The 5 Big Ideas of Maths Mastery
Lessons are broken down into small connected steps that gradually unfold the concept, providing access for all children and leading to a generalisation of the concept and the ability to apply the concept to a range of contexts.
Representations used in lessons expose the mathematical structure being taught, the aim being that students can do the maths without recourse to the representation.
If taught ideas are to be understood deeply, they must not merely be passively received but must be worked on by the student: thought about, reasoned with and discussed with others.
Quick and efficient recall of facts and procedures and the flexibility to move between different contexts and representations of mathematics.
Variation is twofold. It is firstly about how the teacher represents the concept being taught, often in more than one way, to draw attention to critical aspects, and to develop deep and holistic understanding. It is also about the sequencing of the episodes, activities and exercises used within a lesson and follow up practice, paying attention to what is kept the same and what changes, to connect the mathematics and draw attention to mathematical relationships and structure.
The Five Big Ideas were first published by the NCETM in 2017.
