Short multiplication is another way of representing 2-digit by 1-digit multiplication.
There are similarities between the representations of multiplication.
Arranging the factors in columns allows you to organise the partial products into a column addition.

When using the short method, pupils may not align the digits correctly with the same place value.

Continue to ask what each digit that has been recorded represents, linking back to the place value chart.

Short multiplication - A way of recording using columns to set out and calculate a multiplication.
Factor - A number that divides exactly into another number.
