GCSE Mathematics and Numeracy

This double award is assessed by three written papers, one of them non-calculator, covering number, algebra, geometry and measures, statistics and probability, with Unit 1 given over to financial mathematics in real-world contexts. Literacy matters more than many expect: every paper sets questions in written context and awards two marks for communicating, organising and writing accurately, so learners must read problems closely and explain their working in words. The biggest thing Key Stage 3 should build is solving multi-step worded problems from real contexts, with every step explained and a written conclusion.

Links with other qualifications

The finance, percentage, compound measure and statistics content overlaps heavily with Business, Geography, Social Studies and The Sciences, so agreeing shared methods for percentages, graphs and units with those departments will reinforce Key Stage 3 teaching.
