NRICH, a product of the collaboration between the Faculties of Mathematics and Education at the University of Cambridge, aims to enrich the mathematical experiences of Pre-K to 12th-grade learners by providing thousands of online resources that are free and accessible to all. The site features a large collection of award-winning materials that make it possible for students to work at home independently while schools are closed and for teachers to use when planning for e-learning. For teachers and parents planning lessons, NRICH offers free curriculum-linked resources for use in the Pre-K, primary, and secondary levels. For students, the site features live games that students can submit solutions for. There are also student accessible resources and games available for independent practice.
