Making a contract for safe online behaviorJust as you would teach a preschooler how to cross the street and a teenager how to drive, children need guidance on navigating the online world safely and responsibly.

After all, the potential consequences of reckless behavior can be just as damaging to a child's reputation, mental or physical health, or future life opportunities. Creating a family contract that defines the expectation and rules of online and technology use is a good place to start.

Stephen Balkam, chief executive officer of the Family Online Safety Institute, says such a document should be a conversation starter.

"As early as your kids can read and write" is when you should formalize the lessons about being a responsible digital citizen, he said.

"We're giving younger and younger children more powerful mobile devices," Balkam said. A contract gives them a way to begin to negotiate this digital world.

We examined various models of contracts online and have compiled a sample document for a young child and a teenager. Each is a starting point and can be amended to suit your family's needs.

The start of the school year is chance to review and gather everyone's signatures. Keep the contract handy, in a visible place near the computers in the home.
