I teach it like this:
Roll your dice
Line up all of them under the matching icons.
Wild dice { * } can be used under any column.
These are your workers.
NOW chose one worker of any type to activate one action. It's type does not have to match the icon on the action.
Finally you can reassign any workers by discarding dice to the dictate function. Effectively giving up a dice to use another dice as any worker you want. (The dice you give up goes back in the cup at the end of the round)
