Zero

What is zero?

To show nothing or no object we write 0. We read 0 as zero.

For Example:

What is zero?

                            Cage 1                     Cage 2                      Cage 3

In cage 1 we observe that the cage has 2 birds in it.

In cage 2 we observe that 1 bird flies away and the cage has 1 bird in it.

In cage 3 the second bird also flies away. Now the cage has no bird in it.

Therefore, there is no bird in the cage we write 0.

Let us review the number zero.

3 boys are playing.

One of them runs away.

How many are left?

3 - 1 = 2

One more runs away.

How many are left now?

2 - 1 = 1


This boy also runs away.

How many are left now?

1 - 1 = None


None is written as zero

'0' is read as zero.

1 - 1 = 0

Let’s practice questions on zero (0).

Fill in the blanks:

1. There are four balloons in hand. All the four balloons fly away. How many balloons remain in hand?

4 – 4 = ……………. .

2. There are three rats in a trap. All the three rats run away. How many rats remain in the trap?

3 – 3 = ……………. .

3. There are five birds in the cage. All the five birds fly away. How many birds remain in the cage?

5 – 5 = ……………. .

4. 6 - 6 = _____

5. 9 - 9 = _____

6. 1 - 1 = _____

7. 8 - 8 = _____

8. 2 - 2 = _____

Now we will discuss about math Addition and Subtraction Property of Zero. 

Addition Property of ‘Zero’

Addition Property of ‘Zero’



When we add zero to a number, the number remains the same.

Do orally and play math games on addition

● 0 + 2 = 2

● 4 + 0 = _____       ● 2 + 0 = _____


● 5 + 0 = _____       ● 0 + 4 = _____


● 0 + 6 = _____       ● 0 + 5 = _____


● 9 + 0 = _____       ● 6 + 0 = _____


● 0 + 1 = _____       ● 0 + 9 = _____


● 3 + 0 = _____       ● 1 + 0 = _____


● 0 + 8 = _____       ● 0 + 3 = _____


Subtraction Property of ‘Zero’

There are 2 mangoes in a plate.

Mary does not take any mango.

How many mangoes will be left in the plate?

2 - 0 = 2 (two)

When we subtract zero from a number, the number still remains the same.

Do orally and play math games on subtraction

● 3 - 0 = _____

● 6 - 0 = _____

● 4 - 0 = _____

● 8 - 0 = _____

● 7 - 0 = _____

● 9 - 0 = _____

● 1 - 0 = _____

● 5 - 0 = _____


Math Only Math is based on the premise that children do not make a distinction between play and work and learn best when learning becomes play and play becomes learning.

However, suggestions for further improvement, from all quarters would be greatly appreciated.
