The Australian International School Phnom Penh (AISPP) will host the Phnom Penh Intermediate Math Competition on Thursday, 12 November 2026. According to the school’s Facebook countdown, the event runs from 1:00 p.m. to 5:00 p.m. at AISPP. It brings together students from international schools across Phnom Penh to solve math problems that call for critical thinking and teamwork.

How the Phnom Penh Intermediate Math Competition is organised

AISPP’s competition announcement on LinkedIn describes four rounds of mathematical challenges. Each team has three students, with one student from each of Grades 8, 9 and 10. The school also announced a mixed-school challenge that gives students a chance to solve problems alongside peers from other schools.

A team with students from different grades may draw on different ways of tackling the same problem. One student might spot a pattern by listing examples, while another might draw a diagram or express the pattern as a rule. Explaining why each approach works helps the group agree on a solution and identify any assumptions it still needs to check.

How students can practise working as a team

One way to prepare is to work through a problem with a partner and compare methods before checking the answer. For example, ask how many different rectangles can be made with 36 unit squares. One student might sketch a few arrangements while another lists factor pairs. Then they can decide whether turning a rectangle creates a new arrangement and explain how they know their list is complete.

Teams can also practise what to do when they get stuck. A student can restate the question in their own words, test a smaller example or ask a teammate to explain a different approach. For a short timed practice, teams can set aside the last minute to check that their answer fits the question and that someone can explain the reasoning clearly.

Ways teachers and families can support preparation

Teachers can give mixed-grade groups one problem with several possible approaches and ask each student to explain a step. Rotating who records the work and who presents the solution gives everyone a chance to practise both roles. Afterward, groups can compare where their approaches differed and which method made it easiest to check the answer.

At home, parents can ask a student to explain where they started or how they checked their work. If the student is unsure, asking them to draw the problem or try it with smaller numbers can give them a way back into it. The student can then describe what changed in their thinking and whether the same method works for the original question.

Venue and event enquiries

The AISPP contact page lists the campus at 76 Angkor Boulevard, Sangkat Toul Sangke 2, Khan Russey Keo, Phnom Penh. Families and school coordinators can contact AISPP to confirm arrival instructions, what students should bring and whether spectators can attend. The Facebook countdown gives the venue and hours. AISPP’s LinkedIn announcement invites people seeking further details to message the school.

The Phnom Penh Intermediate Math Competition gives students a chance to compare how they reason through unfamiliar problems with peers from other grades and schools. After the event, a useful classroom follow-up is to have students share one method they learned from a teammate and show how they would use it on a different problem.
