The goal of every parent is to bring up their children so that they'll become happy, responsible adults. This includes teaching them about finances and credit so that they learn how to use credit responsibly and not have financial worries around credit card debt. With so much personal finance information available on the Internet, it's hard to find the best, most reliable sources to help you do so. Here are a few that make the grade:

Federal Deposit Insurance Corporation (FDIC)
The FDIC is commonly known as the government organization that insures the money in your bank account. However, this agency also has a vested interest in seeing that the citizens of the U.S. manage their money wisely. The FDIC publishes a regular consumer bulletin to provide people with money management tips. It also has a special guide for young adults called "Taking Control of Your Finances" that includes information on credit cards, how to use them and how to choose them. It also has a guide specifically for teenagers called "Start Smart: Money Management for Teens" that explains more about saving, investing and borrowing -- and how not to get in the hole when it comes to debt.

National Financial Educators Council
The National Financial Educators Council believes that financial literacy starts early and that parents can do a lot to help their kids learn about personal finances and how to manage them. They have programs for children ranging in age from pre-kindergarten through fifth grade and students in middle school, high school and college.

The Mint
This website is the result of a partnership between the Northwestern Mutual Foundation and the National Council on Economic Education. The entire site is based around teaching children about money, and to that end it offers activities for kids and tweens. It also has a full section for parents to give handy pointers about passing along good fiscal responsibility, and there's a section for educators with ideas on various money management topics, including a lesson on credit cards that uses an online test called "What is Your Credit Card IQ?" and another quiz called "I Paid How Much?" that teaches tweens how finance charges work.

Jump$tart Coalition for Personal Financial Literacy
While Jump$tart has many resources available on its website, one of the nicer publications on its site is the "National Standards in K-12 Personal Finance Education." This lays out several personal finance concepts including credit and debt and states what children at a 4th grade, 8th grade and high school graduate level should know. Having access to this resource gives parents an idea of what their children can understand at different ages, and they can help teach concepts at a level their children can comprehend. The guide also comes with a financial glossary to help explain these topics.

It All Adds Up
Developed by the Council for Economic Education, this website features ways for teens to understand money, saving, investing, buying a car and credit cards. In the credit card module, teens will learn about credit ratings and how to build up a good rating. The site also introduces them to credit card debt and what happens when you carry a balance from month to month.

PBS: Electric Money
This website from PBS explores money and its transition to an electronic environment. One segment of the site called e-Money Revolution delves into different financial topics, including payments and credit cards. "What are Credit Cards?" explains their history, their function and how credit cards differ from debit cards. The site also contains a number of teaching guides, including one called "How Credit Cards Work," which teaches teens the basics of plastic and how the credit card system works.
