Dividing by one might seem a bit obvious to us, but it is not always the case for children who don’t yet have a good understanding of division.

Dividing by 1 can be explained in two ways:

sharing equally – the sweets are shared equally between 1 person, in other words the lucky person gets the whole lot!

grouping – there are 6 sweets to be put into 1 group.

Sometimes even adults become confused with dividing by one, and the more complex idea of dividing by zero (how many zeros are there in 10 whole ones????)!

This is probably most suited to Year 3 children.

Divide by 1

Children generally find division harder than multiplication. This is often because the process involves multiplying to find the answer, especially with pencil and paper methods. This page, however,  is aimed at rapid answering using mental methods.

Dividing by ten is the inverse of multiplying by ten. To multiply by 10 move each digit one place to the left. To divide by ten move each digit one place to the right.

Because all the numbers are multiples of 10 there is no need to introduce the decimal point at this stage.

To divide by 100 move two places to the right.

The later questions have different parts of the number sentence to complete: multiplying is the easiest way to do these.

Divide by 10 and 100 (1)

This maths worksheet contains a straightforward set of questions on dividing 2-digit numbers by ten, with remainders. It is aimed at children in Year 2 who are just getting to grips with division and know their ten times table.

The best way to do these is to go through the ten times table until the nearest whole ten below the number is found, then add on to reach the remainder. When dividing by ten the remainder can never be greater than ten.

Further division worksheets can be found both in the Four Rules section under Division or in the separate year groups under Calculating.

Divide by 10 with remainders

This is a follow up page to the earlier solving division problems in your head worksheet. This has a range of different ways of asking division questions which children need to be able to recognise and there are a range of methods that can be used to work out the answers mentally.

It is important the tables are known so that the facts can be used. For example if it is known that 6 x 6 = 36, then 6 x 60 can be quickly worked out as 360, and in turn 360 divided by 6 is 60.

Another useful tip is when dividing by 5 mentally it is often possible to divide by 10 and then double the answer.
