For logic, we are starting with Logic Safari and Analogies for Beginners. We are also still working through the last of the four Developing the Early Learner books. These books came with out Sonlight Core P 4/5 a while back. Note: I really like these books. They aren’t difficult. We just took our time, obviously, and treated them as extras. Our plan is to do a page or two out all these books every Friday.
