ORDINAL NUMBERS

Now that you have learned about cardinal numbers, it is time for some ordinal numbers! Ordinal numbers tell you the position of something in a sequence.

Now you can turn any cardinal number into an ordinal number by following these rules:

• Any number that ends in the digit 1 will get the “st” ending.

• Any number that ends in the digit 2 will get the “nd” ending.

• Any number that ends in the digit 3 will get the “rd” ending.

• Any number that ends in the digit 4 will get the “th” ending.

For example:

101st = one hundred and first

42nd = forty-second

33rd = thirty-third

74th = seventy-fourth

The only exceptions involve the numbers “11,” “12,” and “13.” These ordinal numbers are denoted with “th.”

11th = eleventh

12th = twelfth

13th = thirteenth
