Archimedes’ Puzzle

http://illuminations.nctm.org/Lesson.aspx?id=2523

“The Stomachion is an ancient tangram-type puzzle. Believed by some to have been created by Archimedes, it consists of 14 pieces cut from a square. The pieces can be rearranged to form other interesting shapes. In this lesson, students learn about the history of the Stomachion, use the pieces to create other figures, learn about symmetry and transformations, and investigate the areas of the pieces.”

I really like the area questions.

Has an Activity Sheet.
