Children in Year Two use both grouping and sharing to divide groups of objects. They also begin to understand how multiplication and division are the inverse of each other by finding families of facts.
In Year Three, children divide 2-digit numbers by 1-digit by partitioning them into its tens and ones then dividing each by the divisor (no regrouping). This then moves on to dividing with regrouping, this time partitioning the 2-digit numbers in to the divisor multiplied by 10 and the other part. Doing this prepares children for the formal bus stop method, which they use alongside the part part whole model.
In Year Four, children divide by 1 to learn that the answer is always the dividend. They find related facts to also see that when you divide the dividend by itself, the answer is always 1. Remainders are also introduced, with children returning to grouping to put objects into groups of the divisor and seeing how many objects are left.
Children in Year Five learn how to divide by 10, 100 and 1000. They also divide 4-digit numbers by 1-digit using the expanded bus stop method that they first began using in Year Three.
In Year Six, children learn how to use long division to divide by 2-digit numbers, building on the method taught in Year Five.
