By the time they reach Year 5, the third year in KS2, children should be familiar with certain properties of numbers which they have come across in their Maths lessons. They should, for example, know the difference between multiples and factors and should also know what square numbers are.

The properties of numbers are things like factors or multiples. Learning the properties of numbers is all about understanding the relationships between them. For example, do you know the multiples and factors of numbers? Let's take the number 8. Its multiples are all of the numbers in the 8 times table from 0 upwards. Its factors are the numbers that can be multiplied together to make 8, which are 1, 2, 4 and 8. How much have you learned about the properties of numbers?
