AJMO Preparation for Years 5–6: Build Reasoning Without Rushing Ahead

What should we check before selecting an Advanced course?

A strong report card is encouraging, but inspect a few independent tasks. Can the child compare fractions, distinguish area from perimeter, follow multi-step conditions and explain why a calculation fits? If one prerequisite is weak, repair it directly rather than using a difficult puzzle to teach everything at once.

AJMO’s published upper age limit includes younger students, but age inclusion alone does not tell us whether a particular child will enjoy the challenge. Start with appropriate official samples and ask how they approached them.

What does a useful short session look like?

1. Reconnect: spend a few minutes recalling one mathematical idea.
2. Investigate: allow an independent attempt at an unfamiliar task.
3. Discuss: compare the child’s representation with a worked approach.
4. Change: attempt a related task with one condition altered.
5. Remember: write one sentence about the useful method.

As a starting experiment, keep a session around 20–30 minutes and stop before fatigue dominates. That is a suggested learning routine, not a promise about preparation hours or results. Extend productive investigation when the child wants to continue; shorten it if the task is inaccessible.

How can we train strategy without accelerating every topic?

Original example: a child makes a pattern with 4 tiles in the first row, 7 in the second and 10 in the third. If each row increases by 3, how many tiles are in row 8? Build a row-number table before calculating. Row 8 has 4 + 7 × 3 = 25 tiles.

The interesting mistake is using 8 increases instead of 7. Ask the child to compare rows 1 and 2: there is one increase between two rows. Checking this small case supports the general method.

Now give 34 tiles and ask which row it is. Subtract the initial 4, divide the remaining 30 by 3 to find 10 increases, then add 1: row 11. Working backwards uses the same relationship in a different direction.

What should parents praise and record?

Record “made a table without a hint”, “checked the first row” or “explained the seven increases.” These are visible behaviours the child can repeat. Praise a useful revision of an idea as well as a correct answer.

Keep a brief error notebook with three columns: my first idea, what failed, what I will check next time. Avoid filling it with copied full solutions. Revisit a fresh task later to see whether the new habit survives.

When does AMC Y5–6 Advanced make sense?

It is an option when basic school mathematics is secure and the child needs structured work on more demanding problem-solving. Inspect the actual curriculum and starter lessons before deciding. The course covers the Australian AMC pathway and related techniques; it is not an official AJMO course or competition entry.

Do not jump to a Year 7–8 or AIMO label merely because a younger child is quick at routine calculations. If they are already solving and explaining harder samples independently, discuss the appropriate stretch with their teacher and inspect the deeper curriculum.

Read why school maths and unfamiliar problems feel different if you are deciding what kind of help your child needs. The original strategy examples offer a practical place to begin.
