In preparation for Paper 1 in May, students have to write A LOT of essays for practice. As teachers, we don't have time to grade and provide feedback for all of these lengthy essays. I use Writer's Workshop sessions to allow students to give each other effective feedback for improving their writing.
This particular PowerPoint is designed for a Paper 1 Commentary on a poetry option. I use some lingo in this presentation (interpretive sentences, commentary) but have also tried to explain what these ideas are in the PowerPoint as well. It normally takes the entire 50 minutes to complete this workshop if students are providing strong feedback. For block periods, you can have them trade papers 2-3 times if necessary.
I had my students revise their essays after reading through their feedback. I also had them go through the Paper 1 rubric before they rewrite. Then they turn it in for me to read and grade.
