Teachers searching for high-quality educational content about investing for their middle or high school classrooms can turn to this new resource from the Alliance for Investor Education (AIE), which has highlighted what is considers 10 of the best investor education resources available for teachers and students. “InvestorEd 101: Best Classroom Tools” is a new section of the AIE’s web site that features resources from organizations such as National Endowment for Financial Education, the National Council on Economic Education, and the New York Stock Exchange. For example, in the Securities Industry and Financial Markets Association’s Stock Market Game, students start with a virtual cash account of $100,000 and strive to create the best-performing portfolio using a live online trading simulation. They work together in teams, practicing leadership, organization, negotiation, and cooperation as they compete for the top spot. In building a portfolio, students research and evaluate stocks and make decisions based on what they’ve learned. To determine why certain stocks perform the way they do, or why the broader market has moved up or down, they need to understand how the economy works. And to calculate their returns, they need to do the math.
