Pi Day (3/14) is the unofficial holiday dedicated to pi. Pi is the ratio of a circle’s circumference to its diameter, and it’s an irrational number, so it can’t be expressed as a simple fraction of two integers. The number starts out with 3.14, but it goes on for infinity!

This special day is also the perfect time to plan STEM-themed activities for your classroom or with your children at home.

Here are five excellent ways to celebrate Pi:

          1. Head to your local or school library and check out a book about Pi! These three titles are a good place to start.
          2. Demonstrate Pi in the real world. San Francisco’s Exploratorium has an entire webpage devoted to simple and easy hands-on activities that introduce the concept of Pi using everyday objects.
          3. Make Pi plates. Have students trace the Pi symbol on a piece of construction paper and then cut it out a glue it to a paper plate. Decorate the border of the plate with Pi’s digits.
          4. Write a Pi-ku, a math version of the traditional 5-7-5 syllabic haiku. A Pi-ku of course, follows a 3-1-4 syllabic pattern.

For example:
Math is fun
When
Mixed with some pie

 5. And, of course, you could always bake a Pi-themed pie!
