The Stonehenge game is a working model of the real monolith. The site cards indicate locations of henges from the Orkney Islands to the south of England, and includes Ireland, Scotland, and Wales. Like the late Neolithic original, the Stonehenge game is a computer for the Sun - Earth - Moon orbits required to predict the eclipses of the Sun and Moon. The game incorporates the phases of the Moon, the Solstices, and both Equinoxes. —description from the publisher Game participation will reinforce knowledge of astronomy, math, geography, and history.
