Maths lovers around the world , including those at Rokeby School, have united to celebrate pi day.
It is marked each year on March 14 – or 3/14 to those using the American date system – as the approximate value of the symbol, the ratio of the circumference of a circle to its diameter, is 3.14.
Maths teachers at the school in Barking Road, Canning Town, wore special pi ties and enjoyed pies and custard in the staff room during break.
Students spent the day learning about pi before trying to explain its history and concept in three minutes and 14 seconds.
They were also challenged to memorise pi to as many decimal places as possible, with Year 9 student James Baah able to recall 33 digits.
He said: “I think that pi day was interesting and I remembered 33 digits of pi because when I am revising maths I use my maths dictionary to memorise the digits of pi every week’’.
