Different theater groups and drama classes have different themes. A drama youth group may choose a story or stories with religious meaning, such as Torah portions or Jesus' parables. Another group may want to dramatize specific historical events. Another group may choose to put their own take on a specific culture's folk tales. Regardless of whether you are teaching drama after school or at themed camp, you must be prepared for this day.
Your students will know ahead of time that this day is coming because you will have told them! You, the teacher, must have a collection of appropriate stories handy to consider with your students, or if not, a field trip to the library to find the type of story they are looking for.
Once the story or group of shorter tales is chosen, the real fun and work begins.
