International Day of Mathematics

IDM logo
The International Day of Mathematics is a project by the International Mathematical Union (IMU) and was proclaimed by UNESCO.

How are you celebrating the International Day of MathematicsOpens a new window (IDM) 2022? This year the theme is Mathematics Unites, and we’ll be looking at how we can study how united we are across the world.


The video below is a short presentation during which we look at how closely connected we all are and set an investigation for your students to try.

This activity is suitable for all 11-16 students. It doesn’t rely on understanding of maths beyond Key Stage 2, however the application of the maths will be new to most, if not all.


We’re also running a competition based on the investigation, with prizes for winning entries. It’s designed to be run in one lesson, however your students may choose to take some extra time on their work (and this is to be encouraged).

To take part, your students will need to produce a poster showing their investigation. Without giving too much away, they may want to use technology to help with the investigation and we’ll accept entries in the form of Desmos or GeoGebra files if your students prefer to work in this way – some students may even want to use some Python or similar. However, hand-written maths is always welcome. We’ll be judging students’ posters based on the mathematical content, as well as the artistic flair shown!

All entries should be emailed to [email protected].
