Recognise square and cube numbers KS2 Revision
What you need to know
Things to remember:
- Because you should know your times tables up to 12×12, you should know all the square numbers up to 12^2
- You need to learn the cube numbers up to 5^3
A square has side lengths of 5cm.
How do we find the area of a square? We multiply the sides together!
Area = 25cm^2
And this is exactly how we make squares numbers; we multiply a number by itself! Because we should know our times tables up to 12×12, we should be able to learn our squared numbers up to 12×12.
Cubed numbers are only a little trickier, we just multiply a number by itself twice.
Question 1: What is 7^2?
Question 2: What is 4^3?
