Notice how in Spanish the ordinal number must agree in gender and number with the noun it is referring to. 

Very often ordinal numbers are accompanied by determiners such as articles (el, la, los...) or possessives (mi, nuestro...). Bear in mind that these must agree with the number and noun as well, e.g "la primera planta", "nuestro segundo nieto", etc.

 

First and third before masculine singular nouns

Note that primero (first) and tercero (third) have a shorter form when they are placed in front of a masculine singular noun.

Carlos no es mi primer marido. Carlos is not my first husband.

Este es su tercer año en la universidad.This is his third year at the university.

Cardinal numbers = 1, 2, 3, etc.

Ordinal numbers = describe an order/rank = 1st, 2nd, 3rd, etc.

Fractions = describe a part of a whole = half, third, fourth, etc.
