You want a good class structure? I have one. I would say start with a warm up generally. Stretching of the back, arms, and legs. Do some squats, some push ups, rollercoasters, etc. While people are doing that, tell them about history, the founders, etc. for the first few days. Then, yeah, work on rolls and such. If people laugh at you during any point, have them demonstrate to the best of their abilities. Do not mock them if they can't do it, but tell them what they could do better. Have the who class drill, then progress. After your class is done, the cooldown works really well. I can see SFPK uses it, and RVPK uses it as well. All in all, it should be pretty structured.
Also, for a documentary, Point B. Best one I've seen.
