# Pi Day: Ideas for celebrating 3.14

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!!
