## 3.14 – Pi Day Activities |

March 14, better known as Pi Day. Pi is the symbol for the ratio of the circumference of a circle to its diameter. This is a day dedicated to making math fun! Here are some activities and resources for you and your mentee during the week of Pi Day! Tell us about the activites you try.

**Explain Pi**

Pi can be a difficult concept to explain for people of all ages. Here is an activity you can do to visualize what 3.14 means. Find a cylindrical object, wrap a string around the outside of the cylinder and cut the strong so it is exactly the cylinder’s circumference. Take the circumference string and stretch it across the diameter of the cylinder. How many diameters would you be able to cut from the string? The answer should be three and a little piece left over, or 3.14. (Activity from Disney Family Fun, check out the site)

**Paper Chain**

Create a Pi Chain with loops of construction paper – use a different color for each of the ten digits. Try to make the chain 100 links long!

**Read about Pi**

Research what Pi is, who discovered it, the mathematics behing it. You can use the internet or books in the school library. If you have a younger mentee, check out the book “Sir Cumference and the Dragon of Pi: A Math Adventure” by Cindy Neuschwander.
