## Cardinal Numbers

The numbers you use for counting are called "cardinal numbers", for example:

eleven, twelve, thirteen, fourteen, fifteen...

Here are some other cardinal numbers you need to remember for counting:

## Ordinal Numbers

The numbers you use to talk about the order of things are called "ordinal numbers", for example:
