Single Idea 17451

[filed under theme 6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / e. Counting by correlation ]

Full Idea

'Just as many' is independent of the ability to count, and we shouldn't characterise equinumerosity through counting. It is also independent of the concept of number. Enough cookies to go round doesn't need how many cookies.

Gist of Idea

We can know 'just as many' without the concepts of equinumerosity or numbers

A Reaction

[compressed] He talks of children having an 'operational' ability which is independent of these more sophisticated concepts. Interesting. You see how early man could relate 'how many' prior to the development of numbers.
