**Cardinal and Ordinal Adjectives**

** Cardinal: **these types of numbers answer the question, “how many?”

**The first cardinal number is zero (0). Every time (0) is used, it requires a plural noun.**

Example:

How many birds are in the backyard?

There are zero birds.

There are no birds.

*remember*

Saying there are “no” birds is the same as saying there are “zero” birds.

If you want to say there is one (1), this requires a singular noun.

Example:

How many balls are on the court?

There is one ball.

One = Cardinal number adjective

Ball = singular noun – representing one (1)

Every other number (2 -> infinity) requires a plural noun.

How many guitars do you have?

I have three guitars.

Three = cardinal number adjective

Guitars = plural noun representing three (3)

How many baseball cards do you have?

I have 825 baseball cards.

825 = cardinal adjective

Baseball cards = plural noun representing 825
