This one-page sheet outlines all of the things that happen on a player's turn when playing the Carcassonne Big Box (2008 edition) with all of the expansions in play.

The first time my family played with all of the expansions at once, it was easy for the kids to forget all of their options, or for us adults to forget the "order of operations", so I printed this up to have handy as a reminder. (And it's still useful even if you're not playing every expansion...)
