Curriculum Choice: Bible Study Decisions

We've participated in a Community Bible Study for four years now. I've relished the fellowship with other moms, women of faith and kids.  I really know the value of well-written study questions.  I enjoy studying the same Bible chapters that my kids are reading and studying each week.

Our CBS teaching leader's graphic last week to teach about Philippians 1.

As we move forward, I'm torn between continuing with the kids in a lower level study (for their ages and knowledge) and the alternatives. But, what are those alternatives?  I'm anxious to know more about what's available beyond.  Yet another question to answer in prayer and the next homeschool conference (GHC-CVG).
