The purpose in this paper is to develop the strategy and lesson plan for teaching elementary social studies to introduce a new view of society. We developed the unit plan "Considering maps, could you think what's a map" which is organized so that a student's view of map might be raised from a low level to a high level. We have prepared two views of map to plan the unit. One is a copy-theory of map, i. e., a view of map that a map copies reality. Another is a composition-theory of map, i. e., a view of map that a map is selected and constituted of portions and elements in reality. As students at fourth grade have a copy-theory in everylife, we have planed the social studies lesson that they acquire a new view of map, a composition-theory of map,and practiced the plan in the attached Mihara elementary school, Hiroshima University.
