My daughter loves memorizing the locations of exotic countries around the world, and we go through a lot of map printables. It took me a long time to get a suitable collection, with the right level of detail, borders and graphic size.
So I packed them all together along with one of our handy geographic notebooking pages where you can do a country-by-country project. I think there are 7 maps (each continent and a world map) plus the notebooking template in this free printable set. The maps have national boundaries, except for USA, Canada and Australia that are broken down by province/state too.
