What Is A Bar Model In Math

Bar modeling is a pictorial method used to solve word problems in arithmetic.

What is a bar model in math.

These bar models can come in multiple forms such as a whole part or a comparison model. Bar models help us to attain an understanding of how a problem needs to be solved and calculated. This approach can be used in addition subtraction multiplication division fractions and percents. 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.

With the whole part model students would draw a rectangular bar to represent a whole larger quantity which can be subdivided into two or more parts. Eventually they will no longer need to draw all the boxes. Teachers can model their own word problems based in cognitively guided instruction and singapore math to help build upon each student s natural problem solving strategies. Our bar model tool provides a dynamic platform for creating visual representations of mathematical problems.

Bar models are most often used to solve number problems with the four operations addition and subtraction multiplication and division. How to introduce bar modeling. Bar modelling is an essential maths mastery strategy. Here for instance one rectangle or box of the bar model represents a value of 6.

In this lesson you will learn how to solve a word problem by drawing a bar model. In math a bar model can be defined as a pictorial representation of a number in the form of bars or boxes used to solve number problems. Instead they just draw one long bar and label it with a number.
