Flexible approaches to problem solving
Being able to solve problems flexibly is a key ingredient of what it means to be a good mathematician. The problems in this feature are designed to offer alternative ways of thinking about situations so that students can explore different ways of arriving at a solution.
The last day for sending in solutions to our live problems is Monday 12 October 2020.
