This is a simple peer revision and editing activity that I use will my high school ELA classes. Students use a variety of colors to code the suggestions that they make on another student's paper. I provide a suggested list of questions that I go through one at a time in class, stopping to give students time to read and then provide feedback. This activity has gotten my students to be more skilled at providing specific feedback on each other's papers. As always, I provide you with an editable document so that you can changes for your own classroom as needed.
