TheSchoolRun.com closure date
As we informed you a few months ago, TheSchoolRun has had to make the difficult decision to close due to financial pressures and the company has now ceased trading. We had hoped to keep our content available through a partnership with another educational provider, but this provider has since withdrawn from the agreement.
As a result, we now have to permanently close TheSchoolRun.com. However, to give subscribers time to download any content they’d like to keep, we will keep the website open until 31st July 2025. After this date, the site will be taken down and there will be no further access to any resources. We strongly encourage you to download and save any resources you think you may want to use in the future.
In particular, we suggest downloading:
- Learning packs
- All the worksheets from the 11+ programme, if you are following this with your child
- Complete Learning Journey programmes (the packs below include all 40 worksheets for each programme)
You should already have received 16 primary school eBooks (worth £108.84) to download and keep. If you haven’t received these, please contact us at [email protected] before 31st July 2025, and we will send them to you.
We are very sorry that there is no way to continue offering access to resources and sincerely apologise for the inconvenience caused.
What is chunking?

What is chunking?
Chunking is a method used for dividing larger numbers that cannot be divided mentally.
Chunking is repeated subtraction of the divisor and multiples of the divisor – in other words, working out how many groups of a number fit into another number.
The purpose of chunking is for children to be able to think about the relationship between multiplication and division. It involves using rough estimates of how many times a number will go into another number and then adjusting until the right answer is found. Once these skills have been practised, teachers will often encourage children to move onto the quicker 'bus stop' division method.
Here is an example of how you could divide 12 by 3 using chunking:
Chunking with remainders is the next stage in children's understanding:
Finally children begin to use division notation, writing down their chunking calculation in this format:
Chunking can be helpful with problem-solving where the answer has a remainder, for example:
167 people are going on a trip. They are going to travel on coaches that each hold 45 people. How many coaches will be needed?
You could work this out doing the following:
- I thought about how many times 45 would go into 167 and thought it might go in 4 times.
- When I multiplied 45 by 4 it made 180, which was too big.
- I then worked out 45 x 3 which equals 135.
- I had to take 135 away from 167 which left 32.
- 32 doesn't equal another 'set' of 45, so the answer was 3 remainder 32.
- I then looked at the problem again and worked out that they would need 3 coaches which would each contain 45 people, then they would need another coach for the remaining 32 people.
As part of the new national curriculum introduced in September 2014 teachers have re-introduced the long division method as the recommended way to divide large numbers, so children will probably move on from chunking to use long division in Years 5 and 6.
