Mark Valentine, teaching head of Nethermill Primary School near Dumfries, gives a group of four children a challenging problem to solve, involving measurement, geometry and algebra.
The problem requires the children to listen to each other and to work together co-operatively. The two boys and two girls are closely observed as they consider how to tackle the problem, make mistakes, get stuck and arrive at the "eureka" moment.
At the end of the session the children report back to Mark, explaining how they arrived at the solution, an important part of the problem solving process.
