### Celebrate Pi Day in the Math Class

Next week we celebrate National Pi Day! On March 14 (3.1415926...) we recognize the never-ending number π with classroom celebrations, special events, food, song and rhyme

Pi Day is a holiday celebrating the mathematical constant, π. For 2015 the date includes the first 5 digits of Pi—3/14/15. If you hold your celebration at 9:26, you will have covered the first eight numerals: 3.1415926.

This year marks the twenty-seventh annual Pi Day. On March 12, 2009, the U.S. House of Representatives passed a non-binding resolution recognizing March 14, 2009, as National Pi Day.

Pi is the ratio of the circumference of a circle to its diameter. Pi is always the same number, no matter what size circle you use to compute it.

You might want to plan a Pi Day celebration for your students to help them remember this special number. They could write their own songs and poems, see how much of the number Pi they can recall, draw pictures of what comes to mind when they hear the word infinity, solve a Pi-related brainteaser, and enjoy some Pi-related snacks.

You could even hold a school-wide Pi-athalon at 9:26 where you have students ride tricycles, eat pie, recite the digits in pi, solve pi-related brainteasers, etc.
