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 32 32 = 30 + 2
3
We can solve two easier problems, then add the sums. Remember 32 = 30 + 2
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 = 12 30 x 4 = 120
5
Lets Model It 32 x 4
6
Lets Solve Those Two Problems 30 x 4 = 120 2 x 4 = 8
7
30 x 4 = 120 2 x 4 = 8 120 + 8 = 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. 120 30 8 2 4 Student should compare the two area models and the traditional algorithm.
