GCSE Mathematics and Numeracy
Mae disgrifiad y cymhwyster yn Saesneg yn unig, gan ei fod wedi ei gymryd o fanyleb Saesneg CBAC.
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.

Sgiliau sy'n defnyddio Perthnasoedd yn y system rif
-
Percentages, ratio and proportion
Learners find fractions and percentages of amounts, calculate percentage change, use multipliers, solve ratio and direct and inverse proportion problems, and at Higher Tier handle repeated proportional change and reverse percentages.

Paratoi disgyblion
- Blwyddyn 7
- Pupils scale a Welsh cake recipe for 6 people up to 15 using ratio, and find 10%, 5% and 15% of shop prices by building from 10%.
- Blwyddyn 8
- Pupils calculate the percentage increase in local bus fares over several years and express one quantity as a percentage of another, such as goals scored out of shots taken.
- Blwyddyn 9
- Pupils use single multipliers such as 0.85 and 1.2 for repeated percentage change, and work back to the original price of an item before a sale.

Da gwybod
- Unit 1 allows a calculator: 'A calculator will be allowed in this paper.' (page 5).
- Unit 2 is non-calculator: 'A calculator will not be allowed in this paper.' It holds all probability and much of the geometry (pages 5 and 10).
- Unit 3 allows a calculator and holds most of the data handling and measures content (pages 5 and 10).
- Two marks on each paper, at each tier, are for 'communicating, organising and writing accurately', six marks across the qualification, 'in addition to the marks allocated to the mathematics'. One mark is for communicating and organising, one for writing accurately, and the questions are clearly indicated on the paper (page 51).
- Writing accurately means learners 'show all their working', 'use correct mathematical form in their working' and 'use appropriate terminology, units, etc.' (page 51).
- Calculators must not offer language translators or hold stored dictionaries, formulas or text, and must not be borrowed from another candidate during the examination (page 52).
- Units 1 and 3 have a formula list at the start of the paper; Unit 2 has none. The Foundation Tier lists give only the area of a trapezium and the volume of a prism, so all other formulae must be recalled (pages 52 to 55).
- Metric to imperial equivalences 'will be given to learners' (Section 3.5.7, page 35), and compasses 'will be required' for some constructions and loci in Unit 3 (Section 3.2.2, page 30).
- There is no NEA. All assessment is by written examination, tiered Higher (grades A* to D) and Foundation (grades C to G), and learners may be entered at different tiers across units (pages 6 and 59).
Cysylltiadau â chymwysterau eraill
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.
