In Year 5, which is the third year in KS2 Maths, you'll learn cool things about numbers. Numbers have special friends called factors and multiples. Imagine factors as numbers that can team up to make another number, like 1, 2, 4, and 8 for the number 8! Multiples are like a group of friends in a times table – for 8, it's 0, 8, 16, and so on. Maths is like solving number puzzles! How much do you know about these number pals?
Let's play a fun quiz for 9-10 year olds and test your knowledge of the properties of numbers. See how many number secrets you can remember!
