Tangrams are Chinese puzzles consisting of 7 geometric pieces that are believed to be hundreds of years old, although the earliest records of these puzzles are from the 19th century. I remember my high school Geometry teacher introduced my class to this "Chinese Moving Puzzle," and I have loved it since."
