My 11-year-old son won some money in a math contest at school. He doesn't have anything that he is interested in spending his money on immediately, and I suggested that instead of spending it just for the sake of spending it, he might consider buying stocks and building a little portfolio. He seemed interested in this idea, but I wasn't sure where he should start. He has around $150. Can you help us decide where to start? Thanks! Michelle, South Jordan, UT
