This case study of a first grade teacher enacting a social action curriculum is based on the understanding that schools can be sites where even young children can work toward the common good. This paper examines the way a first grade teacher (Paula Rogovin) and her students built solidarity with a community member and in turn adopted a new social concern as their own. We identify, detail, and analyze the building of ties of solidarity as a practice enacted within a social action curriculum. (Contains 1 note.)
