A family newspaper can be typed up on the computer or you can use it as writing practice for younger kids, then glue the whole thing together. You probably have the supplies at home.
Start out by teaching your kids the basics of creating a story for a family newspaper. You can have each person interview someone else in the family. Help younger kids come up with a topic and questions to ask. Questions such as “What does Mommy do?” or “What is (child)’s favorite activity?” can be a lot of fun.
If you work it up on the computer you can even print it out or send it by email to grandparents and other relatives who might get a kick out of seeing what everyone is up to.
