Ordinal Numbers

NUMBERS AND OPERATIONS

FIFTH GRADE

An ordinal number is one that indicates the position or order that an element occupies in a set.

The cardinal numbers (1, 2, 3) are used to quantify the size of a set (either finite or infinite), while the ordinal numbers (1st, 2nd, 3rd) are used to describe the position of an element in a sequence (finite or infinite).

We provide you the explanation so that you can easily learn what ordinal numbers from 1th to 1,000th are, how they differ from cardinal numbers and how to read and write them correctly from the first to the thousandth.

HOW TO READ AND WRITE AN ORDINAL THREE-FIGURE NUMBER?

To correctly read and write any three-digit ordinal number we simply have to decompose said number attending to the positional value of each of its figures reading, initially, hundreds, then tens and ones:

738th = 700th (seven hundredth) + 30th (thirtieth) + 8th (eighth)
