Geometry, Pythagoras and trigonometry
GCSE Mathematics knowledge mat
Label It, Then Choose
How you know which of sin, cos and tan you need, and why doubling a shape’s lengths multiplies its volume by eight. Pythagoras both ways round; labelling a triangle from the angle and choosing a ratio, with the exact values Paper 1 expects; angle facts, three circle theorems and similar-shape scaling; the six Appendix results you must know unprompted; a ladder problem worked with trigonometry. Nine terms to define, a model answer on similar cylinders, and the misconceptions that cost marks.

Everything else this site has for Mathematics: Mathematics teaching resources
One landscape A4 page on one topic, built around one idea a class can hold onto. It carries Pythagoras both ways, choosing a trig ratio from the angle, angle facts, three circle theorems, similar-shape scaling, the Appendix results and a worked ladder problem. Then the vocabulary, a worked exam-style answer and the misconceptions that cost marks.
No photographs, on purpose: there is no archival photograph of a percentage, and a stock image of a calculator would make the sheet worse. Every figure is drawn in code for the sheet (a bar model, a graph, a tree diagram), so nothing on it is licensed from anybody and nothing is AI-generated. Every claim is sourced to the DfE subject content and its Appendix of formulae, and nothing is reproduced from a past paper, a textbook or a specification.
Sold by subject: all four mathematics sheets for one price. A knowledge organiser stores a unit and is revised from afterwards; this is meant to be on the table while the work is happening.
- Written to
- The DfE GCSE mathematics subject content (DFE-00233-2013) and its Appendix of formulae. No photographs: every figure is drawn in code for the sheet, so nothing on it is licensed from anybody
