Pi: the Definition Classroom Math Poster

A perfect classroom poster for Pi Day, and every day. Everyone knows about the iconic number Pi, but how many can say exactly what it is? Where it comes from? In this poster the infinite numerical and precise geometrical nature of Pi are plain for all to see, in bright colors and telling figures that students can immediately understand.

True story: In 1897 the legislature of the State of Indiana tried to pass a bill that would have defined Pi as 3.2. Fortunately there was a mathematician in the gallery that day, and he prevented the bill from becoming law. You can ensure that this kind of thing never happens again, by displaying this beautiful poster where everyone can see it!
