Students are given $10,000 (in pretend money, of course) to invest in any stock combination of their choice. This form allows students to document their investments so that they can easily calculate earnings at the end of the chosen time period. I allow my students to "buy" stocks at the beginning of the year and then calculate earnings at the end of the year by researching the changing value of their stocks over time. Provides an excellent learning opportunity by allowing students to use internet resources to research stock values. I give a prize to the student whose stocks have increased in value the most throughout the year.
