Bar Model Math 1st Grade
In math a bar model, also known as a strip diagram, 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. Write and solve multiplication equations using a bar modelIn this lesson you will learn how to write and solve a multiplication equation by using a bar model. Bar Models can be used to solve different kinds of multiplication and division word problems. In Grade 2 and early in Grade 3, students learned to use bar models to solve two-step problems involving addition and subtraction. This is extended in this chapter to include multiplication and division.
