Why Does the Decimal "Move?"

A main focus of fifth grade math standards is to understand how numbers change when you multiply and divide by powers of 10 or multiply by decimal unit fractions (1/10, 1/100, 1/1000. . . .).  I had created this short SCRATCH animation to teach this concept and was reminded of it today as I taught the students. I think it work wells, and please use it if you'd like with your fifth graders. Of course it's better learning if students SCRATCH their own animation to show the concept.
