First, thank you for shopping our store. Lamp+Light Homeschool is a grass roots curriculum that offers a minimalist and Christian approach to homeschooling. Lamp+Light grew from many motherly calls to reform the homeschool parent mindset from a consumer, busy, "more" outlook; to an intentionally less mindset. Less stress, less planning, less worry, less pulling and stretching to force the materials to fit LIFE! Our focus is on low fuss lessons for families looking to find peace and meaning within their homeschool routines. Each curriculum contains lessons that range from Kindergarten; all the way through 12th grade. So that is one book for ALL your grade levels and subjects. The lessons are open ended so that either (teacher or student) can dive as deep or as shallow into a topic as they prefer.
