There are six books in the upper level Bible Truths series for junior and senior high students. It's best to start with the first book in the series, regardless of age, because of the sequence of the study. However, book F could easily be used on its own since it reviews basic questions on the nature of God, creation, the Fall, redemption, and our relationship with God before moving on to practical Christian living.
These worktexts are excellent and could even be used without Teacher's Editions. But Teacher's Editions are helpful, and offer much additional material for teaching and discussion. The third editions include a Teacher's Tooklit CD-ROM in the back of the TE that has extras such as Scripture exercises and their corresponding answer keys. If you skip the TEs, there is still plenty of material to work with in student worktexts.
Most lessons open with a story to illustrate the theme, then study the Scripture from which the lesson is drawn. Memory work is included. Content is solid, working on both building a body of knowledge and relationship with God. Student worktexts are printed in full color and are written with lots of stories and applications that are likely to keep teens engaged.
Homeschool kits for each level include the TE, student worktext, test packet, and tests answer key.
