With the 2008 Summer Olympics in full swing for the next few weeks, there are some fun money lessons for kids.
For younger kids: Introduce the concept of different currencies in different countries. Explain that travels to foreign countries will require the use of a different kind of money. If you have any foreign coins, let your children compare the size, color, and pictures to the coins in their piggy bank.
For older kids: Introduce exchange rates during the Olympics. As you watch different competitors, determine the amount of currency your child will get in the athlete's country for one dollar.
