I love Pi day! This post will give you a taste(see what I did there?) of different Pi Day Activites you can try out in your own classroom!
Activities:
 Circle Shuffle Board
 Pi in the sky/ Piline
 Pi in Pictures
 Memorizing the digits of Pi competition
 Who can get the closest to Pi
 Pi Day Poster
 EATING Pi(e)

Circle Shuffle Board
Materials Needed: Painters tape, Mater sticks, small flat round object
How to play: 1.) Make three concentric circles on the ground. 2.) Tee up the small object. 3.) With the meter stick try to get the object in the smallest circle.

Pi in the Sky/ Pi Line
Materials Needed: Graph Paper, digits of Pi, markers/crayons/color pencils
How to: 1.) Using the digits of Pi color the number of blocks for each digit. 2.) Color the scene creatively like a city skyline.

Pi in Pictures
Materials: 8.5 by 11 paper, markers/sharpies, digits of Pi
How to: 1.)Write each digit 09 about 2 or 3 times on separate sheets. 2.) Line up students in groups of 5. 3.)Hand digits out in order. 4.) Cross of digit after use. 5.)Repeat with next 5 digits.
Imagine doing this every year of your teaching career. Cover their faces with the numbers if you work in Public school.

Memorizing the digits of Pi
Materials: None
How to: Send them home to do this. Have them write it or recite it.
My friend Rory from @ITEACHALGEBRA thinks this activity is pointless. Went on a whole rant about how it is educationally useless haha. I think its fun to do but totally agree about the value.

Who can get the closest to pi
Materials: Various round objects
How to: 1.) Have students select various round objects around the room. 2.) Have them measure the circumference. 3.) Have them measure the diameter. 4.) Each group must divide C/d. 5.) Whichever group gets the closest to 3.14 or 22/7 wins!

Pi(e) Day Poster
Materials: Whatever the kids want to use
How to: Before Pi Day give the students a HW assignment to make a Pi(e) day poster. Tell them that as a class we will vote and the best will win. Great way to get the festivities going!

Eating Pie
Materials: Pies and other random round food.
How to: Distribute and eat!
Traditionally this day was designated for extra credit. Every competition or activity is a way to gain 5 points and because Pi Day usually fell towards the end of the third quarter it was super convenient. I also did most of my Pi day extravaganzas when I was at a private school where testing wasn’t a constraint on curriculum and time. Enjoy!
Also, excuse my lowquality photography most of these are facebook memories from a former time.
