### Lattice MultiplicationA NEW way to Multiply

By: Mrs. Overley

Lattice Multiplication

• Determine the number of digits in the first factor. (The numbers on the Top)

• Then determine the number of digits in the second factor. (The numbers on the Bottom)

• Now construct (draw) a big box and divide it to where you have the same number of squares needed for the number of digits located in the top and bottom factors. See left.

• Now divide each of the smaller boxes in half.

Like below.

• Now, write the first factor across the top and the second factor down the side.

N such as 6, then place a 0 in the top half the box and write a 6 in the bottom half.)

• Now add each of the columns diagonally. Regroup when necessary.

• Follow the same steps for 3-digit by 2-digit numbers! (Or can be used with any multiplication problem!)
