Maths is the system we share to help us organise our understanding of the world.

Try to help your child to learn to use number reliably through their play.

Concentrate on these few key principles:

  1. The one to one correspondence principle where you give only one number name to each object you are counting.
  2. The stable order principle where you know that numbers need to be said in the same order each time you count.
  3. The cardinal principle where you understand that the last number counted tells you how many things there are altogether.
  4. The abstraction principle where you realise that non-physical as well as physical things can be counted.
  5. The order-irrelevance principle where you know that it doesn’t matter which order you count in or where you start as long as every item in the collection is only counted once.
