Are you looking for adult or children's classes? Mixed ages or one class per level?
I ask, bc in another thread it appeared you were dealing with a very small and unpredictable number of people-- and this is posted in the house church subforum. In a case like that, it seems more effective to reflect on a topic through the week, organize supporting scriptures, and then open it up for discussion in class.
Most people have something to offer -- whether it's scriptural knowledge, prayer experience, learning from life tragedies, kindness and peacemaking, teaching skills, visual presentation skills, analytical synthesis of ideas, ancient language skills, enthusiasm, curiosity... these will blend together to make an effective sharing of information.
It doesn't need to be all on your shoulders, if you allow yourself to facilitate a meaningful conversation. Get the ball rolling, keep it on track, and slow down momentum at the end.
