Working With Cardinal Numbers Worksheets

This is the classification of numbers that often escapes students. If we are really being honest, when I got to my first Kindergarten class, I needed a refresher too. Cardinal numbers are the digits that we count with. They tell us how much or the quantity that we have of something. Examples would be: how many jellybeans are in the jar or the number of students that are out sick today. It is important to remember that these are whole numbers and represent whole units. In this section we will walk students through using these counting values and have them quantify all different types of situations.

What Are Cardinal Numbers?

Cardinal numbers are generally referred to as counting numbers. Or to put it simply, the digits that are used for counting are known as cardinal values. Cardinal numbers can help us identify how many of something is there, such as two, four, or five. Suppose you are asked to count the baseballs, footballs, soccer balls and tennis balls that were given to you in a line. This gives you the quick ability to point out the exact ball you are referring to.

They start from 1. Fractions and decimals are not classified as cardinal numbers as they represent a part of a group. Cardinal numbers tell us about the cardinality of certain groups or sets of objects that means it shows how many objects are there in a set or group.

What Are Ordinal and Nominal Numbers?

Other types of numbers are often confused with cardinal numbers. These are ordinal and nominal numbers. Nominal numbers name something. They are used to identify something and do not define the rank or quantity of something - for example, zip code 033242, jersey number 45. Ordinal numbers show the position of something mentioned in the list of some kind. For example, words like second, third, fourth, etc. They are often used to define the order in which a contest was won such as the Olympics.
