This is a file containing a place value mat for hundreds, tens, and ones. It will need to be printed on legal size paper. I also have a file for sale that contains a place value mat for two digit numbers and the number tents shown in the preview image. As you can see in the preview picture, I chose to color code mine. This is completely optional, white paper would work just as well. Students form two or three digit numbers by placing the largest number at the bottom and smaller numbers on top so only one digit of each number shows. They can then separate them to show expanded form.
