Have you taught your students to multiply with **lattice multiplication**? If not, they're missing out on a visual approach that most students seem to get and enjoy! Here's a couple of examples to see *how it works*.

**Let's Multiply 38 X 42 the Lattice Way**

- Draw a 2-row 2-column box grid as shown in picture below. grid
- Write the
*first number across the top*and the*second number down the right side of the grid*as shown.

- Now draw diagonal lines on each of the small squares as seen in the picture below.

- Now here comes the multiplication part.
- Multiply the
**first digit**of number across the top by the**first digit**of the number down the side of grid. So for our example, we multiply the**3 times 4**and get 12. - Place the result in the box as pictured.

- Next multiply the
**second digit of the number across the top**of the grid by the same**first digit**of the number on the right side of the grid. - Place the result in the boxes as shown.

- Now multiply the
**first digit of number across the top**by theof the number down the side of grid.*Second*digit - Place the results in the boxes as pictured below.

- Now multiply the
**second digit of number across the top**by theof the number down the side of grid.*Second*digit - And now write your result in the boxes. You can see our example below.

- Now
**add diagonally**along the yellow arrows.

- To get the
*answer*, read or write the numbers down the left side and then across the bottom.

*How about that! Pretty Cool, huh!* Why don't you give it a try and see how you like it. Now how about trying it out with your own set of two digit numbers.
