Can the “Visits To…” series be complete without “Material World” and “Hungry Planet”?
Material World and Hungry Planet are both required for some of the lessons. Each Visits to… book contains two kinds of lessons. In one type, your child fills in a blank map to learn the geography. In the other type, your child reads from Material World and Hungry Planet about modern families who live in some of the studied countries.
Every Visits to… book uses both of those resources, so if you use more than one Visit, you’ll be reusing those books.
