Charlie Gilderdale is the Secondary Coordinator of the NRICH Project, based at both the Faculty of Education and the Faculty of Mathematics in the University of Cambridge.

Charlie was an undergraduate at the the University of Cambridge and then completed a PGCE in Secondary Mathematics before becoming a mathematics teacher and then Head of Department at a secondary school in Cambridgeshire. He has worked at the University for the last 25 years, first training secondary mathematics teachers, and then as a member of the NRICH Project, where his work has focussed on problem solving and on creating opportunities for learning mathematics through exploration and discussion.

Charlie is responsible for developing resources for secondary students that aim to enrich their experience of mathematics and challenge them to think mathematically. He also develops "rich tasks” and resources for secondary teachers that are linked to the secondary school curriculum. To support teachers he has created a collection of articles on rich mathematical tasks and how they can be used in the classroom. He continues to work in secondary schools with students and mathematics teachers.

Charlie is a member of The Mathematical Association, and The Association of Teachers of Mathematics, and has run Professional Development courses for teachers in the UK and abroad (India, UAE, Pakistan, Sri Lanka, Vietnam, Hong Kong, Malaysia, South Africa, Egypt, Spain, Chile, Argentina). He has supported and contributed to the work of various organisations, including NAGTY, QCA, Royal Institution, Cambridge Assessment, UKMT, Cambridge International Examinations, The Prince's Teaching Institute, HeyMath!, the Association of Teachers of Mathematics and the Mathematical Association.
