Year 9 Core Maths, mapped to the NSW syllabus.
The complete NSW Year 9 Core Mathematics course: 13 topics, 78 subtopics and 1,560 questions, every one 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 Core students learn in NSW
Year 9 is the first year of Stage 5 under the NSW Mathematics K–10 Syllabus (2022), published by NESA, the NSW Education Standards Authority. Year 9 Core starts by revising the Stage 4 skills that later work depends on, such as Pythagoras' theorem, fractions, percentages and the angle facts, then moves into new Stage 5 ideas: trigonometry, the index laws, scientific notation, coordinate geometry, simple interest, earning money and comparing data.
The 13 topics below cover the three NESA strands: Number and Algebra, then Measurement and Space, and finally Statistics and Probability, with the Working Mathematically outcome (MAO‑WM‑01) running through all of them. Each topic shows its NESA outcome codes. Most subtopics sit under Core outcomes; a few, such as surds, reach into Path content and show a Path code. All 1,560 questions have fully worked solutions.

About Stage 5
Stage 5 spans Years 9 and 10. NESA does not set which topics belong to each year, so schools decide how to split the content. The 13 topics above are the Year 9 part of the Core course, with Stage 4 revision where it helps. Year 10 Core then moves on to topics such as quadratics, non-linear relationships (MA5‑NLI‑C‑01) and bivariate data (MA5‑DAT‑C‑02). Students who need more depth, or Path content for Mathematics Advanced in Year 11, can take Year 9 Advanced Maths instead.

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 Core topic maps to outcome codes: for example, Trigonometry maps to MA5‑TRG‑C‑01, and Straight Line covers MA5‑LIN‑C‑01 and MA5‑LIN‑C‑02.
What is the difference between Year 9 Core and Year 9 Advanced?
Both courses cover Stage 5 in Year 9. Year 9 Core is built on the Core outcomes that every NSW student is expected to meet, with revision of key Stage 4 skills. Year 9 Advanced works through Core content at greater depth and adds the Path content that prepares students for Mathematics Advanced and Extension in Year 11.
What do Core and Path mean in the Stage 5 syllabus?
Core outcomes, with codes ending in C such as MA5‑FIN‑C‑01, describe what all Stage 5 students should learn. Path outcomes, with codes ending in P such as MA5‑PRO‑P‑01, are extra content for students heading to particular Year 11 courses. Year 9 Core includes a few Path subtopics, and each one shows its Path code.
What topics are covered in NSW Year 9 Core Maths?
NSW Year 9 Core Maths covers 13 topics across three NESA strands: Number and Algebra (working with numbers, expanding and factorising, indices and scientific notation, equations, earning money, straight-line graphs), Measurement and Space (Pythagoras' theorem, trigonometry, surface area and volume, properties of geometric figures, similar figures), and Statistics and Probability (probability, investigating data).
How many topics and questions are in the Year 9 Core course?
There are 13 topics in NSW Year 9 Core Maths, divided into 78 subtopics with 1,560 practice questions, 20 in each subtopic. Every question includes a fully worked solution to support independent learning.
What is the hardest topic in Year 9 Core Maths?
Many Year 9 students find Trigonometry the most challenging topic, because sine, cosine and tangent are completely new and each problem needs the right ratio chosen first. Algebraic fractions and index laws are also common sticking points. 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, because the worked solutions guide students through each problem. Short sessions of 20–30 minutes several times a week work better than long, occasional ones.
