Festival of Triangles

Maths on Toast

Festival of Triangles is a whole-school celebration of maths.

In essence, it's a triangle-themed maths week that leads up to an event, usually held on a Thursday straight after school, to which you invite your whole school community.

During the week, children carry out activities that build up excitement as well as supporting their maths learning. They make triangular bunting, learn a song, and make tetrahedrons from drinking straws.  

On the day itself, you set up the school hall with a range of ‘zones’ so that children and parents can do mathematical craft, colouring and making or relax together with mathematical activities. One zone will involve creating a large, very mathematical structure from all those tetrahedrons.

There’s scope to vary and add as much as you like – some schools just use the ideas we suggest, and others add a whole range of extra activities.
