The Jurassic Maths Hub runs Primary Work Groups which include national Teaching for Mastery programmes, Specialist Knowledge for Teaching Mathematics (SKTM) programmes and Research and Innovation projects.  All Work Groups are intended to provide high quality professional development opportunities developing teachers as researchers of classroom practice. The focus is on giving all pupils access to equitable classrooms; classrooms where pupils can all participate and be influential, and classrooms where pupils are encouraged and supported to develop a deep, connected and sustained understanding of the mathematics being explored. This reflects the Jurassic Maths Hub approach to Teaching for Mastery.
