I need help fleshing out an idea. I was wondering if a trivum model could be applied to a Sunday School program. I was thinking of applying the WTM history approach to the Bible, and going through the entire text over a 3 or 4 year period. Each time we would teach at a developmentally appropriate level. For example 1st - 4th grade we would just teach the stories. From 5th to 8th grades we can start to read more analytically, picking apart the scripture and looking for connections, types, and parallels. The high school years we could spend on things like apologetics. Do you think this could work? Can you offer any books or curriculum ideas that will accomplish my goals at each level?
