The cross-cutting capability strand of KS3 Maths. The NC document names this as the bedrock of mathematical learning at this stage — three threads:
- Develop fluency — consolidate numerical and mathematical capability; extend understanding of the number system; move freely between different numerical, algebraic, graphical, and diagrammatic representations
- Reason mathematically — extend and formalise knowledge of ratio and proportion; identify variables and express relations between variables algebraically and graphically; make and test conjectures
- Solve problems — develop mathematical knowledge in part through problem solving; begin to model situations mathematically; select appropriate concepts and techniques to apply to unfamiliar contexts

Direct precursor to KS4 Maths — Mathematical reasoning, problem-solving, and communication.
Why this is its own strand
The NC’s decision to make Working Mathematically a named strand at KS3, rather than just an implicit way of doing maths, is what AQA picks up at KS4 in giving 25–30% of marks to AO2 (reasoning) and AO3 (problem solving). The principle is the same at both stages: thinking mathematically matters as much as applying procedures.
For NEO’s EBSNA cohort, this is also the strand most affected by maths anxiety — it requires confidence to attempt unfamiliar problems and tolerance for partial answers. KS3 work that is secure on this strand is the precondition for moving into KS4 IGCSE Foundation tier with confidence.
