Sonlight is a structured, literature-based learning program that provides an instructor’s guide, which allows flexibility for a parent-directed education program. Each core program weaves together a year's worth of history and geography, literature, and language arts. Sonlight offers several math curriculum options as well as corresponding manipulatives. This is a great program for teaching multiple age groups, K-12. Teaching materials are faith-based, so check with your Advisory Teacher before selecting this curriculum.
