Sounds simple! However, it takes pretty much all children a huge amount of time to get really secure with this skill. For example, if you are counting objects, you point at the first item and say ‘1’, then point to the second and say ‘2’ and so on.

However, it is a simple skill to understand and get your head around, and a fun one to teach too. There is a lot of jargon around the teaching of maths, and terms like ‘1 to 1 correspondence’ can seem quite intimidating. This article is just as much for parents as teachers. Without 1 to 1 correspondence, all these are a non-starter. 1 to 1 correspondence is super important! In the ten years I have taught young children between the ages of 3 and 5, I have found that 1:1 correspondence is a foundation for all the skills that come after it: adding, subtracting, finding one more and less, and lots of other things too.
