If the Moon rotates then we should see the dark side right? But as far as I know the Moon only shows one side to Earth, how can this be if it is rotating?

The rotation of the moon is in synch with its orbit around earth in such a way as to always face earth with the same side. This phenomenon is called tidal locking. The side facing away from earth is usually called the far side of the moon. It was photographed by Soviet spacecrafts in the 50s and 60s and later observed directly by the crews of a few of the Apollo missions. More details here.
