This material was used in one of the series of CPD workshops that formed the four day course ‘Leading and supporting the development of digital technologies in mathematics’. This course, delivered in two sets of two-day sessions, was funded by the NCETM and written and tutored by members of the Association of Mathematics Education Teachers (AMET) and National Association of Mathematics Advisors (NAMA). Over 50 people followed the course with representatives from the ITE sector, Local Authorities and teachers from schools (primary, secondary and further education).
