NRICH's award-winning resources are free and open to everyone, but our rich mathematical activities require a huge investment of time and expertise to create.
NRICH is part of the Millennium Mathematics Project at the University of Cambridge. We receive no government funding - our work is made possible by donations and grants from organisations and individuals who share our commitment to giving all students access to a rich, imaginative mathematics education.
If you value NRICH, would you consider supporting us by making a donation? Whether your contribution is big or small, your generosity will help us to keep developing engaging, challenging, rewarding mathematics resources to support millions of teachers and students worldwide.
How to give:
For UK and international supporters: donate via the University of Cambridge's secure philanthropic giving page
You can donate online to NRICH through the University of Cambridge's secure philanthropic giving site. The whole of your donation will go directly to supporting NRICH, with no deductions. This also allows the option to apply Gift Aid to your donation if you wish, making your gift worth even more to us at no extra cost to you.
