Pi Day is celebrated each year on March 14th all around the world. It is a day devoted to the Greek letter π, which reprensents a constant : the ratio of the circumference of a circle to its diameter. As Pi (pronounce it like the word "pie") is an irrational and transcendental number, it will repeat infinetely without repetition or pattern.
Today, the pupils of the European Section are welcoming others pupils to present them many games around π ( a πnata, a π hunt, a π quizz....). Let's have fun doing maths :)
