This paper aims to propose the teaching contents of early childhood education for junior high school teachers in their home economics class. The contents presently taught by over 90% of teachers are related to children's physical and mental development as well as their life. Meanwhile, the contents, which teachers consider necessary but not included in their lessons, are the area related to the efforts to provide children with the environment required for playing as well as their growth and development. Such being the case, this paper proposes the teaching contents for teachers to have their students learn about the following set of three items: Children's Growth & Development, Children's Life, and Role of Family in promoting the first and second items. At the same time, students are guided to give thought, as a member of the society, on how the children's environment should be.
