I went to a Code.org training session at the NC State Institute. At that training, they demonstrated a PowerPoint presentation that could be used for teaching each lesson. Are these presentations still available?
The slides for each unit in Computer Science Discoveries are available in the lesson plans. To obtain access to the lesson plans, become a verified teacher (the information for doing that is on this page). Once you are a verified teacher, you can view the lesson plans by clicking on each unit from this course overview page. In addition to the slides, the lesson plans are full of resources and tips for teaching each lesson so it is well worth becoming a verified teacher !
Happy New Year,
