Rubik's Cube: Twisted Corner

Image of Rubik's Cube with twisted corner.

In the "Games and Puzzles" book, students explore the mathematics of the Rubik's Cube. This image shows one particularly frustrating situation: the red-white-green corner cube is exactly in the location where we want it, except the faces point into the wrong direction. How can we get the faces to all point in the wanted direction, ideally without messing up any of the other nice white, red, and green cubies?
