Ordinal Numbers From 1-20 (With Flashcards)

Nothing beats the thrill of coming first in a competition. But, so many new learners of English have problems telling people about their accomplishments. This lesson should help you teach them about first, second, third, and all of the ordinal numbers from 1-20.

Before you teach ordinal numbers, your child should already be familiar with basic numbers. We have a lesson on basic numbers from 1-20 for you to use, so make sure to check that out first.

As well, in this post, we have some downloadables for you, including a poster and flashcards. You can find those after our list. 

What is an ordinal number?

An ordinal number is used to show the position of something in a list. These lists can be of people, like in a race, or it could be of things, like ingredients in a recipe.

Each number has an ordinal version. For example, the ordinal number of 1 is first, 2 is second, and 3 is third. In our list that takes you from 1-20, all of the numbers (except 1-3) use the ending th. So, 4 becomes fourth, and twelve becomes twelfth. 

Ordinal numbers from 1-20 are the hardest to learn, but past 20, ordinal numbers become easier as they begin to follow a set pattern. For example, 2 becomes second, 22 becomes twenty-second, and 33 becomes thirty-second.

How do you write ordinal numbers?

Ordinal numbers can be written in one of two ways. One way includes the number, and the other is fully written out in words. It is important to note that both are said the same way. 

The number version starts with the number and ends with a short form of the ending. So the written version of fifth becomes 5th. Or, the written version of first becomes 1st. You can see both versions in the chart above or below.

Final Thoughts on Ordinal Numbers

Ordinal numbers are an often overlooked part of English. This is unfortunate as we use them every day. We suggest that you start children learning this early. Especially first, second, and third as, throughout the day, they will undoubtedly use at least one of them.

If you are looking to practice ordinal numbers, any kind of game provides a great opportunity to review. Watch or compete in a race and announce the winners. Or, do some cooking and have everyone list out the steps in how you make your favorite treat.

Good luck with the teaching, and if you have any questions, feel free to comment below, and we will help however we can.
