After introducing the topics of Self Image and Identity, the discussion should be followed by the various factors that influence both out perception of self and how we present ourselves (i.e., age, sex, gender, religion, culture, social class, language(s) spoken, race, where you live, family, placement in family, personal interests, level of ability, appearance, friends, media, personality/temperament, …)
Start by brainstorming all the factors that students feel have an impact on who they are. Introduce any factors they may not have considered.
