The Power of 10
The Power of Ten
The Power of 10 is a concept we need to continue to work on. :)
Power of 10 - each place in a place value chart has a value that is 10 times as great as the place value to its right and 1/10th the size of the place value to the left.
But what if we continue past Units/Ones? What is 10 times smaller than Units/Ones?
Here are some games to practice this skill:

We will continue to work on this concept in small group. Let me know if you need any help!
Power of 10 - each place in a place value chart has a value that is 10 times as great as the place value to its right and 1/10th the size of the place value to the left.
When we write numbers, the position (or "place") of each digit
is important.
is important.
In the number 327:
· the "7" is in the Units/Ones position, meaning just 7 (or 7 "1"s),
· the "2" is in the Tens position meaning 2 tens (or twenty),
· and the "3" is in the Hundreds position, meaning 3 hundreds.
"Three Hundred Twenty Seven" |
As we move left, each position is 10 times bigger! | |
Example: Hundreds are 10 times bigger than Tens |
... and ...
As we move right, each position is 10 times smaller. | |
From Hundreds, to Tens, to Units/Ones |
1/10 ths (Tenths) are!
But we must first write a decimal point, so we know exactly where the Units position is: |
"three hundred twenty seven and four tenths"
