Most maths competitions are an hour in an exam room. The Maths Challenge is different: a few problems, several weeks to work on them, a partner or small group to think with, and written solutions that a teacher marks. That format rewards something many capable students have never been taught, which is how to write a full mathematical argument rather than just an answer. This page explains the Australian Maths Trust's program, which used to be called the Mathematics Challenge for Young Australians, sets out the 2026 dates and scoring from the Trust's own pages, and works through one original problem to show how a complete solution earns marks that an answer alone does not.

In short
Maths for Young Australians is the Australian Maths Trust's problem-solving program, previously the Mathematics Challenge for Young Australians. Its Maths Challenge module runs for 3 to 4 weeks for Years 3 to 10, with students working in pairs or small groups on 4 or 6 problems, each worth 4 marks, and writing worked solutions that teachers mark. In 2026 it ran between 2 March and 26 June.
For the Maths Challenge
Reasoning for primary students, problem-solving depth for the middle years, and competition training for the keenest.

The Trust describes Maths for Young Australians as a modular program. These details come from its program page, read on 7 October 2026.
| Module | Who it is for | Length |
|---|---|---|
| Maths Challenge | An introductory module for students in years 3 to 10, working individually or in small groups | 3 to 4 weeks, between March and June |
| Maths Enrichment | More advanced students in years 4 to 10 | 12 to 16 weeks, flexibly between April and September |
| Australian Intermediate Mathematics Olympiad | An open contest, generally for students who have done well in the Challenge or Enrichment | A 4-hour contest |
The Trust states that "the Maths for Young Australians program was previously known as the Mathematics Challenge for Young Australians (MCYA)". Many parents and teachers still use the old name, which is why both appear on this page.
The modules "can be taken independently of each other or as a progressive course", in the Trust's words. A student can do the Challenge alone, or treat it as the first step towards Enrichment and the olympiad.
Schools enter and run the modules. Teachers receive the problem booklets and teacher guides, run the sessions and mark the work. Fees are set in Australian dollars by the Trust, so we do not quote them.
The program also matters for later invitations. The Trust's olympiad page says that students need "outstanding results in the Australian Mathematics Competition or one of the three modules under Maths for Young Australians" to be considered for maths training by invitation.

Maths Challenge in detail
From the Trust's Maths Challenge page, read on 7 October 2026.
| Detail | Primary divisions | Secondary divisions |
|---|---|---|
| Divisions | Middle Primary (Years 3 and 4), Upper Primary (Years 5 and 6) | Junior (Years 7 and 8), Intermediate (Years 9 and 10) |
| Problems | 4 problems, worked solutions | 6 problems, worked solutions |
| Marks | 4 problems of 4 marks: 16 marks | 6 problems of 4 marks: 24 marks |
| Working arrangement | Groups of three are encouraged | Groups of two are encouraged |
| Awards | Distinction 14 to 16, Credit 10 to 13, Proficiency 6 to 9 | High Distinction top 10 per cent, Distinction next 15, Credit next 25 |
In 2026 the Challenge ran from Monday 2 March to Friday 26 June, with entries closing on Friday 22 May. The Trust says it is designed to run over 3 to 4 weeks, with around 1 hour of class time and 2 to 3 hours of study time per week. Topics "vary from year to year, based on the national maths curriculum".
Marking is done by teachers, with the Trust's detailed marking guide, and results are submitted online; the Trust can mark at extra cost. It notes that "students' understanding of the problems is enhanced when teachers mark the student submissions and use the materials provided to give feedback."
Every student receives a certificate at some level. In the secondary divisions, cut-off scores are set by comparing students in the same year level and region, so they move from year to year.
The Trust publishes sample problems and sample solutions for each division. They are the clearest place to see what a full solution looks like, and we point students to them rather than reproducing them.

How solutions earn marks
Each Challenge problem is worth 4 marks, and the work is written, not ticked. The difference between 1 mark and 4 is almost always the explanation. Here is an original problem of ours, a rubric we use in class, and three answers marked against it.
A post office sells only 3c and 5c stamps. Which amounts from 1c to 20c cannot be made exactly, using any number of each stamp? Explain why every amount above your largest impossible one can be made.
The answer is 1, 2, 4 and 7. We checked it by listing every combination; the reasoning a student writes should not depend on a computer, which is where the marks come from.
List the amounts systematically: 3, 5, 6 (3 plus 3), 8 (3 plus 5), 9, 10, 11 (6 plus 5). Checking 1 to 10 one by one shows 1, 2, 4 and 7 cannot be made.
Then the key step: 8, 9 and 10 can all be made, and they are three amounts in a row. Adding one more 3c stamp to each gives 11, 12 and 13, then 14, 15 and 16, and so on for ever. So every amount from 8 upwards can be made, and 7 is the largest impossible amount.
| Rubric point | Mark | Answer A: "1, 2, 4, 7" | Answer B: list to 20, no argument | Answer C: full solution |
|---|---|---|---|---|
| Correct list of impossible amounts | 1 | Yes | Yes | Yes |
| Systematic check of small amounts shown | 1 | No | Yes | Yes |
| Notices three consecutive makeable amounts | 1 | No | No | Yes |
| Explains why adding 3c covers every larger amount | 1 | No | No | Yes |
| Total | 4 | 1 of 4 | 2 of 4 | 4 of 4 |
Answer B is the most common in our classes: correct, careful, and still missing half the marks, because checking up to 20 does not show that 21, 22 or 100 can be made. The marking rubric is ours, written for teaching, and the Trust's own marking guide may divide marks differently. The lesson carries across both: in a written challenge, the argument is the answer.
Problem, rubric and marked answers are ours. The impossible amounts 1, 2, 4 and 7 were confirmed by enumeration in Python on 7 October 2026. The AMT's marking guide is supplied to teachers and is not reproduced here.
The next module
Students who enjoy the Challenge often move on to Enrichment, a longer extension course with its own stages.
| Stage | General recommendation | Scoring |
|---|---|---|
| Ramanujan | Australian Years 4 and 5 | 8 problems of 4 marks, 32 marks |
| Newton | Australian Years 5 and 6 | 8 problems of 4 marks, 32 marks |
| Dirichlet | Australian Years 6 and 7 | 8 problems of 4 marks, 32 marks |
| Euler | Australian Years 7 and 8 | 10 problems of 4 marks, 40 marks |
| Gauss | Australian Years 8 and 9 | 10 problems of 4 marks, 40 marks |
| Noether | Capable or very capable Years 9 and 10 | Not listed with the others on the page read |
| Pólya | Top 10 per cent of Year 10 | Not listed with the others on the page read |
In 2026 Enrichment ran from Monday 30 March to Friday 16 October, with entries closing on Friday 24 July. The Trust says it is designed to run over 12 to 16 weeks, with around 1 hour of class time and 2 to 3 hours of individual study time per week, and that its material "develops mathematical concepts not covered by the standard curriculum".
The Trust notes that stages "are not limited to school years", so a strong Year 5 student might begin at a higher stage. Schools decide placements.
Each student receives a Student Notes book with a structured extension course and a Student Problems booklet. The later stages include topics such as modular arithmetic, Diophantine equations, methods of proof, functional equations and graph theory.
Our competition maths classes prepare students for the kind of thinking Enrichment expects, through our own problems. We do not work on the Trust's booklet problems with students during the module; that work belongs to the student and their school.

From answers to arguments
Most students can find answers long before they can explain them. These steps close that gap.
| Step | What the student does | The sign it is secure |
|---|---|---|
| 1. Show the search | Writes the cases tried, not just the result | A reader can follow how the answer was found |
| 2. Spot the structure | Looks for a pattern behind the cases | Names the pattern in a sentence |
| 3. Argue for all cases | Explains why the pattern always holds | The argument works beyond the cases listed |
| 4. Check and tidy | Reads the solution as a stranger would | No step relies on something unwritten |
Talking the solution through out loud first, then writing what was said, helps most students.
Working with a partner, as the Challenge encourages, makes explaining natural.

Questions about the Maths Challenge
It is the old name for the Australian Maths Trust's Maths for Young Australians program. Its Maths Challenge module gives students in Years 3 to 10 a few problems to solve over 3 to 4 weeks, with written solutions marked by teachers.
Four in the primary divisions and six in the secondary divisions, each worth 4 marks, for totals of 16 and 24 marks.
The Trust encourages groups of three in primary divisions and groups of two in secondary divisions, although students can also work individually.
In 2026 it ran between Monday 2 March and Friday 26 June, with entries closing on Friday 22 May. Check the Trust's page for the next year.
Teachers, using the Trust's marking guide, then results are submitted online. The Trust can mark submissions at an extra cost.
A list of the points a full solution must contain, with marks for each. Ours shows why a correct answer without an argument earns only part of the marks.
A longer module of 12 to 16 weeks for more advanced students, in stages from Ramanujan, recommended for Years 4 and 5, to Pólya, for the top 10 per cent of Year 10.
Not with the live problems: they are the student's own work. We teach problem solving and written argument with our own problems, before and around the module.
Schools enter and run the modules. Ask your child's maths teacher or coordinator.
No. We are an independent online school; the details here come from the Trust's pages.
