Here is a worksheet that I used extensively to help students learn how to use the factor label method (or dimensional analysis).
It can be used for non-chemistry unit conversions.
It is a great scaffolding worksheet. And students love the shapes. I used this in conjunction with the mneumonic "Got Cravings For Skipping."
"Got" stands for the "Given" of the problem, "Cravings For" stands for the appropriate "Conversion Factor(s)" and "Skipping" stands for "Solving" at the end.
