We appreciate your help supporting our STEM (Science, Technology, Engineering, and Math) exhibits and programs that engage and inspire learners of all ages.
