Bar modelling

The bar model is used in Singapore and other countries, such as Japan and the USA, to support children in problem solving. It supports problem solving by revealing the mathematical structure within a problem and gaining insight and clarity as to how to solve it. It supports the transformation of real life problems into a mathematical form and can bridge the gap between concrete mathematical experiences and abstract representations. It can be used to represent problems involving the four operations, ratio and proportion. It is also useful for representing unknowns in a problem.
