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to keep our content available through a partnership with another educational provider, but this provider has since withdrawn from the agreement.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 are cube numbers?
What are cube numbers?
A cube number is a number that is the product of three numbers which are the same. In other words, if you multiply a number by itself and then by itself again, the result is a cube number.
This diagram makes this concept clearer:
Cube numbers can be represented visually as 3D cubes of single, unit cubes. To write the mathematical formula for cube numbers we add a small 3 next to and above the number, for example: 23.
Cube numbers in primary school
Children start to learn about square numbers in Year 5. This learning is then consolidated in Year 6, when children are expected to know the notation for both square numbers (²) and cube numbers (³).
They may be given the above diagram and asked to work out what the next three cube numbers are. In this case, they would be expected to realise that the next cube number is the result of 5 x 5 x 5, which is 125. The one after that would be 6 x 6 x 6 = 216.
Often in 11+ tests and secondary entrance exams, children are given a sequence of numbers like those above, and required to work out what the pattern is and how to continue it.
