This is a great lesson to introduce the Command or Planned economy to students, whether this is a history or economics class.
I run an activity in this lesson that simulates the frustrations and overall inefficiency of this type of economic system.
Students learn what the system is about and its advantages and disadvantages.
There are several documents and a power point aid contained in this lesson, plus instructions on how to run the simulation. We have a great time with it year after year.
