Each book spans two age groups. Won’t the children know the topics after the first year?
Although many of the topics appear simple on the surface, their implications and application in daily life can be difficult to bring out in one session. These topics and concepts comprise the fundamental basis of religious, philosophical, and ethical thought throughout history. It would be unreasonable and unrealistic to expect that children will be able to immediately and completely absorb these topics including their vast implications after only one exposure.
