1. Developing Mastery in Maths

2. What is mastery? Deep and sustainable learning
The ability to build on something that has already been sufficiently mastered
The ability to reason about a concept and make connections
Fluency
2 outcomes for connections: deepen conceptual mathematical understanding; complete in fewer steps
Conceptual fluency e.g. column addition has with secure understanding of number bonds and place value – key to everyone

3. “Keep up, not catch up!”
In essence, all children need a deep understanding of the
mathematics they are learning so that:
Future mathematical learning is built on solid foundations which do not need to be re-taught
There is no need for separate catch up programme due to some children falling behind
There will be small group pre-teach and consolidation groups for some children
Children who can often fall a long way behind are better able to keep up with their peers so that gaps in attainment are narrowed whilst the attainment of all is raised

4. How is depth achieved? Longer time on topics
Detail in exploring the concept – all aspects exposed and linked
Small steps
Questioning and activities develop reasoning and make connections

5. What’s Changed?
Mixed ability classes – starting in Year 3, and to follow this year group through their school life
Regular change of talk partner
Emphasis on using concrete resources and pictures before moving onto abstract ideas.
Children to explain their reasoning and understanding of Mathematics
More focus on precise vocabulary
