Plan a Pi Day Party for March 14

Teachers in many classrooms celebrate Pi Day this month. Pi -- the number 3.14… gets its own special day on 3/14, or March 14. EdWorld editors have gathered a collection of links to ideas and activities that will help you plan a Pi Day celebration for your classroom or school.

If one day of the year screams "Party!" in math class, that day is March 14. Each year on 3/14, teachers in classrooms across the globe take a break from the normal routine to plan a special celebration in honor of pi, or the number 3.14.

March 14 also happens to be the birth date of Albert Einstein -- which makes the day an extra special one for planning math challenges and math fun!

According to Dr. Math, Pi Day activities are meant to enrich and deepen students' understanding of the concept of pi. Activities might include investigations of the value of pi, special pi projects, and parties with pizza or other kinds of "pi."

Because pi is 3.14159…, some schools hold their big Pi Day celebrations 3/14 at exactly 1:59 p.m.

Education World editors took some time to surf the Internet in search of ideas around which teachers might build Pi Day celebrations. The resources below offer a library of great activities, lesson plans, and other resources to help you celebrate Pi Day in style!

Lesson Plans and Other Activities for Pi Day

We have gathered more than two dozen links to Pi Day activity ideas. (Appropriate grade levels for each lesson resource appear in parentheses.)


Make a Pi Chain

Use 10 different colors of construction paper. Choose a different color to represent each digit, 0 to 9. For example: 1=red, 2=blue, 3=green, 4=yellow… In that way, 3.141 would have rings of green, then red, then yellow, then red. Continue creating the chain for 3.14159…
