The study guide is written for parents to work through with younger children and for older children to work through independently. It is printed separately from the book, allowing multiple students from the same family to write in their own copy at a fraction of the price. This lets each student record his or her own observations. Plus, if a parent or student wants to work through the book more than once, they only need to purchase another study guide. The study guide, along with The Gospel Made Clear to Children book, is the perfect resource for family discipleship, Sunday School curriculum, or homeschool co-op class.
