Brief Description Place value is one of the first essential topics in the number sense in early grades. The value indicated by a digit in a number based on its position in the number is known as place value. Those positions or locations start from a unit place or the one’s position. The number of places the digit lies to the right or left of the decimal point determines the place value. The order of place value of digits of a number of right to left is ones, tens, hundreds, thousands, ten thousands, hundred thousands, and so on.
Importance of the Topic A place value is assigned to each digit of a number based on a Base Ten system in math. Understanding this topic is essential for learning Mathematics. Therefore, knowing the positions or place values of digits in a number is a starting point to help learners read and write numbers correctly. It is also a prerequisite to compare and order whole numbers and decimals and write them in expanded form. Without knowing the place values of digits in a number, you cannot tell how much a money bill is and how big or small a number is from another number. Learning place value helps learners to develop number sense.
Application of the Learned Topic in Life Place value is considered as the core of our number system. It has many practical applications in real life. For example, if you buy a book from a bookstore with a price tag of $5.60 and you do not know how much $5.60 costs, how will you pay for it? Learning the concepts of place values, you will also pay and count your change correctly. Another application is when you want to rank the first ten countries in the world with a high population, you will be able to do it because you know the place values of the digits in the number of population. Place value also helps learners to arrange things in order according to their quantities.
