The Problem-solving Classroom: the Teacher's Role

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.
