  Explain the many ways that bills can be paid: over the phone, paper or by check, electronic check or online check. Discuss how each method of bill pay takes money out of your account.

  Explain that credit cards are a loan and need to be repaid. Share how each month a credit card statement comes in the mail with a bill.
• Browsing the Internet
  While online, explain to your children how valuable their personal information and privacy is to you, to them and to online predators.
