Take your students back to the "old days" of baseball cards by having them create a trading card for each of the Roman gods and goddesses. A picture can go on the front, either drawn by hand or printed and glued on from the Internet. On the back, such items as ancestry, famous deeds, property that they are the god or goddess of and special powers inform the reader about this particular deity. Making these cards can help students recall information about each character.
Several board games available on the market feature the conflicts among the gods and goddesses as a theme. "Hera and Zeus" is just one of these; while playing this game, players use various cards to attack mortals that Hera and Zeus are trying to favor, and the player with the most successful attacks ends up winning.
