One-to-one correspondence is a basic mathematical skill and without it children are unable to count accurately. To be able to say one number to one object seems very simple, but anyone who has ever watched a child who is in the very beginning stages of counting will have seen them saying numbers out loud while pointing or touching objects, without those numbers actually matching up with the objects being counted!
Another simple developmental counting error you will see is a child who counts the same object more than once or skips objects entirely. Presenting activities that allow opportunity in a self-correcting way to practise this one-on-one correspondence helps put in place the experience necessary for successful counting.
They are self-correcting in that there should be only one object in each compartment and running out or having some left over allows the child to see that an error has been made. These activities can be presented to children anywhere from around 18 months and upwards, depending on the developmental level of the child.
