Even and Odd Numbers (Definition, Examples, Game and Worksheet)

When we start counting odd and even numbers, the first number is odd number then comes the even number.

Color the correct number of objects. Ring the even numbers and cross the odd numbers:

Two objects form a pair. Thus, one object does not form any pair. If there are three objects, there is one pair and one object is left. If there are four objects, these form two pairs. If there are five objects, these form two pairs and one object is left. If there are six objects, these form three pairs. If there are seven objects, these form three pairs and one object is left. If there are eight objects, these form four pairs. If there are nine objects, these form four pairs and one object is left. If there are ten objects, these form five pairs and so on.

Even Numbers:

The numbers that make pairs are called even numbers. No remainder is left, when an even number is divided by 2.

For example: 2, 4, 6, 8, 10, ……… so on. When these numbers are divided by 2 they have no remainder left.

Odd Numbers:

The numbers that have one left over when divided by 2 are called odd numbers.

For example: 1, 3, 5, 7, 9, ……… so on. When these numbers are divided by 2 they have one left over.

Note: Ring (i.e. ⃝) to show the even numbers in the picture chart given above. Cross (i.e. X) to show the odd numbers.

Pairs:

Things or objects that are in twos are also, said to be in pairs.
