The lesson features a video about using an area model to help solve a problem.
How do you do a division area model. In the first box you would put 4 and put a 2 on the quotient part. Then add to get the area of the whole. Find the areas of the pieces individually.
In the area model for division the components of division divisor dividend and quotient are displayed with a rectanglethe rectangle makes the connection between area length x width and division. For example you can find the product 23 37 by finding the area of a rectangle with a width of 23 and a length of 37. Then you have 1 left which needs to be divided into 2 equal parts.
Students will be asked to divide a 3-digit number by a 1-digit number using area model division. Say you are dividing 5 by 2. In other words when we consider the product 32 23 geometrically it can be interpreted as the area of a rectangle of the length of 32 units and width 23 units.
It is a mental math based approach that will enhance number sense understanding. With this division strategy students divide by breaking the dividend into its expanded form. In this 1 Digit Divisors set students divide whole numbers in the hundreds and thousands by a 1 digit divisor division with 3 digit dividend.
PDF 576 MB These Area Model for Division Task Cards were designed to scaffold students learning and understanding of dividing whole numbers with the areaarray model. Repeat the process until you get a 0. Students will be able to use the area model to solve division problems with single digit and two-digit divisors.
The area of a shape is the space occupied by the shape. Then students use familiar multiplication facts to divide. Students solve a word problem by completing an area model and division problem.
In this video Mrs. She scaffolds this approach by decompo. So lets quickly define these two methods.
In the second approach students can begin with any number that makes sense to them and they are not required to always take the largest amount possible from the dividend. Lauren Flynn models how to divide a three-digit number by a 2-digit divisor using the area model. If a rectangle has a length equal to 32 units and a width of 23 units then we can calculate this area by taking the product 32 23.
What is Area Model Division. Area Models Worksheets Without Remainder. Figure out the quotient by dividing the given 3-digit numbers inside the rectangle by the single-digit divisors.
This method is also known as the rectangular array model the box method and the. The Box Method also referred to as the Area Model is one of these strategies. Students solve the equation by subtracting multiples until they get down to 0 or as close to 0 as possible.
Ive found that the area model for division is usually taught one of two waysin one approach students are taught that they MUST use the largest partial quotient for each place of the dividend.

You have a total of 5 for the dividend inside the area model and 25 for the total quotient.
What makes the area model useful is that area is a conserved quantity. They also practice isolating the variable in algebraic equations involving. Of course there is little gained if you simply multiply 23 37.
Visually represent the division equation as a rectangle with these level 1 area models. In other words you can break one large area in this case that of a 23 37 rectangle into several pieces. The math video and worksheet included in this resource were created to help students learn practice and apply area model division concepts for fourth grade.
