What does an area model look like for division?

In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the factors or the quotient and divisor define the length and width of the rectangle. Then we add to get the area of the whole, which is the product or quotient.

What is a division model?

In the array division model, you divide to find the number of counters in each group. The same three numbers are used. The model shows that division “undoes” multiplication and multiplication “undoes” division. So when multiplying or dividing, students can use a fact from the inverse operation.

What is a division number model?

What is a mathematical model for division?

The two main models for division in elementary school mathematics are the partitive (aka, fair-share) model and the quotitive (measurement) model.

What is a division area model?

The area model is also known as the box model. The area model of solving multiplication and division problems is derived from the concept of finding the area of a rectangle. Area of a rectangle = Length × Width.

What is area model 4th grade math?

In 4th and 5th grade, students are introduced to the multiplication of multi-digit numbers. One of the more effective means of finding these products involves an area model, which connects to the 3rd grade result that the area of a rectangle is the product of its width and length.

In the division model you divide to find the number of counters in each group. The same three numbers are used. The model shows that division “undoes” multiplication and multiplication “undoes” division. So when multiplying or dividing, students can use a fact from the inverse operation.
