Mastery Sustaining - Developing Fluency at KS3

Developing Fluency with multiplicative reasoning in Key Stage 3 

Type: Work Group For: Secondary teachers of maths

Time: 2 half days and 4 online twilights run by your local work group lead.

          6 additional sessions run centrally by NCETM

Cost: Free of charge

The aim of this Work Group is that schools will continue to reflect upon and develop teaching for mastery approaches within their own school as part of the Angles Maths Hub mastery community. It is envisaged that the subject leader and other members of the department will also contribute to the Work Group activity.  

Focus on multiplicative reasoning 

Multiplicative reasoning encompasses many topics at Key Stage 3 from ratio and proportion to similar shapes continuing into trigonometry in Key Stage 4. This Work Group helps teachers work with their pupils on strategies to look at different contexts and key representations of mathematics. Teachers and their departments will have access to classroom resources that are designed to help pupils make connections and recognise relationships. Key features of the programme include the area model and embedding a double number line and ratio table within their classroom practice. 

What will participating schools gain? 

Participating in this Work Group will give teachers and schools the opportunity to review and improve the quality of teaching & learning in many topic areas by exposing strategies to embed fluency and automaticity within the classroom.  

The fluency arm of Mastery Sustaining aims to develop teachers’ depth of subject knowledge and classroom practice. The aim is for Work Group participants to disseminate learning to others in their department through lesson study and use of department time. 


Professional learning: 

In this Work Group, participants will: 

  • Develop a deeper insight into the structure that underpins Maths at Secondary 

  • Develop an understanding of key issues and misconceptions behind multiplicative reasoning 

  • Deepen their own subject knowledge and awareness of connections within the curriculum. 

Practice development: 

Participants will explore key strategies to develop fluency and use classroom resources with their pupils. They will use and evaluate these strategies to start to build more automaticity across KS3. 


For this Work Group, schools should aim to provide one or two teachers to attend training and work together within their department. There will be 6 sessions throughout the year, with 2 in person.
