Good recommendations here. I'll add that often the video and/or drama provide a good overview of the story, so I typically try to schedule those early in the rotation, especially for younger children. I tend to schedule the less "concrete" workshops later -- such as cooking and science. BUT... as has been mentioned, you really can do whatever works best for you and your teachers. And we always remind our teachers to be aware of how far into the rotation they are... and to adjust as needed -- basic story usually the first/second week and then more discussion/reflection/digging deeper by the 3/4th weeks.
Blessings on your ministry!
