Two games for introducing population-related concepts and understandings into the junior-senior high school curriculum are described in this document. Planafam I is a card game which utilizes role-play techniques. A primary purpose is to increase the student's personal awareness of social norms and biological constraints in fertility behavior. Players trace the entire reproductive lifespan of a couple from rural India, making decisions which influence their family size and composition. The teacher functions as a roving provoker of discussion, asking questions, keeping students within the framework of Indian culture, etc. Materials required are: a large piece of paper or cardboard; a marking pen; three decks of ordinary playing cards. Planafam II is a role-play simulation designed to help students and young adults span the gap between large scale and personal perspectives, and to facilitate consideration of factors involved in reproductive decision making at the personal/family level. The role player (part of a group numbering from 3-10) takes the role of a woman whose reproductive life provides the focus for the game. Materials needed are: a large piece of stiff white paper; three sets of double-six dominoes; two decks of playing cards; marking pens; and ordinary buttons. Complete instructions and suggestions for possible discussion are provided for the two games. (Author/JLB)
