Place Value for Grade III

Hello friends, today we are going to learn about place value and whole numbers. Here I am going to tell you the best way of understanding place value and whole numbers which comes under the cbse board syllabus.
First we discuss about the Place value to calculate math answers. In our Decimal numbers system, the value of digit depends on its place. In the number each place has a value of 10 times the place to its right. A number in standard form is separated into group of three digit using commas. Each of these group is called period. Place value of digit is determined by its position in a number, the name of the place or location of a digit in a numbers. Place value is positional system of notation in which the position of a number with respect to a point determines its value. In the decimal system, the value of the digit is based on the number ten. Each position in a decimal number has a value that is a power of 10. A decimal point separates the non-negative power of 10 (100=1 , 102=100, 103=1000). The idea of the place value is at the heart of our numbers system, First however, a symbol for nothing or zero had to be invented. Zero holds the place of particular value.  When no other digit goes in that position. For example the number “100” in words means one hundred. No one’s without a symbol for nothing our decimal number system wouldn’t work.To get more information about it click here:

Beginning with one place at the right, each place value is multiplied by increasing power of 10, the value of the first place on the right is “one ” the value  place to the left of it is ten which is 10 times 1. The place to the left of the ten place is hundred, which is 10 time 10. Place value number can be represented in many ways. But standard form is usually the shortest and easiest. Here are some numbers expressed in different form with their standard form show alongside.
We take one number 145, have three digits. Each digit is a different value in this value “1” refer to the hundredth place the “4” refers to the ten place and the “5” refers to the one place is succeeded.
Place value is an important concept that is often misunderstood and misplaced. Place value the particular power of the base of continue system that is represented by a particular position in a place value Notation for example: - unit, ten, hundred, etc. The definition correctly places the concept of place value as an attribute of positional system not solely the decimal one.  Place value the value given to a digit by virtue of the places it occupies in the number relative to units place. Importance of place value has been emphasized in the NCTM standards.  The place value is important to understand numeration system.

In above article we discuss about the place value and whole number and if you want to know about Properties of numbers in Grade III and Place value whole numbers then you can refer to the various sites available on Internet.
