Place Value
Thousands, Ten Thousands, and Hundred Thousands
Lets Review the place value positions you should already be familiar with: Ones, Tens, and Hundreds.
We would need 10 hundred slabs to equal 1 Thousands cube
10 hundreds = 1 Thousands
We use a comma to separate groups of 3 numbers!

Now, lets take a look at the next three place value positions. First we have the Thousands position.
Next is the TEN THOUSANDS position.
Again we go in groups of 10…
10 thousands = 1 Ten Thousands

Finally, there is the HUNDRED THOUSANDS position.
Again we go in increments of 10…
10 ten thousands = 1 Hundred Thousands
How many thousands would it take to equal 100,000?
_________ thousands = 1 Hundred Thousands

Now lets look at the first three place values after the decimal point.
If we divided 1 unit into 10 equal pieces we create tenths.
10 tenths = 1 ones
All decimal place values end in “ths”.
