Challenging problems provide students with the opportunity for productive struggle, and teachers with the opportunity for differentiated instruction using enabling and extending prompts. In this workshop, you will explore and apply Polya's four principles of problem-solving: understand the problem, devise a plan, carry out the plan, look back (and reflect) to a collection of interesting and challenging problems suitable for Levels 3 - 6. This will include discussion of approaches and strategies aimed at enhancing student success in mathematical problem-solving, such as: * classroom organisation * probing questions to check for understanding and to support differentiation * developing and using numberless word problems This will be a practical, hands-on workshop, where you’ll have the opportunity to experience and apply the approaches discussed.
