If you're looking for a fun (and easy!) way to learn the names of all the countries in the world, I highly, highly suggest checking into Kathy Troxel's Geography Songs. Wow! They are all fantastic! We have the book that goes with it, but Balancing Everything has made coloring maps that go with the individual songs about Africa. Yay!
I know that Africa is studied is Cycle 1, but print these babies out, file 'em, and you'll have them ready to go in a couple of years. Or, you could tackle this as a summer project!
Speaking of summer projects, I think we're going to start blobbing the world soon using Brandy's maps at Half-a-Hundred Acre Wood. Do you have any fun summer ideas in the works?
