This sequence of tasks, part of our feature The Problem-solving Classroom, offers an approach to teaching mathematics that exemplifies a model of 'exporation, codification, consolidation' (Ruthven, 1989). For more information, please see the article included in the above feature.
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.
