Evaluating Methods, Improving Solutions

Evaluating Methods, Improving Solutions

When solving problems, it's important to recognise that the process doesn't end when the problem is solved. To help our students become resilient problem solvers, we need to offer opportunities to evaluate different solution methods and reflect on their own and other people's solutions. 

In this collection of problems, we have included tasks that can be solved in more than one way, and tasks that give students space to solve, reflect and revisit.
