Product Description
Bar model is a way to draw problems with visual representation. It helps students to achieve mastery in Maths in all operations: addition, subtraction, multiplication and division. As children move to Upper KS2 it hugely benefits children to solve more complex problems by visualizing them.

The bar modelling is actually taken from Singapore mastery textbook that follows the approach of concrete — pictorial — abstract (CPA). In this approach the children are given the actual objects like cubes, Numicons or other manipulative to start with, then move to draw boxes and finally they don’t need any objects to solve the problem.

Bar modelling helps children to understand math better by visualizing and making sense of the problems, so children can move towards more abstract calculations. This intuitive method makes children more confident in their operations needed to solve problems. The bar model not only helps in addition and subtraction, it applies in almost all areas of math.

It is versatile and simple to use as children don’t need anything to use it except a pencil and paper.
