Traditional, Command, and market systems. Mixed economies, embargos, tariffs, etc. All words economics for 6th and 7th grade in Georgia (and possibly other states). I like to go over this PowerPoint and then let it scroll throughout the day.
students fill in the missing information such as "who decides what to produce" for each country. Fits into the Georgia 6th grade social studies standards. Great for any grade studying economic systems in Europe and the world.
