There are a number of methods for multiplying two numbers together.

One that is very popular (even if it's a bit slower than other methods) is the grid method.

e.g. Calculate 36 x 25.

Step 1: Split the numbers up.  ->  36 = 30 + 6 and 25 = 20 + 5

Step 2: Create a grid and put the numbers around the outside.

 30 6 20 5

Step 3: For each of the spaces in the grid, multiply the number on the top by the number on the left side.

 30 6 20 600 120 5 150 30

Step 4: Add all these numbers together.

 600 +   120 +   150 +     30 900

Before you start this activity, make sure you have a pen and paper handy so that you can create your own grids as we go.
