There are several useful methods for multiplying.
This one is one of the most space-consuming, but is also one of the easiest, as it only requires you to know your tables up to 9x9. This makes it especially useful for KS2 or less-able KS3 students (age 9+)

Signing UpStep 1: The grid method.
The method has several names, but is most often called the grid method.
To multiply two numbers together, the numbers are first broken down into their component place-value chunks.
For instance, let us multiply 47 by 68.
"47" is actually "40 + 7" and "68" is "60 + 8".
These numbers are written into a grid, as in the illustration below:
