This study aimed to explore the issues and tasks in selecting educational content for the “Common Korean Language of South & North.” I considered three “capacities” which will be the directions of the common Korean language in the United Nation. Theses are the creativity capacity, the peace capacity, and the intercultural capacity. I suggested the unity capacity as the means to ease the cultural collisions between the south and the north. The tasks that we must carry out to develop the common curricula include the following: organizing the four capacities in the curriculum of common Korean language; selecting the themes of children’s literature; uniting the terms of the children’s literature and literature education; and developing the contents of literature education.
