The resource I would like to share is from Common Sense Education in the area of Cyberbulling.
https://www.commonsensemedia.org/educators/cyberbullying-toolkitI have focused on the Middle School level as this is a very difficult time for kids as they are going through the Jekell and Hyde part of their life... one minute they are an adult and the next a child. This resource does a very good job of teaching students how to deal and react to situations that every middle school student can relate to. Not only are there lesson plans, but also videos that help teach the topic.
