Math, Odd Numbers Even Numbers Worksheet – Fall

Odd numbers and even numbers are an easy and fun way to understand math! Even numbers are numbers like 2, 4, 6, 8, and 10. They can be divided into two equal groups with no leftovers, like splitting 8 apples between two friends. Odd numbers, like 1, 3, 5, 7, and 9, are a little different. When you try to divide them into two equal groups, there’s always one left over, like having 5 cookies for two people and one cookie left. You can tell if a number is odd or even by looking at the last digit. If it’s 0, 2, 4, 6, or 8, it’s even. If it’s 1, 3, 5, 7, or 9, it’s odd. Isn’t that cool?

We can examine natural numbers by considering some objects. Let’s take the socks we use daily in this regard and learn the odd and even natural numbers. 

• One sock: 1 (Odd)
• Two socks: 2 (Even)
• Three socks: 3 (Odd)
• Four socks: 4 (Even)
• Five socks: 5 (Odd)

What do we notice when we examine the socks above? Some natural numbers are written as odd and some of them are written as even. 

Odd Numbers: 1, 3, 5, 7, 9,

Even Numbers: 0, 2, 4, 6, 8

Based on these numbers we counted, we can understand the odd and even numbers on socks. For example, when we count the socks as even, we see that some of them are left with only one. So some socks are left alone. Socks that are left out when we match are known as odd. Matching socks are known as even.
