The bar model represents the 6 meals and is labelled to show the total cost. The unknown amount is the cost of each meal and is labelled on the bar model. To solve the problem, £138 needs to be ...
Similarly, we can use a comparison bar model, as we are seeking to find the difference between the total amount of eight apples and Ahmed’s five apples. (Shown on the right-hand side of the slide.) Either way, an adult modelling or children solving the word problem using either type of bar model should arrive at the correct answer.
The bar model method is a great way to visualise tricky mathematical concepts and solve problems. They are a quick and easy way to represent a situation in a word problem. Bar modelling can be ...
Bar models are visual strategies used in a mastery approach to support children in accessing a maths problem. They use different-sized rectangles to represent numbers and the rectangles, known as bars, are proportional to the number. A large number is represented by a large bar, whereas a small number is represented by a small bar.
Aug 6, 2024 · In maths a bar model is a pictorial representation of a problem or concept where bars or boxes are used to represent the known and unknown quantities. Bar models are most often used to solve number problems with the four operations – addition and subtraction, multiplication and division. In word problems, bar models help children decide which ...
Mar 20, 2017 · Start bar modelling early. Bar models can be used very successfully at KS1. Start with part-whole bar models using pictures and move to discrete bar models where each square represents one. As the years go by, move children on to continuous part-whole bar models and comparison models, with a view to eventually removing the need for bar models ...

The bar model is used in teaching for mastery to help children to 'see' mathematical structure. It is not a method for solving problems, but a way of revealing the mathematical structure within a problem and gaining insight and clarity to help solve it. It supports the transformation of real-life problems into a mathematical form and can bridge ...
