Problem solving is a major part of the eleven plus and bar modelling technique is a perfect solution to the challenging problems faced by pupils.
The eleven plus has a combination of arithmetic and problem-solving questions which can seem challenging to many pupils. Teachers often find it a challenge to try and stay withing the boundaries of comprehension for certain age groups, yet when they fail to do this they then revert to how they would solve the problem, NOW, with their current experience. In most challenging cases, teachers revert to algebra to solve problems but this is not always the most simple solution especially for children aged 9-11.
