Now that you have a solid understanding of the relative locations of each region, let's see how you do with Border Patrol. For each region there is a separate pdf with some outlined countries on them.
First- Identify the country that is completely outlined
Second- Draw out the bordering countries (you might want to make them a little smaller than is correct, in order to save space for the others
Third- If you would like to push yourself, add in the physical features and landmarks that are in the region
Fourth- Check your work against an atlas
If you can do this successfully, then we can certainly say that you have a mastery of the location of the countries in each region.
Southwest and South Asia
Southeast and East Asia
