Hello Karen,
I have developed a curriculum that is being used across the nation that is being used with 6-12 graders. It is research based and is 12 hours long. Here is a link to my web page. If you would like a 15 day digital preview copy please email me at carolynrichcurtis@gmail. I am available for assistance.
