Two books that we use as a part of our family worship are Big Book Of Questions and Answers and Big Book Of Questions & Answers About Jesus. Dr. Ferguson is an amazing teacher, both his doctrinal teachings for adults as well as his teaching material for kids. We are currently using the Big Book of Q&A About Jesus nightly, and I like the way the material is broken down into a Scriptural study about an aspect of Jesus life, followed by a question to consider, an activity and closing prayer. Combined with hymns and Scripture reading, this makes for an excellent addition to daily family worship time. Highly recommended.
