Four Digit Numbers

In class II we had learnt numbers up to 3-digits. Now let us learn

numbers bigger than 3 digits. We know that largest 3-digit number is 999.

Let us find the successor.
To do this we add 1 to 999.

H T O

9 9 9
+ 1
1 0 0 0

We get a new number. We call it one-thousand.

Also, we get a new place value.

We will call it thousands place.

We write ‘Th’ for it.

The numeral for one-thousand is 1000.

It is the smallest four-digit number.

Let us count further in ones.

1 more than 1000 is 1001 2 more than 1000 is 1002
3 more than 1000 is 1003 4 more than 1000 is 1004

5 more than 1000 is 1005 6 more than 1000 is 1006
7 more than 1000 is 1007 8 more than 1000 is 1008

9 more than 1000 is 1009 10 more than 1000 is 1010

Now let us count further in tens.

10 more than 1000 is 1010 20 more than 1000 is 1020

30 more than 1000 is 1030 40 more than 1000 is 1040

50 more than 1000 is 1050 60 more than 1000 is 1060

70 more than 1000 is 1070 80 more than 1000 is 1080

90 more than 1000 is 1090 100 more than 1000 is 1100
