Year 9 Maths practice, done properly
Year 9 is the year the syllabus starts pointing at senior maths. Trigonometry arrives, algebra moves from linear to non-linear, and index laws extend to negative and zero powers. Questions stop being solvable by recognising a type and start requiring a method to be chosen — which is why Year 9 is where confident students often first find maths hard.
This page gives you 600 Australian Curriculum Maths questions for Year 9, organised into 15 graded tests that climb from Foundation to Extension. Test 1 is free in full — no card, no account.
What Year 9 Maths covers
The 6 areas the Year 9 bank is built from, in the proportion the questions actually fall:
Year 9 Maths explained, topic by topic
1. Algebra and patterns
Expanding binomial products, factorising quadratics, simplifying algebraic fractions, and the gradient-intercept form of a straight line. Non-linear relationships — parabolas and simple exponentials — are graphed and described. Factorising is the skill Year 10 assumes completely, and the difficulty is that it runs backwards from expanding, so practice at expanding does not by itself produce it.
157 of the 600 Year 9 questions are on this topic.
2. Measurement and geometry
Right-angled trigonometry, surface area and volume of composite solids, and similarity proofs. Trigonometry in Year 9 is less about the ratios than about labelling: opposite and adjacent are defined relative to the angle being used, not to the page, so a diagram rotated from the familiar orientation causes more errors than the calculation ever does.

3. Statistics and probability
Bivariate data, scatterplots, lines of best fit and the language of correlation, alongside two-step probability with and without replacement. Students are asked to interpret rather than compute — to say what a correlation does and does not establish, which is the distinction between association and cause that the curriculum names explicitly at this year.

4. Number and integers
Index laws extended to negative and zero indices, scientific notation for very large and very small quantities, and the first work with surds and exact values. Scientific notation is where accuracy is lost in Year 9: converting is straightforward, and multiplying or dividing two quantities in scientific notation requires the indices and the coefficients to be handled separately, then recombined.

5. Ratios and rates
Rates of change are connected to gradient, direct proportion is expressed algebraically, and similar figures are scaled by ratio in length, area and volume. The area and volume scale factors are the Year 9 trap: doubling every length multiplies area by four and volume by eight, and a question that gives a length ratio and asks for an area ratio is testing exactly that.

6. Fractions, decimals and percentages
Percentage work becomes financial: simple and compound interest, repeated percentage change, and depreciation. Compound interest is the point at which a percentage stops being a single multiplication, and the common Year 9 error is to calculate one year's interest and multiply it by the number of years, which is simple interest wearing a different name.

Try real questions — easy and hard
Tests are graded from a foundation confidence-builder (Test 1, free to try in full) up to genuine extension-level questions by Test 15. Here is one of each, straight from the bank.
Frequently asked questions
Is this Year 9 Maths practice free?
Test 1 for Year 9 Maths is free in full — all 40 questions, every answer explained, no credit card and no account needed. The remaining 14 tests are part of a subscription.
How hard are the tests?
The 15 tests are graded across five tiers, from Foundation to Extension. Test 1 is a confidence-builder pitched at the Year 9 curriculum; by Test 15 the questions are deliberately above level, so a confident student is stretched rather than repeating classwork.
Are the questions aligned to the Australian Curriculum?
Yes. All 600 Year 9 questions are written to the Australian Curriculum v9 Year 9 Mathematics content, across 6 topic areas: algebra and patterns, measurement and geometry, statistics and probability, number and integers, ratios and rates, fractions, decimals and percentages.
Does my child get told why an answer is wrong?
Every option is explained, not just the correct one. A wrong answer tells you which misconception produced it, which is the part that changes what your child does next.
Is this the same as the NAPLAN practice on the site?
No. NAPLAN practice is a timed paper at the real test specification. These are graded practice tests for learning a topic — untimed, fully explained, and organised by difficulty rather than by exam section.
