Place Value
Place value is how a digit's position in a number changes what that digit is worth.
Think of it this way
A kitchen tray has three slots: small on the right, medium in the middle, and large on the left. A block in the small slot is worth one, in the medium slot ten, and in the large slot one hundred. The same block changes value just by moving to a different slot on the tray.
Explaining place value by grade level
Write the number 111. Each 1 sits in a new spot. The first 1 means one hundred. The next 1 means ten. The last 1 means just one. Same digit, but each spot gives it a new value.
