Mathematical investigations offer a dynamic and engaging way to introduce students of all ages to the wonder, creativity, and real-world relevance of mathematics. These explorations encourage curiosity, develop problem-solving skills, and help learners see the value of mathematics beyond the classroom. Whether working individually or collaboratively, students are given opportunities to showcase their talents, tackle meaningful challenges, and develop deeper mathematical understanding.
For primary students, investigations also provide a valuable introduction to mathematical thinking and structured inquiry, laying a strong foundation as they prepare for the transition to secondary school. They learn not only how to approach problems thoughtfully but also how to communicate their reasoning clearly and effectively.
Participating in a mathematical investigation competition can be especially rewarding. A successful submission can earn students well-deserved recognition, enhance their school’s reputation, and even bring in cash prizes. More importantly, it can inspire a lifelong appreciation for the power of mathematics.

Information on Undertaking the Competition
Â
A video conference was held in March 2025 with teachers, parents, and guardians of primary-level students interested in supporting their children’s participation in the 2025 South Australian Investigating with Mathematics Competition. The meeting was guided by an accompanying PowerPoint presentation, which outlined key discussion points and provided a clear overview of the competition process. It also offered practical tips and suggestions to help ensure the success of the students’ investigations.

Guidelines for Completing the Investigation: This A3 poster puts the four key steps in developing and then seeing through an investigation:
- See
- Plan
- Do
- Check
Guidelines for Presenting the Investigation: This A3 poster sets out the nine recommended steps to lead the entrant to present a well constructed investigation.
100 Inspirational Titles is a list of possibilities that can spark each entrant’s imagination in their pursuit of an investigation.
The marking rubric will provide teachers and guardians of Primary School level competitors with an understanding of how the entrants’ markers will be assessing the submissions. Two rubrics are provided; (1.) Years 3 to 12, and (2.) Reception to Year 2.Â
Examples from 2024
Year 3 Investigation
The class agreed to focus on helping our reception and year 1 students as they were the newest to the school. The class wanted to assist them in having positive playtime experiences.
But how would the class do this?
Year 4 Investigation
The aim of the investigation was to use a variety of different things to measure a year. There are lots of ways to measure a year – and there might be a right and a wrong way to measure a year, but;
- some ways might be more (or less!) fun,
- some ways might be easier and some ways harder,
- some ways might help me make better decisions, and
- some ways I might need help with.
Year 5 Investigation
Have you ever wondered how to choose the best pizza?
This investigation selected and then compared different types of Hawaiian pizzas using mathematics in order to find out which was the best overall.

Sponsor of Primary Competition : Kumon
The S.A. Investigating with Mathematics Competition’s primary school section is proudly supported by Kumon.
Kumon Mathematics is an after-school learning program focused on developing strong calculation skills and enabling students to advance to high school mathematics through self-learning, with the goal of encouraging independent learners.
The Kumon Method was developed by Toru Kumon, a Japanese high school mathematics teacher, who helped his son by creating worksheets to improve his calculation skills.
The Kumon program emphasises independent learning, with students working through worksheets at their own pace, supported by instructors who provide guidance and encouragement.
The Kumon Mathematics program aims to develop quick and precise calculation skills, which are crucial for success in higher-level mathematics courses.
