Number and Algebra
Money mathematics, index laws and the algebraic machinery that Year 9 assumes: expanding, solving and graphing.
- Percentage increase and decrease
- Profit, loss, discount and GST
- Simple interest
NSW Mathematics Stage 4 (Year 8) syllabus strands, expressed in Dux teaching language. Dot points are our own phrasing, not syllabus prose.
Dux tracks each dot point separately, so “I did Mathematics Year 8” becomes a list of specific things you can already do and specific things you have never been asked. Open a module for all of its dot points, written out.
Money mathematics, index laws and the algebraic machinery that Year 9 assumes: expanding, solving and graphing.
Pythagoras, circles and surface area, plus the congruence reasoning that makes geometric argument possible.
Sampling and display choices, comparing data sets properly, and probability with more than one step.
A Mathematics Year 8 paper is not one question type repeated. Each command word asks for a different shape of answer, and each is worth a different number of marks.
| Command word | Question type | Marks |
|---|---|---|
| calculate | Multiple choice | 1 |
| calculate | Calculation | 2–4 |
| explain | Short answer | 2–3 |
| identify | Multiple choice | 1 |
| justify | Extended response | 4–6 |
| solve | Calculation | 3–5 |
Year 8 Assessment Task Shape — 50 marks, 75 minutes. Practice papers in Dux are assembled to this shape rather than invented, so the timing is training too.
Diagnostic first, then questions written in the shape this course uses. Written answers come back marked against the bands, not just scored.
