Explorer’s Bible Study offers Bible instruction at three levels. Beginnings and Foundations is for ages 2-8, Discovery for grades 3-6, and Quest for Junior and Senior high school. Each level has several workbooks with various topics such as “Faith at Work” or “God’s Promises” and companion answer keys for each workbook. Workbooks have notes to the teacher, a plan of study, and then a series of lessons with questions and activities. Early grade books are more like lesson plans for the teacher, with the upper level books written directly to the student.
