Managing money is a skill that children need to learn. From building a budget and balancing a checkbook to saving for retirement and making investments, eventually they'll need to start making their own money decisions. If your kids are starting to ask questions about the stock market, take advantage of their curiosity to teach them a little bit about finance. Start by making sure they have a well-funded savings account, suggests CNBC personal finance expert Carmen Wong Ulrich. Then, if they can afford to lose it, let them take a little bit of money to invest on their own. Index Funds and Exchange Traded Funds are great places for beginners to start. Online brokers like TDAmeritrade.com and ETrade.com can help them get started. Watch the video to see Carmen explain.
