The Debt Quake in the Eurozone
This static image is simple, well designed and focuses on one key issue, public debt as a percentage of GDP in 2000 and 2010.
You could use this type of image as the backbone for a lecture, or series of lectures. It could also be the starting point for a range of problems and exercises.
Mint.com also has an education page. It’s aimed at secondary students but the structure of the lesson plans is worth a look.
