LIFEPAC is a Christian homeschool curriculum for grades K-12. Designed by a team of accomplished educators with years of classroom experience, LIFEPAC is based on the principle of mastery learning. Students master content in each unit worktext before progressing to the next. Ten LIFEPAC worktexts provide one full year of learning content per grade level; individual worktexts can also be used as supplemental material. In addition, you can mix and match subjects or grade level worktexts to personalize your student's curriculum content. Individual worktexts take approximately 3 to 4 weeks to complete.
