These four anchor papers are pictured in a post on my blog, Creating Readers and Writers
By request, I've included them here in this download along with the other pieces needed to make the writing rubric shown in the post.
You can read more about the specific lesson and the goal for the students' collaborative discussion at this post:
Studying Anchor Papers for Writing
This lesson will work in any K-2 classroom, although you may need to create your own writing samples depending on your students' levels and needs. An additional blank writing template has been included in case you choose to design your own.
