Let’s pretend that place value is like a city!
In the city of place value there are only three houses on each block. There is a driveway
between each block of houses.
Just like in your neighborhood different families live in different homes.
My house-the Sanders
My friend-The Mohr house
In the city of place value, all homes have a different name

Now you should know the place names. Let’s see
what it looks like with numbers.
Remember place value is like a city! Only one number can go in each place just
like one family to a home.
This is what it would look like without the houses.
Do you remember? Click on the digit in the hundreds place?
Fantastique!
Oops! Spend your time and memorize the names of the places.

This is hard. Why don’t we go back a bit and
start back at the basics.
REMEMBER
• A digit is a 1, 2, 3, 4, 5, 6, 7, 8, 9, or 0
• A number can have any number of digits
REMEMBER
• There can only be 3 digits next to each other
• A comma goes in between each set of 3 digits
REMEMBER
• The different places are–Ones
–Tens
–Hundreds
–One-Thousands
–Ten-Thousands
–Hundred-Thousands
REMEMBER
• The place value is determined by saying
The digit &
The place
THE END
