GCSE Mathematics and Numeracy
Mae disgrifiadau'r TGAU yn Saesneg yn unig, gan eu bod wedi eu cymryd 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 Cynrychioli data
-
Drawing graphs, charts and diagrams
Learners construct pictograms, bar charts, pie charts, line graphs, scatter diagrams with lines of best fit and grouped frequency diagrams, and draw conversion and travel graphs, with Higher Tier adding cumulative frequency, box plots and histograms.
Rhifedd: Cynrychioli data
Paratoi disgyblion
- Blwyddyn 7
- Pupils draw bar charts and pie charts by hand from their travel-to-school data, choosing a suitable scale and labelling both axes.
- Blwyddyn 8
- Pupils draw a conversion graph between pounds and euros and a travel graph of a walk to Dare Valley Country Park, then read values from each.
- Blwyddyn 9
- Pupils measure arm span and height, plot a scatter diagram, draw a line of best fit through the mean point and describe the correlation.

Cam cynnydd 3
Rwy'n gallu dewis a llunio siartiau, diagramau a graffiau priodol sydd â graddfeydd addas.
Rwy'n gallu cynrychioli data gan ddefnyddio:
- rhestrau, siartiau cyfrif, tablau, diagramau a thablau amlder
- siartiau bar, siartiau data wedi'u grwpio, graffiau llinell a graffiau trawsnewid
- pictogramau lle mae un symbol yn cynrychioli mwy nag un uned gan ddefnyddio allwedd
- diagramau Venn a Carroll.
Cam cynnydd 4
Rwy'n gallu creu tablau amlder ar gyfer setiau o ddata mewn cyfyngau dosbarth hafal, gan ddewis grwpiau fel y bo'n briodol.
Rwy'n gallu llunio a dehongli graffiau a diagramau (gan gynnwys siartiau cylch) i gynrychioli data arwahanol neu barhaus, gan ddewis graddfa briodol.
Rwy'n gallu llunio graffiau i gynrychioli data gan gynnwys diagramau gwasgariad er mwyn ymchwilio i gydberthyniad.

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 TGAU 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.
