International Day of Mathematics

The International Day of Mathematics takes place annually on 14 March. These activities are designed around the IDM's theme of “Maths for a Better World”. With Easter following shortly after the event, the activities for this year are themed around sustainable chocolate consumption. The resources look at particular parts of the chocolate industry and have different tasks for you to choose from.

How to use the activities

The resources have been designed with flexibility, so you can use all or part of the activities to meet your needs. You might like to use them with your class in one lesson, as an extended homework or with an enrichment class.
