Expanded multiplication of a 3-digit by a 1-digit number will give three numbers to add to calculate the overall product
Short multiplication builds the overall product from the ones column to the hundreds with no regrouping.
The partial products can be seen in the expanded and short multiplication strategies.

Misalignment of digits when setting out short multiplication.

Clear teacher modelling, ask pupils 'what does this digit represent?' Return to expanded layout briefly, before re-doing the problem.

Expanded multiplication - A way of recording the steps of a calculation focusing on partitioning one or more factors and showing partial products.
Short multiplication - A way of recording using columns to set out and calculate a multiplication.
Factors - Numbers we can multiply together to get another number.
