# Ordinal Numbers

## Introduction

Read these sentences.

**The cookies are kept in the \(3^\text{rd}\) drawer from the top.
The orange dress is the \(7^\text{th}\) one from the right.
The football is kept in the **

*carton box from the left.*

**\(3^\text{rd}\)**All these sentences have one thing in common.

They all talk about the **position** of certain objects (cookies, orange dress, football).

This is the main element in the discussion of ordinal numbers.

## Ordinal Numbers

An ordinal number tells the numerical position of an object in a list. In other words, it indicates the order of things or objects, such as first, second, third, fourth, and so on.

An ordinal number usually ends in “th.”
