Teacher Guide

Below is a guide to using the NRICH website on Desktops and tablets, a mobile phone guide will be available soon.

The only way to learn mathematics is to do mathematics.
Paul Halmos

NRICH promotes the learning of mathematics through problem solving.

At NRICH we believe that:
  • Our activities can provoke mathematical thinking.
  • Students can learn by exploring, noticing and discussing.
  • This can lead to conjecturing, explaining, generalising, convincing and proof.
  • In a classroom, the students' role is to focus on the mathematics while the teacher focusses on the learners.
  • The teacher should aim to do for students only what they cannot yet do for themselves.

Curriculum Mapping

We aim to help teachers embed problem solving into the curriculum. Curriculum mapping guides and detailed teachers’ notes support your planning and help you to promote rich mathematical thinking in the classroom.

Using NRICH resources will help schools to implement Ofsted’s recommendation to ‘increase problem solving across the curriculum’.

Professional Development

The NRICH team offers bespoke CPD sessions to help you develop rich mathematical learning opportunities for all primary or secondary students. For more details, please see our information about bespoke CPD led by the Primary NRICH team or the Secondary NRICH team.

In addition, NRICH holds professional development events for teachers each year in Cambridge, and contributes to teacher sessions run by other organisations such as UKMT. Details of current CPD event opportunities can be found on our Events page.
