Place Value Relationships
Numbers are grouped in periods or families. The number families are ones, thousands, millions, etc. There are three places in each number family: ones, tens, and hundreds.
Numbers can be expressed in different ways:
- The standard form of a number is written in numbers. For example: 1,234,567.
- The word name of a number is written in words. For example: one million two hundred thirty four thousand five hundred sixty seven.
- Expanded form is the number written as the amount of each place value added together. For example: 1,000,000 + 200,000 + 30,000 + 4,000 + 500 + 60 + 7.
Any number in our base-ten numeration system can be written by using one or more of the digits 0,1,2,3,4,5,6,7,8, and 9. All digits take on different values depending on their position or places in the number.
Look at the following number and answer the following questions:
Watch the Video about Place Value and try to sing along.
Place value and the digit determine the size (value) of the number. For example: a 7 in the tens place is smaller than a 1 in the hundreds place because 7 tens = 70 and 1 hundred = 100.

I Can Statements:
I can determine what numbers are the largest and smallest.I can order numbers from least to greatest.I can order numbers from greatest to least.

4,567 4,843 or 4,567 < 4,843
Use your graph paper to compare numbers
Compare 41,572 and 43,245
Both have a 3(red) in the millions place. Go to the next place the digits are different.
Compare those two 6 < 9.
Therefore, 3,689,523 > 3,487,624
