Hello kids in grade IV, mathematics is a very wide subject. We deal with so many topics like math fractions that are used in a lot of fields. Introduction to whole number - A whole number is a number which is not in the decimal, percentage and fraction form. Numbers such as 1, 2, 3 etc. are whole numbers.
Whole numbers are a collection of unique numbers which contain 0 to 9 digits. Whole numbers are 0,1,2,3,4,5,6,7,8,9. Each digit has a place value in every whole number.
When we read the numbers starting from the left, the digits are followed by the period name. Period names do not include 'ones', 'tens'. Now we take some examples of whole numbers
1. 23,552 Read the number twenty three thousand, five hundred, fifty two.
2. 7,620 Read the number seven thousand, six hundred twenty. (read here for more on whole numbers)
When writing the numbers we can use the commas. Commas are separators for a group of digits. When we use the commas, numbers are easy to read.
We can take some more examples:-
Write the number in words: the number is 26,233,123
The solution is: twenty-six million two hundred thirty-three thousand one hundred twenty-three.
When reading and writing whole digit we cannot use word 'and’. And word is only used for decimal points.
At last I want to say that whatever information of whole numbers I gave above is correct and will be truly helpful for the IVth standard.
In upcoming posts we will discuss about Place value whole numbers and Number systems in Grade V. Visit our website for information on board of secondary education AP
