BRIGHT students have celebrated the mathematical constant pi with an unusual challenge.

Pi is the mathematical term used for the ratio of a circumference of a circle to its diameter 3.14 to two decimal places.

It is a number that no one knows where it ends but students at Manningtree High School made a pretty good guess at finding out.

After learning about the history of Pi in their maths lessons, some of the youngsters entered a competition to write down as many digits of Pi as possible from memory in just one minute.

Freddie Eves, from year 9, who has an impressive memory, was crowned winner after successfully writing down a hundred digits.

The students at Manningtree High School pride themselves on their outstanding maths skills and back in February they took part in the Intermediate Maths Challenge.

The national competition is based around problem solving and encourages mathematical reasoning and precision of thought.

Laura Harvey, who is the head of mathematics at the school, said: "We have had our results in, and students did extremely well.

"There were three gold, ten silver and 38 bronze awards.

"Students showed they were resilient and could still get excellent results despite the challenges they have faced over the past few years."
