Q2. Which is the 3-digit smallest number?

Ans: 100

Q3. Which is the 3-digit greatest number?

Ans 999

Q4. Which is the 4-digit smallest number?

Ans: 1000

Today you will learn counting beyond 999.

As you know the greatest 3-digit number is 999 and 4-digit counting starts from 1000.It

will be followed as:-

1000= One thousand

1001=One thousand one

1002= One thousand two

1003= One thousand three.

1004= One thousand four………………so on.

Let’s revise randomly.

1010= One thousand ten

1011 = One thousand eleven.

1015= One thousand fifteen.

1020= One thousand twenty.

1100= One thousand one hundred.

1115= One thousand one hundred fifteen.

1225 = One thousand two hundred twenty five.

2000 = Two thousand

2050=Two thousand fifty.

3000=Three thousand

4000= Four thousand

5000= Five thousand

6000= Six thousand

7000=Seven thousand

8000= Eight thousand

9000= Nine thousand

9999= Nine thousand nine hundred ninety nine

9999 is the 4-digit greatest number.

Topic: Place Value and Face Value

Face Value is the digit itself.

In 456 Face value of the 6 is 6, the face value of 5 is 5 and the face value of 4 is 4.

Place Value is the value of the digit according to its “place” or “position” in the

number!

Example :-

TH H T O 2 7 4 3

7

In 2,743

Note: - The number that is at ones place their place value and face value will be always

same.

Topic: Expanded and Standard form

Expanded form: - The sum of the place values of its digits is called the expanded

form.

Example: - 8,872 = 8000 + 800 + 70+2

9, 251 = 9000 + 200 + 50 + 1

Standard form: - A number in its original form is called standard form of the

number.

Example:- 5000 + 300 + 20 + 3 = 5,323

4000 + 20 + 5 = 4,025

(d) 3000 + 600 + 80 + 5= _______________

Successor – It means you have to write the number that comes just after the given

number or you have to add 1 in the given number.

For example: - Write the successor of the given number.

(a) 5,339 = The successor of the number is 5,339+1= 5,340.

(b) 1528 = 1528 + 1 =1529

Predecessor:- – It means you have to write the number that comes just before the

given number or you have to subtract 1 from the given number.

For example: - Write the predecessor of the given number.

(a) 5,339 = The predecessor of the number is 5,339-1= 5,338

(b) 1528 = 1528-1 = 1527

Even Numbers

The numbers having 0,2,4,6 and 8 at once place they are

called even numbers.

For examples:- 2, 4, 6 and 8 are even numbers.

When numbers are large we observe only ones place to

identify the number whether it is even or not. For even

numbers there should be 0,2,4, 6 and 8 at ones place.

For Examples:- 12 , here 2 is at ones place so it is even

Number.340, 242, 1254, 500, 318, 512, 554, 6992, 1110

are examples of even numbers.

13

Odd Numbers

The numbers having 1,3,5,7 and 9 at once place they are called

odd numbers.

For examples:- 1, 3, 5, 7 and 9 are odd numbers.

When numbers are large we observe only ones place to

identify the number whether it is odd or not. For odd numbers

there should be 1,3,5, 7 and 9 at ones place.

For Examples: - 11, here 1 is at ones place so it is odd Number.

341, 243, 1255, 509, 311, 517, 5583, 6991, 1115 are examples

of odd numbers.

CH-ADDITION

Addition means finding the total of two or more

numbers. This total is called Sum.

The numbers which are added are called addends.

Properties of Addition

Two or more numbers can be added in any order.

25 + 10 =35

10 +25 =35

20 + 10 + 5 = 35

5 +20 +10 = 35

Adding 0 to a number gives the same number.

4567 + 0 = 4567

289 + 0 = 289

6550 + 0 = 6550

Adding 1 to a number gives the next number.

899 + 1 = 900

25 + 1 = 26

5,682 + 1 = 5,683

4,590 + 1 = 4,591

23

Adding 10 to a number increases the tens place by 1

52 + 10 = 62

450 + 10 = 460

4853 + 10 = 4863

8,992 + 10 = 9,002

758+ 10 =768

Adding 100 to a number increases the hundred place by 1.

5866 + 100 = 5966

2000+100 = 2100

9,632 + 100 = 9,732

9,682 +100 = 9,782

Adding 1000 to a number increases the thousand place by 1.
