A simple way to change up a lesson is to do it in a 360 degree method. Here is how I do it. I first set all of the chairs apart a bit so that they can easily be turned to face any direction. Sometimes I will bring in a swivel office chair and give it to some lucky class member. My notes are on a podium in one corner, my Bible is in another corner, a white board and marker is in another corner, and any object is in another corner. During the entire lesson, I am going from one corner of the room to another back and forth and asking everyone to shift their chairs and face me as I keep talking.
