What Is A Bar Model In Math

In this lesson you will learn how to solve a word problem by drawing a bar model.

What is a bar model in math.

The bar model method is pictorial and develops from children handling actual objects to drawing pictures and then drawing boxes each of which represents an individual unit to represent objects. Bar modeling is a pictorial method used to solve word problems in arithmetic. This approach can be used in addition subtraction multiplication division fractions and percents. Bar modelling is an essential maths mastery strategy.

Eventually they will no longer need to draw all the boxes. How to introduce bar modeling. 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. Bar models are most often used to solve number problems with the four operations addition and subtraction multiplication and division.

Bar modeling is a visual representation strategy that was developed to help students make sense of and solve word problems. 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. Here for instance one rectangle or box of the bar model represents a value of 6. These bar models can come in multiple forms such as a whole part or a comparison model.

Our bar model tool provides a dynamic platform for creating visual representations of mathematical problems. 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. Instead they just draw one long bar and label it with a number.
