The purpose of this article is to provide tools for preschool professionals to plan for transitions between daily routines, to identify challenging transitions during the day, and to offer strategies to support transitions in classrooms to prevent challenging behaviors from occurring due to frequent changes. Specifically, the authors answer three questions early childhood educators frequently ask: (a) Why should I worry about transitions? (b) What tools can I use to plan effective transitions? and (c) What specific support and strategies can I use to facilitate transitions between daily routines? (Contains 2 figures and 1 table.)
