This brief discusses the confusion some young children feel in moving from one activity to another (e.g., bus to classroom, cubbies to book reading, art time to lunch) that often results in frustration and challenging behaviors. The paper provides practical information on a variety of strategies to help preschool children make smooth, independent transitions. Using a question and answer format, it addresses the following issues: (1) What are transitions between activities?; (2) Why is it important to address transitions between activities?; (3) Who are the children who have participated in research on transitions?; (4) Where do I find more information on implementing this practice?; and (5) What is the scientific basis for this practice? Examples of how specific practices might be used and a one page summary handout for practitioners and families are included. (SG)
