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

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).

**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’**

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.
