1 Area Model for Multiplication

2 43 x 27 = ? Break apart the numbers by place values Draw a rectangle and label the dimensions Multiply Then add the parts 20 7 40 3 40 x 20 = 800 3 x 20 = 60 40 x 7 = 280 3 x 7 = 21 800 280 60 + 21 1,161

3 Try Another One: 34 x 45 Break apart the numbers by place values Draw a rectangle and label the dimensions Multiply Then add the parts 40 5 30 4 30 x 40 = 1200 4 x 40 = 160 30 x 5 = 150 4 x 5 = 20 1200 150 160 + 20 1,530

4 Do this one on your own: 26 x 78 Break apart the numbers by place values Draw a rectangle and label the dimensions Multiply Then add the parts 70 8 20 6 20 x 70 = 1400 6 x 70 = 420 20 x 8 = 160 6 x 8 = 48 1400 420 160 + 48 2,028 How did you do?

5 This method of multiplying supports students who are visual learners because they can easily see the parts. This method also supports students geometric knowledge of area.
