Project Zero’s Thinking Routines Toolbox, developed by Harvard University, makes extensive use of learning routines that are thinking rich. A routine can be thought of as any procedure, process, or pattern of action that is used repeatedly to manage and facilitate the accomplishment of specific goals or tasks. These routines are simple structures, for example a set of questions or a short sequence of steps, that can be used across various grade levels and content. What makes them routines, versus merely strategies, is that they get used over and over again in the learning space so that they become part of the learning culture. The routines become the ways in which students go about the process of learning and can be used in conjunction with particular learning space configurations.
