This is part of a series of posts about writing coaching cycles, which include examples from several disciplines.

During a coaching cycle, I was working with math teacher individually.  A trend I noticed was that teachers commented on how they were looking for a tool to help organize students’ thoughts. Together, a math teacher and I, created this graphic organizer.  Click here.

One part we got stuck on was that the writing is so individual depending on the math content.  So it is hard to make a common graphic organizer.  We are hoping this is a start.  What math writing tools do you have?  Share in the comments!
