This is a fun way for students to really get to know Greek (or Roman) gods and goddesses. I have used this with 9th graders for the odyssey, and my AP Lit students when studying archetypal characters: it could be used with many levels studying mythology. The project requires knowledge of the pedigree, character traits, specific story, and symbols of the assigned god or goddess.
I created this as a way for my students to research a god or goddess, create them as a puppet, then present them to the class. My students have always really enjoyed the research and have come up with the most creative puppets. I have a jar with god and goddess names they draw from. Typically the presentations take one to two class periods (depending on class size). I have given three days to one week (outside of class time) for completion.
This is a fun idea, but that is all it is. I would expect to see a fully developed assignment sheet with rubric and more specific guidelines. If you included a photo of some completed student projects that would be helpful as well.
