Children with ASD benefit from structure and order and may behave in very rigid patterns.. In addition they find disruptions in routine and changes to activities (i.e. transitions) and cooperative play to be difficult and for some, potentially stressful. When these changes in routine occur, students with ASD may become upset which, in turn, impacts their social interactions and learning.Their tendency to become preoccupied with unimportant routines or rituals may help to bring order to a world that is otherwise very confusing.
