This is a visual representation of metric conversions that makes it easier for kids to remember and apply! As I was teaching metric conversions, I started referring to the new units as going to "kilo's" house or milli's house and we would move our decimal up or down the street. This helped kids internalize it a lot better. I hope this helps you teach students metric conversions!
