This is a project I use every year with my middle school World History Students. Students create a two part project: a biography and an original myth. I usually use this as a cross-curricular project with Language Arts classes. After the project, we have a god and goddess feast where students dress up as their god or goddess, bring food, and have a "feast" in character.
Your purchase includes directions for the project, a list of Greek gods with Roman counterparts, a Biography form for the students' god or goddess, and a grading sheet.
