❖ We use 0 to 9 digits to write counting.
❖ The smallest 1-digit number is 1 and the largest 1- digit number is 9.
❖ The smallest 2-digit number is 10 and the largest 2-digit number is 99.
❖ The smallest 3-digit number is 100.
1)The largest 3- digit number is 999.
2)The largest and smallest 4-digit number is formed by adding 1 to 999.
999+1=1000
3)1000 is read as one thousand.
4)1000 is written as
Thousand Hundred Ten Ones (unit)
1 0 0 0
5) The largest 4-digit number is 9999.
6) By adding 1 to the largest 4-digit number we get the smallest 5-digit number.
PLACE VALUE AND FACE VALUE
The place value of a digit depends on the place where it occurs. The face value of a number is what the original value of the number is.
Example Th H T O Face value Place value
8 2 4 3 3 3 ones = 3
4 4 tens = 40
2 2 hundreds =200
8 8 thousands = 8000

Expanded form and Short form
The sum of the place value of the number is called Expanded form.
Example- 5259= 5 thousands+2 hundreds+5 tens+9 ones =5000+200+50+9
Q4)Write the expanded form of the following:-
1)7095=_______thousands+______hundreds+__________tens+_______ones

3)7991=_______thousands+______hundreds+__________tens+_______ones
4)8245=_______thousands+______hundreds+__________tens+_______ones
5)5360=_______thousands+______hundreds+__________tens+_______ones
Q5)Write the short form:-
1) 8thousands+3 hundreds+5tens+0ones=_____________________
2) 7thousands+0hundreds+6tens+2ones=______________________
3) 9thousands+2hundreds+8tens+3ones=______________________
4) 4thousands+7hundreds+4tens+1ones=______________________
