The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to embed rich mathematical tasks into everyday classroom practice. More information on many of our other activities can be found here.

On this website you will find thousands of our free mathematics enrichment materials (problems, articles and games) for teachers and learners from ages 5 to 19 years. All the resources are designed to develop subject knowledge, problem-solving and mathematical thinking skills. The website is updated with new material on the first day of every month.

For guidance on how to find the right resources for you, go to the Help section of the site.

This month







This month's mathematical theme is Visualising:

Our problems involve visualisation, inviting you to reflect on how you "see" mathematics. Everyone imagines a problem in a different way. By sharing our personal visualisations it can deepen our own understanding of the mathematics within a problem, and help us to make sense of someone else's route to a solution.

The Teachers' Notes accompanying each problem are there to help give teachers an insight into how Visualising might be promoted in their classrooms and lead to rich mathematical activity and discussion. A list of the themes of previous issues can be found here .

Solutions to the October problems will appear in November.
