1 The Area Model of Multiplication Using Base Ten Pieces And Boxes To Build Understanding of Multiplication

2 Use the Place Value Addition to Rename =

3 We can solve two easier problems, then add the sums. Remember 32 =

4 Suggestion: Let students use a calculator to discover numerical patterns. Do they know what happens when you multiply by a multiple of 10? 3 x 4 = x 4 = 120

5 Lets Model It 32 x 4

6 Lets Solve Those Two Problems 30 x 4 = x 4 = 8

7 30 x 4 = x 4 = = 128 Add the two sums.

8 2 x 4 = 8 30 x 4 = 120

9 Lets Model It With Boxes Instead of Base Ten Pieces 30 x 4 = 120 8

10 Students Can Draw Their Own Boxes They dont have to be concerned with the size once they understand the concept Student should compare the two area models and the traditional algorithm.
