The purpose of this article is to offer preschool teachers strategies for preventing challenging behavior and supporting the development of social skills and emotional competencies. This article is framed in a question and answer format using questions from teachers who the authors have worked with in the past. These questions and strategies are organized around the four levels of the Teaching Pyramid: (1) developing nurturing and responsive relationships; (2) designing social and physical environments to support children's social emotional development and prevent challenging behavior; (3) teaching social skills and promoting emotional competencies; and (4) designing individualized interventions for children with ongoing challenging behavior. Implementing the practices associated with only a single level of the Teaching Pyramid is not likely to effectively address the range of challenging behaviors found in many early childhood classrooms; rather, it is the comprehensive, intentional implementation of all levels of the Teaching Pyramid that is needed to effectively address challenging behavior.
