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.

Problem B4

 a. Using one flat, eight longs, and seven units to represent 187, construct an area model that would indicate the solution to 18711.
 As you construct the area model, think about division as the inverse of multiplication.   Close Tip As you construct the area model, think about division as the inverse of multiplication.

 b. How can you represent this model using mathematical computations?

 Problem B5 Construct an area model that would indicate the solution to 18213.

 For this problem, remember that you can break apart one of the longs into 10 units.   Close Tip For this problem, remember that you can break apart one of the longs into 10 units.
