Eventually they will no longer need to draw all the boxes.
What is a bar model in math.
This approach can be used in addition subtraction multiplication division fractions and percents.

In this lesson you will learn how to solve a word problem by drawing a bar model.
Bar models are most often used to solve number problems with the four operations addition and subtraction multiplication and division.
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.
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.
Instead they just draw one long bar and label it with a number.
