Cardinal numbers tell us about quantity. They are often used for counting. When we have a number of items and we need to tell their quantity we use cardinal numbers for example one, two, three, four, five and so on.
See the fact file below for more information on the cardinal numbers or alternatively, you can download our 28-page Cardinal Numbers worksheet pack to utilise within the classroom or home environment. This worksheet is broken down by Beginner, intermediate and advanced meaning you can choose the complexity level for your student.
Key Facts & Information
- Cardinal numbers tell us about quantity. They are often used for counting.
- Cardinal numbers: one, two, three, four, …..
- Example: Eric bought two 12 apples.
What are cardinal numbers?
- The first concept taught to children in mathematics is the concept of cardinal numbers.
- They serve as a foundation for the building of other concepts. When we have a number of items and we need to tell their quantity we use cardinal numbers for example one, two, three, four, five and so on.
- In short whenever someone asks us about quantity of something we use cardinal numbers. They are also known as “ counting numbers”.
- For example :
There are 20 students in the class.
Emma bought 6 new story books.
Eric needs 10 more days to complete the task.
- On the other hand when we want to tell the position of something we use ordinal numbers such as first, second, third, fourth, fifth and so on.

Applications of cardinal numbers
- As previously mentioned cardinal numbers serve as foundation for the building of all other concepts.
- Initially we learn different types of counting and all of them use cardinal numbers. Later we learn addition, subtraction, multiplication and division.
- When learning the basics of these concepts we use cardinal numbers.
- We count using cardinal numbers.
- We learn to add and subtract using cardinal numbers.
- We learn to multiply and divide using cardinal numbers.
- Hence these numbers are like a backbone and provide support to the subject.
- Write the following cardinal numbers in words:
- In the list given below identify the cardinal numbers:
- In the list of above given numbers the following are cardinal:
- The remaining are ordinal numbers:
- Ordinal numbers tell us about the position.
- In a classroom there are 10 boys and 13 girls. What are the total number of students present?
boys = 10
girls = 13
total students = boys + girls
total students = 10 + 13
total students = 23
- Hence the total number of students in the classroom are 23 or twenty-three.
- Amy has 2 boxes of crayons, 3 boxes of color pencils, 1 box of pastels and 5 boxes of glitter pens. How many total boxes does Amy have?
crayons = 2
color pencils = 3
pastels = 1
glitter pens = 5
total boxes = crayons + color pencils + pastels + glitter pens
total boxes = 2 + 3 + 1+ 5
total boxes = 11
- So Amy has 11 ( eleven ) boxes.
- In the summer season the school decided to take the students of a class for peach picking. The number of peaches collected by each student is given in the table below:
- Who collected the most peaches?
- Did Kate collect more peaches than Robin?
- How many peaches did Joel and Malcolm collect in total?
- Which two students collected equal number of peaches?
- How many peaches did Jack and Pearl collect in total?
When we compare all the cardinal numbers in the list we see that Nelson collected 15 peaches. Hence Nelson collected the most peaches.
Kate collected 9 peaches whereas Robin collected 10 peaches. This means that Kate did not collect more peaches than Robin.
Joel collected 10 peaches.
Joel = 10
Malcolm collected 8 peaches.
Malcolm = 8
So the total number of peaches collected my Joel and Malcolm is given by :
total peaches = 10+8
total peaches = 18
Hence they collected 18 peaches.
Pearl and Malcolm both collected 8 peaches. Hence they collected equal number of peaches.
Jack collected 12 peaches.
Jack = 12
Pearl collected 8 peaches.
Pearl = 8
So the total number of peaches collected by Jack and Pearl is given by:
total peaches = 12 + 8
total peaches = 20
