NRICH's award-winning resources are free and open to everyone, but our rich mathematical resources 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.
We are committed to keeping NRICH resources freely available, but we need to find further funding to secure our future and help us continue to develop and improve the site for our users.
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.
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.
If you are a US taxpayer you may prefer to donate via Cambridge in America. Cambridge in America is a 501(c)(3) tax-exempt organisation (recognised by the US Internal Revenue Service) which funds grants that benefit Cambridge University and its member colleges and departments. Gifts to Cambridge in America qualify for an income tax deduction to the limits allowed by law.
You can give online via the Cambridge in America secure online gift form. Please state when making your gift that you would like your donation to support 'NRICH (Millennium Mathematics Project)'.
Thank you for your support!
