I love to use Rainbow editing in my classroom. I used it in my first grade classroom to teach the process of writing. It is great to use in your writing center. This poster is an easy print out to hang in the classroom or put in your students writing folders.
I also have a miniature version that is great for your students to keep in their desk to refer to when writing.
Make sure when you are teaching Rainbow writing to explicitly teach each piece so that your student does not get confused!
If you use this in your classroom please let me know and give me feedback! I would love to know what worked for you and what does not!
