Our intention is to provide the cards as a conversational aid – for the adult to use – appropriate to the child's need.
As soon as the child's visual facility and mental development can appreciate the value of printed matter: use a card!
Follow the child's numerical development from learning the shapes of numbers through to writing – and spelling – words. There are cards for oddities such as 'pair', '5th'.
The cards only cover the digits (0,1,2,3,4,5,6,7,8,9), and it is intended that they are used singly, as digits. The intent is to consolidate the range of uses of the digits such that when the hurdle of place value is reached it will not be too much of a hurdle to leap over.
