Pi (π) Day!
In America, yesterday was 3.14 (14th March) so at 1.59 we had 3.14159, the first six digits of pi!
Pi (or π), put simply, is the ratio between the circumference of a circle (its width from one side to another) and its diameter (the total length of the circle), and a concept that has fascinated mathematicians for centuries. For example, a circle that is a circumference of 10 centimetres, unsurprisingly, will have a diameter of 31.4159 centimetres.
To celebrate pi day all our hot food was circular, from pizza to pie, to the delight of many children, who called it "the best lunch ever". If only all learning was so tasty!
