This 2 week unit plan for Mockingbird by Kathryn Erskine is a great novel for any young adult. It is geared specifically toward 5th grade students. I taught this to the highest reading group in 5th grade, so it could easily transfer to a 6th grade classroom as well.
This is a great book about empathy and acceptance as it deals with a student that has Autism.
Some activities that are included in the unit plan are: Letters to the Author, an Empathy Project, Character studies, cover re-designs, and much more! Assessments are also included with an accompanying answer key.
There is a student journal that accompanies this unit plan as well which can also be found in my store.
