When to use ordinal numbers
Let's review numbers. I know, number are probably the first thing you learned and you might be a total pro at using them, but do you know when to use our cardinal numbers and are ordinal numbers? Did you know that we have two number systems? Let's take a look at these two:
These tell 'how many' of something. What is the quantity?
I ate 2 apples today.
There are 3 people in our group.
These numbers tell us the order of something. The rank or position of something. These numbers use a suffix and they are: -nd, -rd, -st, or -th.
Johnny won 1st place! (first)
Today is June 23rd. (twenty third)
For an easy way to remember these two think of this:
Cardinal = counting
Ordinal = ordering
Let's take a look at a few more examples:
Sam is third in line (We are discussing the order of people in line, Sam happens to be the 3rd.)
Ashley was awarded first place at the Science Fair. (She was ranked 1st out of everyone at the fair)
How many people did you invite to the party? I invited 10 people (The quantity of people- 10 people)
There are 5 books I need for school this year. (How many books? 5 books)
So now tell me...
Have you won an award? What place were you?
What is todays date?
How many countries have you visited?
Tell me what place the following people are in line: Sal, Sarah, Bill
Henry, Sam, Sal, Ed, Sarah, John, Jen, Jack, Terry, and Bill
What's the first thing you do when you wake up? Second? Third...?
