How I Use It
I would use this as a simple introduction to The Great Depression just to get students interested. I would NOT use it further in lessons because it doesn't offer much clarity and it is short.
Overall again it would be useful for an introduction but not for more detailed instruction. It would be interesting for students to play around with in small groups but after that short activity you should begin a much more clear and detailed lesson. Possibly even discuss the unclarities in the simulations.
