To get the most out of the programme, it is helpful to examine some of the key themes.  Watch these introductions and lesson extracts (by clicking the dropdowns below) with colleagues to consider where these concepts feature in the recorded sessions and reflect on how they are used in your practice.  These videos supplement the live training provided by the NCETM.
