Teachers often ask me, "What are we expecting students to make as they write in this unit?" Sometimes we all need a vision of what is possible and so the Teachers College Reading and Writing Project (TCRWP) has put student samples from various units of study up on the Project's website.

Many TCRWP member schools also know about the narrative writing continuum on the website. Schools have used this helpful tool to describe student progress to parents as well as assess student writing and plan for units of study across grades in a school.
