Shared writing can be used across all grades.  Its structure is more supportive than modeled writing for middle and high school writers because it is based on shared experiences and teachers scribe the piece. Teacher and students work together to plan and co-create the content within 5-10 minutes of the 40-minute ELA period.  Shared writing supports and immerses writers in the structure, volume and development of various genres, preparing them for writing work that they will take on later independently in their own writing, possibly during writing workshop.
