It’s Pi Day! March 14th is 3-14 which is the same number at Pi: 3.14. We celebrated with little apple pies and reading some books about Pi!

## What is Pi?

Pi (π), the 16th letter of the Greek alphabet, is used to represent a mathematical constant. Pi is the ratio of the circumference of a circle to its diameter. Pi equals the circumference divided by the diameter (π = c/d). Also, the circumference is equal to pi times the diameter (c = πd). The cool thing is that no matter how large or small a circle is, pi will always work out to be the same number.

To celebrate Pi Day, we are eating yummy apple pies. We made some little mini ones in a muffin pan.

We read two books- one about Pie (How to Make an Apple Pie and See the World) and one about Pi (Sir Cumference and the Dragon of Pi).

I think we will be eating pizza today & measuring it! Are you celebrating Pi Day?

Happy Pi Day! We celebrate Pi Day annually by bringing pie to school and work and eating pizza pie for dinner. We also wear the symbol somewhere on us and take holiday family photos. This year we made a banner full of circle and practiced writing the numbers of Pi. Thanks for sharing your Pi Day fun!
