Hi @delilah.heil,
I responded to your post in the Discoveries forum here. Hope I gave you some ideas.
Discoveries meets these standards. For me in Colorado it meets the CTE pathway for CS Foundations. Principles meets the AP Standards for CS Principles. There are similar outcomes in the programming units but for me, Discoveries is the first class on my pathway but I allow students to enter my pathway at Principles.
Hope that helps,
Michelle
