So, what is an inquiry-based maths classroom? An inquiry-based maths classroom is a student-centred teaching model that emphasises learning through hands-on activities and problem-solving. In this type of classroom, students are not merely passive recipients of knowledge; instead, they actively engage in the learning process by asking questions, participating in discussions, conducting experiments, and summarising their findings. The teachers act as facilitators, encouraging students to explore, discover, and share their insights. This approach not only helps students build a solid mathematical foundation but also cultivates their critical thinking and problem-solving skills.

Additionally, in the activity of exploring the place value chart, children further investigate mathematical patterns by arranging small discs on the place value chart. Through collaboration with their peers, they unveil the secrets of placing an equal number of discs on the place value chart: the sum of the digits in the ones and tens places equals the number of discs; the quantity of numbers formed is always one more than the number of discs; and when arranging the numbers in ascending order, the latter number is always nine more than the previous one. This series of inquiry activities not only develops their logical thinking skills but also enhances their teamwork spirit.
