How Does Place Value Relate to The Expanded Form of Numbers?
Place value is an important concept in mathematics. It is one of the first major concepts the kids are taught in school when studying numbers and counting. It helps in laying the grounds for understanding the expanded form of numbers.
Every digit in a number sits in a unique position and holds value. Together these digits make up the value of the number. The smallest place value is the unit place. To understand place value, take the example of the number; 1,243.

1: 1 in the number sits at the thousand's place

2: 2 in the number sits on the hundred's place

4: 4 in the number sits in ten's place

3: 3 in the number sits on the unit place

According to the place value, there are one thousand, two hundreds, four tens, and three ones that are adding to make the number 1,243. The place value helps in writing a number in its expanded form. Now that we have understood the place values of all digits in the number 1,243, we can write it down in an expanded form;
1,243=1000+200+40+3
These worksheets display to students how to relate place value to expanded number form.
