Next Tuesday is Pi Day - 3/14 in the American date format.
Within their maths lessons, pupils in Year 7, 8 & 9 will take part in Pi Day activities including a Kahoot and dingbats.  There will also be the chance to win a £10 Amazon gift card for the pupil who can recite the digits of Pi to the most decimal places - and there are literally gazillions of them!
To help with the memorisation of Pi, pupils are encouraged to use this song to help.  Check it out here>> 

Or if you want more than 100 places, this website has one million digits of Pi >>  www.piday.org/million

How will you get on?

What is Pi?

The ratio of a circle’s circumference to its diameter is always the same: 3.14159… and on and on forever. 

Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That's because Pi is what mathematicians call an 'infinite decimal' — after the decimal point, the digits go on forever and ever so we’ll never figure out its exact value no matter how close we seem to get. 

The record for memorising digits of π, certified by Guinness World Records, is 70,000 digits, recited in India by Rajveer Meena in 9 hours and 27 minutes on 21 March 2015. In 2006, Akira Haraguchi, a retired Japanese engineer, claimed to have recited 100,000 decimal places, but the claim was not verified.

The first 100 digits of Pi are:

3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 58209 74944 59230 78164 06286 20899 86280 34825 34211 7067
