A couple of my classes are currently participating in a large mock-economy exercise designed to simulate the economic climate of the 1880's through early 1900's in the United States. We have a "Rockefeller," a "Carnegie," and a "JP Morgan" character is starting to emerge. Prior to starting the activity, I showed a couple of Common Craft videos to the classes as reinforcement for the banking concepts that we have discussed. The class watched Borrowing Money in Plain English and Investing in Plain English. I have embedded Investing in Plain English below. If anyone is interested in a digital copy of directions and handouts for the mock economy exercise, send me an email at richardbyrne (at) freetech4teachers.com and I'll send it to you.
