Children in Year 5 should already be aware of the effect of multiplying a number by 10 or 100. They should also be aware that multiplication and division are inverse operations. So, if they know that multiplying a number by 10 moves each digit one place to the left, then dividing by 10 will move each digit one place to the right.

Place value charts are a great way to show this and can be used to demonstrate dividing by 100 and 1,000. The pages we have just published use place value charts and keep to numbers that avoid decimals. They are a great way to show what is happening when we divide by 10, 100 or 1,000.
