Professional Learning for Busy Educators

Hi guzzlers.

Tomorrow is Pi Day – March 14 – the annual excuse for the mathematical community to circulate puns about buns. I mean to honour pi, the ratio of a circle’s circumference to its diameter, which to two decimal places is 3.14, hence 3/14, as the Americans write tomorrow’s date.

In recent years Pi Day has gone from a geeky American eccentricity to a global celebration of maths, and I’m getting my r’s in a day early with two puzzles from the brilliant minds at Brilliant.org. (That’s r for radius, obvs.)
