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.

When we write numbers, the position (or "place") of each digit
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

But what if we continue past Units/Ones? What is 10 times smaller than 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"

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!
