The Area Modelof Multiplication

Using Base Ten Pieces And Boxes

To Build Understanding of Multiplication

Use the Place Value Addition to Rename

32

32 = 30 + 2

We can solve two easierproblems,

then add the sums.

Remember

32 = 30 + 2

Suggestion: Let students use a calculator to discover numerical patterns.

Do they know what happens when youmultiply by a multiple of 10?

3 x 4 = 1230 x 4 = 120

Let’s Model It

32 x 4

Let’s Solve Those

Two Problems

30 x 4 = 120

2 x 4 = 8

30 x 4 = 120

2 x 4 = 8

120 + 8 = 128Add the two sums.

2 x 4 = 8

30 x 4 = 120

Let’s Model It

With BoxesInstead of Base Ten Pieces

30 x 4 = 120

8

Students Can Draw

Their Own BoxesThey don’t have to be concerned

with the size once they understand the concept.
