The Mathematics of Counting

Terminology

Counting Sequence

There is an ordered sequence of number names. Counting involves using the same sequence each time, starting with one. Extending the counting sequence is accomplished by repeating certain aspects of the previously used numbers in a structured way (according to our base-ten number system)

One-to-one correspondence

Exactly one number from the counting sequence is assigned to each object in the collection

Cardinality

The last number assigned to an object in counting the collection indicates the total quantity of objects in the collection
