In many mid-senior secondary (i.e. Year 10 – 12) classrooms, while teachers understand underlining concepts and connection amongst these concepts are important, the practical teaching might be heavily ‘procedure’ orientated due to the pressure brought by tight curriculum timeframe and high-stake exams. Therefore more pedagogical support is needed so teachers can possibly teach beyond ‘procedure’ in everyday practice. ‘MathTask’ provides a range of mathematical problems, and many of them are exam-style questions, which can elicit deep discussions around a particular topic in mathematics curriculum. In this presentation, I will showcase how some of ‘MathTask’ problems can be utilised in everyday mid-senior secondary classrooms. My intention is to show how teachers can use 'MathTask' style problems as a pedagogical tool to enhance students’ conceptual knowledge and its connection, so as to stretch their adaptivity to solve complex problems, which is also a necessary capacity to achieve well in high-stake exams.
