The clips here mainly focus on maths teaching in the secure estate. However, these short clips also show post-16 practitioners and learners in a range of settings engaged in active learning activities. The main aim is to support practitioners to reflect on and develop their practice; several of the clips could also be used to engage relatively reluctant learners. As well as the set of clips set of clips focusing on maths in the Secure Sector there are other sets that focus on GCSE maths and on maths for vocational learners.
