Using maths modelling to stop pet abandonment

The Australian judging panel awarded Northern Beaches Secondary College Manly Campus and Brisbane Boys’ College the Outstanding Achievement award, and both teams will advance to the international judging round for 2024. The international results will be announced in late June. 

Coordinated by the Australian Council for Educational Research (ACER) in Australia, the IM2C asks students to use their research and mathematical and creative abilities to develop a mathematical model to address a real-world problem. 

This year’s challenge was about pet ownership and the problem of abandonment. Teams were asked to define the concept of a ‘pet’, and build mathematical models to determine which households would be prepared to own a pet and forecast future pet ownership. 

Dr Kristy Osborne, ACER Senior Research Fellow and IM2C Australia Director, praised the Australian teams.

“It's impressive to see how the students tackled a contemporary social issue, with pets being abandoned in record numbers in many countries, and also to see how the IM2C empowers young people to work as problem-solvers,” she said.  

Teams had to summarise the 3 components of the challenge, write a letter to a fictitious animal welfare society, and develop and communicate their mathematical model within 20 pages. Teams were also asked to report on any questions asked of artificial intelligence (AI) and AI-generated responses. This was the first year teams were permitted to use AI. 

In another first for IM2C 2024, the winning teams from each state and territory can visit local university mathematical modelling research groups and spend ‘a day in the life’ of a tertiary modelling researcher, learning about how modelling is used to solve real-world problems.  

The judges identified 13 finalists from the 73 teams who participated from 21 schools. Special mention was awarded to Whitsunday Anglican School as the top entrant of the years 7 to 9 teams.
