For Schools

Why don’t we celebrate maths in schools in the same way we celebrate other subjects?

Maths on Toast’s Festival of Triangles offers you the chance to run a community maths event at your primary school. Watch the video below to find out more.

What is Festival of Triangles?

Festival of Triangles is a week-long event involving a series of activities in the classroom, culminating in an after school or weekend community event to which parents, carers, children and teachers are invited.

It’s a mix between a school fair, a school performance and a whole week full of creative maths lessons.

At the event, children’s work is assembled into a giant mathematical structure, while parents and children carry out more creative maths activities.

Here is a giant Sierpinski tetrahedron from Haseltine Primary School’s Festival of Triangles event. It’s made from 256 tetrahedrons, all made from bendy straws by different children in the school and it’s about 2m tall.

Why should I run Festival of Triangles at my school?

We’ve found over the years that parents (contrary to some peoples’ expectations!) are really keen to get involved with their children’s maths, just they are often anxious about it themselves and not sure where to start. So, we developed Festival of Triangles.

Here are some reasons we think your primary school would benefit:

  • People remember the event as an enjoyable maths experience
  • Parents feel more confident to engage with their children’s mathematical ideas
  • Parents feel more confident to speak to teachers about maths
  • Families enjoy doing maths together
  • Parents and children engage in mathematical activities, by showing concentration and perseverance and broadening their view of what maths is
  • For teachers, it can broaden your leadership and development skills
  • It shows inspectors how you and your school are willing to engage with parents

How do I run a Festival of Triangles event in my school?

Maths on Toast will provide you with a comprehensive Festival of Triangles kit. The kit, and the accompanying resources, will take you through the planning process, explain what to do on the day, and even start you thinking about what you can do to follow up and consolidate learning.
