Pi Day scenarios and ideas

How to celebrate Pi day
some ideas tested
during the project
Mathematics teachers of the "Life is math around us" project are excited to make math fun by celebrating Pi Day.  They love finding new ways to celebrate
and explore various math concepts on each Pi Day: March 14. This is a great opportunity to introduce the number Pi - how it’s derived and how it relates to measurement and circles or show mathematical formulas that use the value of Pi.
It’s also a fun
day to learn about Albert Einstein, because it’s his birthday!  For the project “Life is math around us” math
teachers want to share a fun collection of  Pi Day celebration ideas, that will help kids
develop critical and logical thinking skills.
official Pi day website could be a helpful inspiratory source:
1st idea:
 Learning About
Pi: Unit on Circumference and Area of
Circles. The
Exploratorium's Pi Day Celebration.
The Joy of: - a
theoretical introduction to the number Pi and its universality.
a.     Cutting Pi (Students work in groups. Carefully wrap the string around the circumference of
your circular object. Cut the string at exactly one circumference of your object. Take your “string circumference” and stretch it across the diameter of your circular object. Then cut as many “string diameters” from your circle circumference as you can. Of course, you will cut only 3 and have a small piece
left. Conclusion: No matter what circle you use, you’ll be able to cut three complete diameters and have a small piece of string left over.)
b.     Eating Pi Day Cake.
Evaluation. Congratulations! You learned about the meaning and history of Pi. 
2nd idea:
Student is obliged to bring a bottle of juice, a round cake, plates, a fork and a glass. With the help of the teacher, each student measures the circumference and diameter of their cake. Dividing the circumference by the diameter gives the same number, even though the students' cakes are all different. Also, the same happens with round juice bottles. Here is the discovery - we discovered the number of Pi, which does not depend on the circumference and diameter.
