For people with Asperger's syndrome, any unexpected change in routine can be upsetting. Examples of routines used by Asperger's children include: an insistence on following an identical route to school each day; a lengthy bed-time ritual; or the repetition of a sequence of odd bodily movements. Also see Repetitive Activity / Behavior.
In an educational context, regular events during the day that have a familiar organisational and temporal pattern, and that are used as a context for learning; e.g. mealtime, quiet activities or story reading.
