PI DAY returned to Parkside School in Cullingworth to excite maths students.
Students in various years took part in fun activities based around the mathematical symbol and its meanings.
Emma Brooksbank, the assistant head of maths, said: “In year seven some students looked at where Pi came from, investigating the relationship between the circumference and the diameter.
“In year 10 Mrs Laoufir made Pi mobiles, involving research into Pi. Year nine looked at different parts of circles, and my class they had a battle with Mr Radcliffe's Year 12 Spanish group, looking at visual puzzles.
“We also had a successful bake sale where students made Pi cakes and buns. It was another very successful Pi Day in the maths department."
The number Pi (π) is a mathematical constant.
Originally defined as the ratio of a circle's circumference to its diameter, Pi now has various equivalent definitions and appears in many formulas in all areas of mathematics and physics.
