Hi, Jimmy! Welcome to Rotation.org! Thank you for registering as a member. 
You can find an overview of the Workshop Rotation Model here.
And here is more information on scheduling lessons.
The wonderful thing about the lessons that you will find at our site is that they are very adaptable to individual churches' needs. We are finding that more and more churches are shortening the time available for Sunday school. So we are creating lessons that can be taught in 30-45 minutes. But we also include adaptations for churches such as yours who have more time - additional games or more detailed art projects or more run-throughs of dramas, for example.
Also, churches who have a longer time often open with a group time for singing/prayer/worship before the students go to their different age-level classes.
Take a look at the resources i linked, and then tell us a bit more about your situation (such as the number of students and classrooms, the format you are currently using) and we can help you figure out what will work for your community.
