The Puzzle Map of USA (G 080-1) features each state as an individual wooden piece with a lifting knob, scaled for use in the lower elementary environment where children are deepening their understanding of their own country's political geography. It works well alongside physical geography materials and state research booklets, and many guides find it bridges nicely between the continent maps and more advanced atlas work. A classroom set without this map leaves a noticeable gap for children ready to move from continental study into national and regional detail.
