Session 4, Part B:
Area Models for Multiplication and Division

In This Part: Multiplication with Manipulatives | Multiplication Model
Division with Manipulatives | Division Model

You can also use the area model for multi-digit division. Let's do some multi-digit division problems; for example, 18711.

This activity requires the Flash plug-in, which you can download for free from Macromedia's Web site. For a non-interactive version of this activity, use manipulatives, or print and cut several copies of the shapes from a PDF file.

Problem B4

Solution  

a. 

Using one flat, eight longs, and seven units to represent 187, construct an area model that would indicate the solution to 18711.

Stop!  Do the above problem before you proceed.  Use the tip text to help you solve the problem if you get stuck.
As you construct the area model, think about division as the inverse of multiplication.   Close Tip

 

b. 

How can you represent this model using mathematical computations?


 

Problem B5

Solution  

Construct an area model that would indicate the solution to 18213.


Stop!  Do the above problem before you proceed.  Use the tip text to help you solve the problem if you get stuck.
For this problem, remember that you can break apart one of the longs into 10 units.   Close Tip
