I have been working with a 2nd grade teacher during writing workshop, and most of her students are in the revision stage. Rather than starting by teaching her students ways that writers revise, we spent one workshop teaching them what it means to revise and what types of revision tools writers use (flaps, post-its, carrots, colored pencils, etc.) Once the students understood what revision was and made some of their own choices for how to revise their writing, we then began teaching them various strategies that writers use to revise. It has been amazing to watch the students understanding of revision evolve and even more amazing how much stronger their writing has become in such a short span of time!
Here are a few charts that we used to support the revision work in her classroom:
