How high can you count?
How about counting to one hundred or one thousand?
Cardinal Numbers
The numbers you use for counting are called "cardinal numbers", for example:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10...
eleven, twelve, thirteen, fourteen, fifteen...
Here are some other "cardinal numbers" you need to remember for counting:
0 | zero |
1 | one |
10 | ten |
100 | one hundred |
1,000 | one thousand |
1,000,000 | one million |
1,000,000,000 | one billion |
Ordinal Numbers
The numbers you use to talk about the order of things are called "ordinal numbers", for example:
My horse came in first.
I was the fifth person in line.
Here are the first ten ordinal numbers:
first | 1st | sixth | 6th |
second | 2nd | seventh | 7th |
third | 3rd | eighth | 8th |
fourth | 4th | ninth | 9th |
fifth | 5th | tenth | 10th |
Multiples
Sometimes numbers aren't expressed in cardinal or ordinal numbers.
Here are a few examples:
half (1/2)
single (1)
double (x2)
triple (x3)
quadruple (x4)
a pair/couple (2)
a few (2 or 3)
several (more than 3 but not many)
a dozen (12)
a half dozen (6)
