Dear Lori, sorry for taking so long to respond. I had a baby a few days before you emailed and have not been as connected to my computer.
I made everything for this unit, I have friends who work with the stock market and over the years have implemented some form of a stock market unit with students ranging from grades 3 to 7. This unit has been used with grades 6 and 7. This past year I did a more intensive 4 part unit with my honors class and it went very well. Let me know if you want more information.
