Long multiplication or column multiplication is a written method of multiplying numbers usually a two- or three-digit number by another large number. It is usually used in Year 5 and Year 6 once children have got the hang of using the grid method. The benefit of the grid method is that it encourages children to think about place value and multiply multiples of ten and one hundred. Once they have got the hang of this, long multiplication is a faster, more efficient technique to use. As in column addition and column subtraction , the numbers are positioned in a column as follows:. Here is an example of an array to demonstrate 5 x 3 or 3 x As you can see from the above objectives, children do not need to multiply two-digit numbers by three-digit numbers until Year 6, so the long multiplication method would probably not be taught until then although able Year 5 children may use it as well.

Before you learn the standard algorithm for multiplication, you typically understand multiplying multi-digit numbers in parts and adding the partial products at the end. In the standard algorithm, it is more of a shorthand way of multiplying in parts, while doing some of the addition at the same time as multiplication. It is often referred to as multi-digit multiplication and is the recommended method to use when multiplying larger numbers. Before tackling the standard algorithm, students should ideally be confident with their multiplication facts and understand key terms like the multiplicand and the multiplier.
