Even And Odd Numbers

Odd and Even Numbers for Class 3 Math

In previous classes, the students have already read about odd and even numbers. Here we will recall their definitions and discuss the arithmetic rules for them.

Here students will learn to

• Classify numbers as even or odd numbers
• Predict the result of the sum or difference between odd and even numbers.

 

The learning concept is explained to class 3 students with examples, illustrations and a concept map. At the end of the page, two printable odd and even numbers worksheets with solutions are attached for the students.

Download the worksheets and solutions to assess our knowledge of the concept.

We can classify every number into even and odd numbers. A number can either be an even number or an odd number.

 

What Are Even Numbers?

Numbers having 0, 2, 4, 6, or 8 at ones place are called even numbers.

Even numbers are divisible by 2.

Examples: 14, 42, 56, 108, 230 etc.

 

What Are Odd Numbers?

Numbers having 1, 3, 5, 7, or 9 at ones place are called odd numbers.

Examples: 13, 47, 65, 117, 267 etc.

Arithmetic Rules for Odd and Even Numbers:

• Sum of two even numbers is always an even number.

Even + Even = Even

Examples: 16 + 12 = 28

• Sum of two odd numbers is always an even number.

Odd + Odd = Even

Examples: 13 + 17 = 30

• Sum of an odd number and an even number is an odd number.

Even + Odd = Odd

Examples: 24 + 35 = 59

• Difference of two even numbers is an even number. Difference of two odd numbers is an even number.

a) Even – Even = Even          b) Odd – Odd = Even

Examples: a)14 – 12 = 2           b) 105 – 101 = 4

• Difference of an even number and an odd number is an odd number

Even – Odd = Odd          Odd – Even = Odd

Examples: a) 36 – 23 = 13          b) 45 – 34 = 11
