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!
Over the last four years, we've loved seeing participation grow. In 2022, 1100 schools registered to take part and 14 schools received a £250 grant thanks to the small grants fund we organise with Mayor's Fund for London.
This year, we want to highlight how making maths fun and relevant can enable success in all areas of everyday life. We hope you and your class will join us to celebrate!
