In one of my past church positions,* we used the Rotation Model to teach the lesson portion of our Wednesday Night "Logos" program.

We rotated between Bible Games, Video, Music, and Art as our workshops and did two each Wednesday night: one for the younger kids and one for the older kids.  

It was easy, and was a great way to recruit parents in advance. I'd hand them a video or art project a week or two in advance, along some written notes and suggestions, and ask them to prepare a 20 to 30 minute lesson on it. I also taught some of the lessons. We didn't have the "workshop" rooms (yet), so we just used the fellowship hall space and classrooms as needed.

Sometimes the fellowship game became the Bible Game (workshop).  We also had a worship time with music, prayer, and quick message. We sometimes did that worship time as one of the workshops by adding more of a lesson component to the worship time (drama/skits, for example).

 Sneaky sneaky  
When the idea of using Rotation was brought up to the Sunday School people, many of them were already familiar with it as "the way we taught on Wednesday nights." When the Sunday School jumped on board, we converted their rooms to workshops. Also installed a computer lab  and kept on using the new workshops on Wednesday night as well as Sunday morning. Kids didn't grow tired of it.

*re: "position"
I was the volunteer Parish Associate" in that church who at the time only helped with Wed Night. When Sunday morning converted to Rotation and as our numbers grew on both Sun and Wed, the church decided to hire a part-time Christian educator!  (I was full-time into my software ministry in those days.)  That educator became a fan of Rotation and is still a member of Rotation.org today
