Year 9 Advanced Maths, mapped to the NSW syllabus.
The complete NSW Year 9 Advanced Mathematics course — every topic, every subtopic, every question with a fully worked solution. Authored by an experienced Australian maths teacher and aligned to the NESA Mathematics K–10 Syllabus (2022) at Stage 5.
What Year 9 Advanced students learn in NSW
Year 9 is the first year of Stage 5 under the NSW Mathematics K–10 Syllabus (2022), published by the NSW Education Standards Authority (NESA). Stage 5 is built from Core outcomes that every student studies and Path outcomes that prepare students for the more demanding Year 11 and 12 courses. Year 9 Advanced covers the Core in greater depth and adds Path content such as surds and fractional indices, factorising quadratics, congruence proofs, networks, and the graphs of parabolas and circles.
The 14 topics below cover the three NESA strands — Number and Algebra, Measurement and Space, and Statistics and Probability — with the Working Mathematically outcome (MAO‑WM‑01) running through all of them. Each topic shows its NESA outcome codes, and every one of the 2,180 questions has a fully worked solution.

About Stage 5
Stage 5 spans Years 9 and 10. NESA does not set which topics belong to each year — schools decide how to split the content. Its Stage 5 outcomes are either Core (codes such as MA5‑TRG‑C‑01) or Path (codes such as MA5‑IND‑P‑02). Year 9 Advanced covers the Core outcomes in greater depth and adds Path content: surds and fractional indices (MA5‑IND‑P‑02), factorising quadratics (MA5‑ALG‑P‑01 and MA5‑ALG‑P‑02), congruence proofs (MA5‑GEO‑P‑02) and parabolas and circles (MA5‑NLI‑P‑01). Some subtopics first revise Stage 4 ideas, such as Pythagoras' theorem (MA4‑PYT‑C‑01), and are labelled with the Stage 4 code. Year 10 Advanced then takes the Path content further.
Why Class Mathematics for NSW Year 9 Advanced Maths

Frequently asked questions
Does Class Mathematics follow the 2022 NSW syllabus?
Yes. Class Mathematics is aligned to the NSW Mathematics K–10 Syllabus (2022), the current syllabus published by NESA. Every Year 9 Advanced topic maps to Stage 5 outcome codes, or to the Stage 4 code it revises — for example, Trigonometry maps to MA5‑TRG‑C‑01 and MA5‑TRG‑C‑02, and Quadratics covers MA5‑ALG‑P‑02 and MA5‑EQU‑P‑01.
What is the Working Mathematically outcome (MAO-WM-01)?
Working Mathematically (MAO‑WM‑01) is the outcome that runs through every topic in the NSW Mathematics K–10 Syllabus. It is about communicating reasoning, building fluency and understanding, and solving problems. Rather than being a separate topic, it is built into all of them, and every worked solution on Class Mathematics shows these steps.
What topics are covered in NSW Year 9 Advanced Maths?
NSW Year 9 Advanced Maths covers 14 topics across three NESA strands: Number and Algebra (working with numbers, algebra: expanding and factorising, indices and scientific notation, equations, earning money, coordinate geometry and graphs, quadratics), Measurement and Space (Pythagoras' theorem, trigonometry, properties of geometric figures, surface area and volume, congruence and similar figures), and Statistics and Probability (probability, investigating data).
What is the difference between Year 9 Core and Year 9 Advanced?
Year 9 Core concentrates on the Stage 5 Core outcomes. Year 9 Advanced covers the same Core content in greater depth and adds Path outcomes, such as surds, negative and fractional indices, factorising quadratics, congruence proofs, networks, parabolas and circles. It suits students aiming for Mathematics Advanced or Extension 1 in Years 11 and 12.
How many topics and questions are in the Year 9 Advanced course?
There are 14 topics in NSW Year 9 Advanced Maths, divided into 109 subtopics with 2,180 practice questions — 20 in every subtopic. Every question includes a fully worked solution to support independent learning.
What is the hardest topic in Year 9 Advanced Maths?
Many students find Algebra: Expanding and Factorising and Quadratics the most demanding, because there are several factorising methods and choosing the right one takes practice. Trigonometry is also new in Year 9. Regular practice with worked solutions builds confidence in all of these.
How can parents help their Year 9 child with maths?
The most effective help is regular, structured practice that follows the NSW syllabus. Parents don't need to teach the content themselves — the worked solutions guide students through each problem. Short sessions of 20–30 minutes several times a week work better than long, occasional ones.
