3. PLACE VALUE

4. What is Place value? - In math, every digit in a number has a place value.  - A Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.  

5. Here’s an example showing the relationship between the place or position and the place value of the digits in a number. In 13548, 1 is in ten thousands place and its place value is 10,000, 3 is in thousands place and its place value is 3,000, 5 is in hundreds place and its place value is 500, 4 is in tens place and its place value is 40, 8 is in ones place and its place value is 8.

6. Understanding the place value of digits in numbers helps in writing numbers in their  expanded form . For instance, the expanded form of the number above, 13548 is 10,000 + 3,000 + 500 + 40 + 8.   A place value chart can help us in finding and comparing the place value of the digits in numbers through millions. The place value of a digit increases by ten times as we move left on the place value chart and decreases by ten times as we move right.

7. Here’s an example of how drawing the place value chart can help in finding the place value of a number in millions. In 3287263, 3 is in millions place and its place value is 3000000, 2 is hundred thousands place and its place value is 200000, 8 is in ten thousands place and its place value is 80000, 7 is in thousands place and its place value is 7000, 2 is in hundreds place and its place value is 200, 6 is in ten place and its place value is 60, 3 is in ones place and its place value is 3.

8. The place value of digits in numbers can also be represented using base-ten blocks and can help us write numbers in their expanded form.  Here’s how the number 13548 can be represented using base-ten blocks.

9. Transform the given numbers from standard to word form GROUP 1 GROUP 2 - 234983 - 456781 - 537681 - 312893 - 167929 - 890261 -389212 - 691289
