There are many Thinking Routines, and the list is not exclusive. Teachers, researchers and learners are developing new routines, and combining routines to achieve deeper understanding. For example, within any thinking routine, the facilitator may interject, "What makes you say that?", which is a thinking routine in and of itself.
Teachers are encouraged not to treat thinking routines as lesson plans, but to use thinking routines within their existing plans. It is a means to an end, a process.
One of the key principles of Making Thinking Visible is just that: make the learner's thinking visible to them. Thinking routines are a metacognitive process, and a process of documentation and reflection. This will also aid in the development of a thinking culture within the classroom.
The Artful Thinking Palatte places sample thinking routines under thinking dispositional goals:
Questioning & Investigating
Observing & Describing
Comparing & Connecting
