Celebrate Pi Day!
What Is Pi?
Pi (3.14159265359…) is the ratio of the circumference of a circle to the diameter. If you divide the circumference of any circle by the diameter, you will always get exactly the same number, Pi. Mathematicians use the symbol π to represent pi. That makes the formula for the relationship of the circumference of a circle to the diameter π= c/d.
While Pi is a constant, it is also irrational, meaning the number goes on forever, or infinite. You can see the first million digits at PiDay.org, but you can never see the last number.
Learning About Pi
Anytime we assign a number or concept a symbol, it can seem complex and hard to understand. This isn’t true with pi. We can demonstrate pi with the following Pi Day activities that will make π easy to understand.
This History off Pi video gives more information about the history and how the calculation of π has developed over the centuries. It is geared for your middle and high school students.
