DAV Class 4 Maths Chapter 1 Worksheet 5 Notes
To read the big numbers, we group the places into periods.
Six places are grouped into 3 periods
The first 3 places from the right is ones, tens and hundreds make the period.
The next 2 places is one thousand and ten thousand make thousands periods. The 6th place comes in lakhs period.
To separate the periods, we leave the space or insert commas in between the periods e.g. 576420 is written as 5 76 420 or 5,76,420.
