To celebrate 14th March (π day), MathsCity in Leeds is hosting a competition to celebrate everyone’s favourite geometrical shape whose circumference is π times its diameter: the circle.

Visitors to the MathsCity maths discovery centre between Saturday 5th March and Sunday 13th March 2022 will be able to take part in the competition by drawing their best circle on a giant whiteboard. The person to most closely approximate a perfect circle will win £20 to spend in the gift shop!

If you want to hone your skills before you take part, MathsCity recommends this online game you can use to practice. They’ll also be running π-related craft activities through the week (from 8th March).

To visit, you can book tickets on the MathsCity website (£6.50 adult, £4.50 child 3-16/concession, £18 family ticket) and while you’re there you can check out all their other excellent hands-on maths exhibits, games and puzzles, as described by Peter in his review.
