The Tale of Odd and Even Numbers
Once upon a time, in the world of numbers, there lived two types of digits – the odd numbers and the even numbers. Let’s embark on a journey to understand their enchanting story.
Coloring the Correct Numbers
In this magical world, the first number to grace the stage is an odd number. It is followed by an even number. Our task is to count and color the correct number of objects.
Forming Pairs
In this realm, objects have a tendency to form pairs. However, there are some loners who do not have a partner. When there are three objects, one pair is formed, leaving one object alone. With four objects, two pairs are formed. As the number of objects increases, so do the pairs – five objects make two pairs and leave one object alone, six objects make three pairs, and so on.
The Even Numbers
In this enchanting story, numbers that form pairs are called even numbers. When divided by 2, they leave no remainder. For instance, let’s take a look at the numbers 2, 4, 6, 8, and so on. When divided by 2, they have no remainder. These numbers are the stars of the show. We ring ⃝ them in the picture chart above to showcase their evenness.
The Odd Numbers
The odd numbers, on the other hand, are a bit peculiar. When divided by 2, they leave one left over. These numbers, such as 1, 3, 5, 7, and so on, are the ones that make us raise our eyebrows. They are stunning in their oddity. We cross them X in the picture chart above to signify their uniqueness.
Pairs in Everyday Life
Pairs are not limited to numbers in this mystical world. In fact, things or objects that come in twos are also considered in pairs. Take two goats, for example. They are together, forming a pair. And what about socks or scissors? They too come in pairs. This story teaches us to appreciate the beauty of pairs in our everyday lives.
Discovering Even and Odd Numbers
Let’s dive deeper into our understanding of even and odd numbers. Even numbers are those that can be put into pairs. If a number has its ones digit as 0, 2, 4, 6, or 8, it is an even number. For example, 2, 4, 6, 8, 10, 12, 14, and so on, are all even numbers. They are the harmonious pairs in our numerical world.
Odd numbers, on the other hand, cannot be put into pairs. If a number has its ones digit as 1, 3, 5, 7, or 9, it is an odd number. For instance, 1, 3, 5, 7, 9, 11, 13, and so on, are all odd numbers. They add a touch of mystery and intrigue to our numerical realm.
Let’s Put Our Knowledge to the Test
Now, let’s put our newfound knowledge to the test with some questions and answers on even and odd numbers.
1. Write the even numbers up to 30.
Answer: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, and 30.
2. Write the odd numbers from 15 to 35.
Answer: 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, and 35.
3. Find the even number in each group and write it in the placeholder.
(i) 43 67 1217 21 ▢
Answer: The even number is 1217.
4. Find the odd number in each group and write it in the placeholder.
Discuss and write: which is the first odd number?

Summary: Even and Odd Numbers | Uncover the World of Even Numbers
When counting odd and even numbers, the first number is always odd, followed by an even number. In this article, we learn about pairs, even numbers, and odd numbers. Even numbers can be divided by 2 without leaving a remainder, while odd numbers always have one left over. The article also provides examples and answers to questions related to even and odd numbers.
Frequently Asked Questions
What are odd and even numbers?
Odd and even numbers are mathematical classifications used to categorize integers.
How can odd numbers be identified?
Odd numbers are integers that cannot be evenly divided by 2. They always have a remainder of 1 when divided by 2.
How can even numbers be identified?
Even numbers are integers that can be evenly divided by 2. They always have a remainder of 0 when divided by 2.
What is the importance of odd and even numbers?
Odd and even numbers have various applications in mathematics, such as in number patterns, divisibility rules, and calculating probabilities.
Can odd and even numbers be negative?
Yes, both odd and even numbers can be positive or negative integers. The classification is based on divisibility by 2, regardless of the sign.
Are prime numbers considered odd or even?
Prime numbers are only divisible by 1 and themselves, so they are not classified as odd or even. They form a separate category in number theory.
How to recognize a digit as odd or even?
For single-digit numbers, if the digit is 0, 2, 4, 6, or 8, it is even. If it is 1, 3, 5, 7, or 9, it is odd.
Can decimal numbers be classified as odd or even?
No, odd and even classifications are not applicable to decimal or fractional numbers. They are specific to integers only.
