What is Maths Week London?
In 2019, we founded Maths Week London to celebrate maths and nurture a love for subject that impacts all of our lives, every day!
This year, our theme is 'The Problem-Solving Playground'. We want to highlight creative and hands-on ways to tackle problems, explore different approaches to problem-solving, and see how maths is all around us – from the classroom to the real world.
Perfect for curious minds, we hope this year’s theme will inspire confidence, critical thinking, and a fresh enthusiasm for maths across the capital to help prepare young learners with crucial lifelong skills.
