Pi Day (March 14th) is fast approaching!! With standardized testing all week, I really haven’t been doing much teaching, so I thought it would be fun to share how I plan to celebrate the biggest math holiday of the year with my classes next week…

My Pi Day celebration begins with a little prep work at home:

– I make a couple of pies to bring in for my classes. I usually make Oreo Cool Whip pies as they tend to be a hit with the kids (and only take about 5 minutes to make)! I also allow my students to bring in their own pies so that there is a variety and something for everybody.

– I also make a bunch of chocolate pi symbols in my pi ice cube tray. (Another gift from a former student). I use these as prizes for the games we play in class.

– I tell my students a couple of days ahead of time that I will be holding a pi digit memorization contest on Pi Day so they can study the digits if they plan to participate in the contest. I also do a pi poetry contest where the students who are interested type up a poem about pi ahead of time and bring it in on the big day.

On Pi Day I do different activities with each class…

– I have my 6th graders bring in cylindrical objects on 3/14. I have them “discover” pi by measuring the circumference and diameter of their objects using a string and dividing the circumference by the diameter. We keep track of everyone’s results and come up with a class average which is (usually) pretty close to pi. We eat pie during class and the students who entered the poetry contest read their poems to the class. I then do the memorization contest with them. The student with the most digits memorized gets one of my chocolate pi’s that I made in the ice cube tray.

– My 7th graders have already learned circumference and area so I have them do a page of challenging pie-themed word problems dealing with circumference & area. I give a chocolate pi to the student who correctly completes the 5 word problems first. After the word problems, I play circle bingo with the kids. The bingo game requires them to either find the radius, diameter, circumference, or area of a circle. The winner of the bingo game (you guessed it…) gets a chocolate pi! I then have students share their pi poems and do the memorization contest with my 7th graders. The kids, of course, eat pie during class, as well.

– I like to play Pi Trivia with my 8th graders while they enjoy their pie. I break the kids up into groups of 4 and ask them a bunch of random facts relating to Pi. Each group holds up their answer on a mini whiteboard and I keep track of the score. The members of the winning group each get a chocolate pi symbol. Some of the questions are academically focused while others are humor-based. I conclude class with the poetry reading and memorization contest with them, as I do with my 6th and 7th graders.

– During my lunch, I have some of the other teachers vote on the best pi poems and come up with a winner for each grade level. The winners, of course, go home with chocolate pi symbols!

– I like to celebrate pi minute with whichever class happens to be in my room at 1:59, too. We start cheering loudly (and sometimes some of the nearby classes pick up on it and cheer, too)!

All-in-all it is a very fun, exhausting, and FATTENING day….but well worth it! It’s always a great day!

This bundle contains the Pi discovery activity I do with my 6th graders, the Pi bingo game I play with my 7th graders, and several other circle-themed activities – Circumference, Area, & More: A Circle Bundle.

I would love to hear ideas of how other teachers celebrate 3.14, so please feel free to share in a comment below!

Wishing you all a very happy Pi Day!!
