• Mastery PD Materials

Insights from experienced teachers

Pairs of teachers explore small sections of the mastery materials in depth

Insights from experienced teachers

This set of videos models the sort of professional conversations that the materials might stimulate. The conversations occur between pairs of teachers (including experienced Secondary Mastery Specialists) and focus on specific sections of the materials, drawing out the ideas and connections that provoked them to think more deeply.

They also discuss how some of the questions might provoke deeper understanding amongst students in the classroom. We encourage these sort of conversations within maths departments and across schools, both in person and online. All the videos feature online conversations as they were recorded in summer 2020.
