Whole Numbers and Ordinal Numbers: Introduction

In the unit Whole Numbers and Cardinal Numbers, we learned about numbers - whole numbers - from zero to one million: what these numbers are and how to write them. We learned that we write a whole number that tells us how many of something that we have, the number is called a cardinal number.

In this unit Whole Numbers and Ordinal Numbers, we learn how to write numbers when they are used to describe an order, such as rank or position. An example is to say that something is third from the right. Numbers when written that describe an order are called ordinal numbers.
