In this activity students use place value mats at their desks to discover what happens when they multiply or divide by powers of ten. I have created this so that students have to manipulate the numbers and analyze each move through a series of guided questions. They actually get to see what is happening to the place value of the numbers! I created this because I had many students struggling with this concept and refused to give up! After this activity, students were so excited because they got to see what they were doing when they multiply or divide and understood!
