The common core lessons are on Trudy Ludwig's Resource page: http://www.trudyludwig.com/resources_core.html
My Secret Bully: I highly recommend this book for girls in 4th-6th grade. I am currently using it for a fourth grade girl group. The story is about two girls who are "friends". One of the girls, Katie, talks about the other behind her back and begins excluding her from activities. Katie begins suffering from stomach problems and her mother provides advice/coping skills for Katie to use. There are some discussion questions at the end of the book as well. You can find more lesson connections HERE, HERE, and HERE.
Sorry!: I am currently using this book in my fourth grade classroom guidance lessons. The story line explains that saying sorry doesn't cut it, especially when you have done something mean on purpose. I love that the teacher prompts the character to "make it right" to show that they are truly sorry. Here is another lesson that you can use with this book: https://www.researchpress.com/sites/default/files/books/addContent/4986A.pdf
Confessions of a Former Bully: Confessions of a Former Bully is a follow up to My Secret Bully. This time Katie gets caught teasing a schoolmate and meets with the school counselor to learn how to be a better friend. This book is full of tips for dealing with bullying as well as ways to turn bully behavior around. I love the fact that the school counselor is involved!!!

The Invisible Boy: This is a good book for elementary students. I am currently using it with a small group of second grade boys. The story is about a student, Brian, who is isolated/excluded by his peers. Brian imagines what it would be like to be a part of the group and the artwork in this story leads to its own discussion. The story includes discussion questions as well. You can find more lessons HERE, HERE and HERE.
Gifts from the Enemy: I don't own this book but I am going to include it anyway because it looks like it could be a good one. I just added it to my amazon shopping cart and plan to order it later today. After reading the book description, it sounds like a book that would be great for a Junior High classroom lesson following a Social Studies lesson on the Holocaust.
Just Kidding: I don't have a common core lesson linked to this book but it is still a good book to use. If you need another lesson (other than the one on Trudy Ludwig's page) I have used the one shared Here by Coffee Cups & Lesson Plans.
