Pi day

I neglected to inform you all that my first day at Greenwood was Pi day, a day in honour of mathematics' most celebrated number; a day involving maths games and umpteen varieties of pies for shared consumption. I'd never heard of this concept, but all of the American schools seem to observe the occasion. Why March 14? Well, Americans write their date with the month followed by the day, so instead of being 14.3.2007, it's 3.14.2007. And if we leave out the year, we're left with 3.14, which of course is Pi, correct to two decimal places!
