For Grades 7 through adult, these two sets teach logic from a Christian perspective. The first set is Introductory Logic, followed by Intermediate Logic. Lessons have definitions of important terms, key points, and common errors, with exercises that teach logic skills. The teacher’s guide includes the lessons schedules and plans, answers, reviews, and quizzes and tests, as well as the student text content. A DVD set has lessons that coordinate with the student text. A test and quiz packet is also available for each level.
