This is one of the COOLEST websites I've ever found for teaching Spanish country and capital geography!!!!
It allows the kids a tactile way of dragging the countries to their respective locations on an interactive map. They can quiz themselves with a built-in "quiz tool" and shoot for 100% accuracy.
Not only does the website have countries and capitals, it also has the U.S. state and capitals. It's just a great way to learn about world geography.
The download will offer specific instructions you can print-off for your students.
