# Odd Numbers For Children To Improve Math Skills

Numbers are the backbone of mathematics. Learning numbers is an important step in a kid’s education. They are used to count or measure things and play a very important role in daily life and mathematics. Learning numbers help children understand simple math concepts from an early age, which hugely impacts their confidence in math skills. This confidence paves the way for a more easy-going learning process in the future.

Numbers are further divided into two types – even numbers and odd numbers, and it is important to teach kids about both types of numbers.

As the concept of numbers is huge, we have only covered maths odd numbers in this article. The details covered are the definition of an odd number, identification of odd numbers, types of numbers, odd numbers chart, properties of odd numbers and some solved examples. Let’s take a look at it!

## What Are Odd Numbers?

Let’s take a look at the odd number’s definition for children.

Odd numbers are numbers that cannot be divided by 2 or cannot be divided into two parts equally. These numbers always leave the remainder of 1 when divided by 2.

For example – 1, 3, 5, 7, 9, etc.

## Types Of Odd Numbers

There are two types of odd numbers – Consecutive odd numbers and composite odd numbers. Let’s read about them in a little detail.

### 1. Consecutive Odd Numbers

These are the odd numbers that are listed in sequence of their order. Let’s take a look at the example given below to understand this.

Example: Let n be an odd number.

The numbers n and n + 2 will be grouped under the category of consecutive odd numbers.

These numbers will always have a difference of 2 between them and are consecutive in nature. For example, 5 and 7, 11 and 13, 37 and 39, and so on.

### 2. Composite Odd Numbers

These are the odd numbers that are not prime numbers and are formed by the product of two smaller positive odd integers.

Examples of composite odd numbers: are 9, 15, 21, 25, 27, and so on.

## How To Identify Odd Numbers?

It is quite easy to identify numbers that are odd. All kids need to do is look at the one’s digit. If the one’s digit is 1, 3, 5, 7, or 9, the number is odd. If not, it is an even number.

## Chart Of Odd Numbers From 1 To 100

Here is the chart of odd numbers from 1 to 100 for children. You can take a print of this chart and paste this into your child’s room for them to learn it easily.

## Odd Numbers (1 To 100)

There are a total of 50 odd numbers between 1 to 100. All odd numbers between 1 to 100 are:

 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 61 63 65 67 69 71 73 75 77 79 81 83 85 87 89 91 93 95 97 99

 101 103 105 107 109 111 113 115 117 119 121 123 125 127 129 131 133 135 137 139 141 143 145 147 149 151 153 155 157 159 161 163 165 167 169 171 173 175 177 179 181 183 185 187 189 191 193 195 197 199

## Important Properties Of Odd Number

Here are the properties of odd numbers that you can teach your little one.

When we add two odd numbers, the result is always an even number. Therefore, the sum of odd numbers is always an even number.

For example, 7 + 5 = 12

Where 7 and 5 are odd numbers, and their sum, 12, is an even number.

### 2. Subtraction

When we subtract two odd numbers, the result is always an even number. Therefore, the difference between any two odd numbers is always an even number.

For example, 7 – 5 = 2

Where 7 and 5 are odd numbers and their difference, 2, is an even number.

### 3. Division

When we divide two odd numbers, the result is always an odd number.

For example, 33/11 = 3

Where 33, 11 and 3 are odd numbers

### 4. Multiplication

When we multiply two odd numbers, the result is always an odd number. Therefore, the product of any two odd numbers is always an even number.

For example, 3 X 11 = 33

Where 3 and 11 are odd numbers, and their product 33 is also an odd number.

## Solved Examples Of Odd Numbers

Let’s take a look at solved examples of odd numbers for children.

1. Are the following numbers odd?

• 27
• 5 + 3
• 30 – 17

Solution:

• 27 is not divisible by 2, so it’s an odd number.
• 5 + 3 = 8, which is divisible by 2. So, it’s not an odd number.
• 30 – 17 = 13, which is an odd number.

2. Fill in odd numbers:

• _, 2, _, 4, _, 6, _, 8.
• _, 72,_, 74, _, 76, _.
• 100, _, 102, _, 104, _, 106.

Solution:

• 1, 2, 3, 4, 5, 6, 7, 8.
• 71, 72, 73, 74, 75, 76, 77.
• 100, 101, 102, 103, 104, 105, 106.

3. Find the sum of the largest and the smallest odd number of two digits.

Solution:

Smallest two-digit odd number = 11

Largest two-digit odd number = 99

Sum of both the numbers = 11 + 99 = 110

4. True or false?

• The sum of two odd numbers is always an odd number.
• The smallest odd number is 7.

Solution:

• False. The sum of two odd numbers is always an even number.
• False. The smallest odd number is 1.

Here are some practice questions for your little one with answers on odd numbers.
