6. What does a domino look like? The top of the domino is the numerator The bottom is the denominator and The horizontal line is one long fraction bar (division)

7. Steps for Dominoes 1) In the first “domino” put in the amount and unit(s) that are going to be converted over the number 1. NOTE: all “per” units go on the bottom (Ex. meters per second (m/s) meters goes on top and seconds goes on the bottom)

8. Steps for Dominoes 2) In the following dominoes: the conversion factor for the units metric units prefix unit to base unit or base unit to prefix unit NOTE: the top and bottom of the domino should be equivalent (the same amount or equal)

9. Steps for Dominoes 3) If the unit, you are working with, is on top then the “domino” unit needs to go on the bottom If the unit, you are working with, is on bottom then the “domino” unit needs to go on the top

10. Steps for Dominoes 4) For metric dominoes: The “multiplier” goes with the BASE unit, and “1” goes with the PREFIX unit

11. Steps for Dominoes 5) Calculate the domino by multiplying everything on the top and dividing everything on the bottom.
