There are a lot of different stock market games on the internet. The problem I have run into is I often only have very limited access to computers to use with my students. So I modified the stock market assignment where it can be done without the use of computers and internet.
This packet includes the PowerPoint presentations that I use with my students to introduce them to the stock market with a few key terms they should know along with a PPT that includes directions and examples of how to complete the assignment.
I also include the worksheets that I use in class for my students to create their own stock portfolio and to track/calculate their gains and losses. This lesson can be completed in 1-3 class periods or extended for a longer period of time.
