**If one day of the year screams “Party!” in Math class, that day is March 14. **

**Each year on 3/14, teachers across the globe take a break from the normal routine to plan a special celebration in honour 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!

Pi Day activities are meant to enrich and deepen student’s 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.**

**Pi is a mathematical constant that is the ratio of a circle’s circumference to its diameter, and it is also one of the most revered mathematical constants in the known world.**

Pi Day was first officially celebrated on a large scale in **1988 at the San Francisco Exploratorium**. Since then, Pi Day has been celebrated by millions of students and math-lovers each year.

Dear Report Bee

Thank you for sharing this wonderful piece of information with us. Though I am not a Math teacher and have feared the subject all my life, I thoroughly enjoyed reading the write up on Pi.

I look forward to more of such ‘interactions’ with Report Bee.

Thank you again.
