Day Saturday-4.4.2020
Dear Students,
In previous class you have learnt about Place and Place Value of a digit for 6-digit
numbers. Now we will learn about how to find period of a digit in a 6 -digit number.
The six places are grouped into three periods.
Periods
Lakhs Thousands Ones
Lakhs Ten Thousands Hundreds
Thousands Tens
Ones
The first 3 places from right are Ones, Tens, and Hundreds make the ‘Ones’ period.
The next two places Thousand & Ten Thousand make ‘Thousands’ period.
Sixth place comes in the ‘Lakhs’ period.
In order to separate the periods, we put commas (,) between the periods-
Example: 642395 ---> 6, 42,395
Let’s learn to find Period, Place & Place value of a given number:
Periods LAKHS THOUSANDS ONES
Ten
Lakh Thousands Hundreds Tens Ones
Place Thousands
(1,00,000) (1,000) (100) (10) (1)
(10,000)
Numbers
5,86,201 5 8 6 2 0 1
2,90,150 2 9 0 1 5 0
For further understanding, let us study some solved examples-
1. What is period, place and place value of 6 in 5,86,201?
Period: Thousands
Place: Thousand
Place Value: 6,000 (6 x place)
2. What is the period, place and place value of 9 in 2,90,150?
Period: Thousands
Place: Ten Thousand
Place Value: 90,000 (9 x place)

While reading the numerals of a number, all the digits in the same period are read together
and name of the period is read along with them.
