This study aims to rethink how autonomy and coexistence should be acquired by students and family in the curriculum of home economics at three-year junior high school. Family plays an important role for us. However, "how we teach family in home economics" based on students' privacies has been called into question. Thus, Lessons in this study were carried out to make ninth-grade students think about themselves and their families based on "what they have learned so far and family" to connect with everything in terms of family mentioned in contents of home economics lessons. In lessons, students were asked to look back at themselves raised in educational continuity from kindergarten through early secondary levels and think about themselves in the future. Implications of results are discussed to propose effects of lessons on changes in students' perspectives toward family, explore ways of desirable teaching to foster children's coexistence and future directions of curriculum and material developments in home economics.
