The 6th grade has been studying ancient Greece in our Ancient Civilizations class. We split into groups and each group researched a different element of ancient Greek society. The 5 elements we studied were Philosophy, Government, Architecture, Sports, and Mythology. Groups did individual written assignments, then combined their information. They constructed tri-fold boards with their information, graphic elements and examples, and other interesting facts about ancient Greece. They used the boards to make a presentation to the class and "teach" their element of Greek society to everyone else in the class.
Aside from the academic nature of the assignment, students were able to practice other skills as well. Time management was an element of this project, as was teamwork, listening, and public speaking.
My kids did an excellent job of "teaching" each other. I'm very proud of their effort!
