What's inside

What does this lesson cover?

Many students think an intranet is the same as the Internet, or that any page people reach over the Internet must be public. This lesson uses a single business and its sites to show who can open each one and why. Students learn that workers and chosen outsiders still must log in, even when they reach a private site from far away.

Why teachers love this lesson

Every choice depends on who needs the information

Students decide what goes on the intranet, the extranet and the public website by asking who needs it and what must stay private.

Students fix someone else's mistakes

Correcting the manager's plan shows you whether students can spot private information in the wrong place.

Print and digital

Every page is a print-ready PDF, and the Google Forms™ and Google Slides™ let you teach the same lesson in Google Classroom™.

A key for every page

Every day has its own answer key, and every written question has a sample answer and what to look for.

Every day fits a 45-minute class

Each day's plan is timed activity by activity against real reading and writing speeds.

Written for your students

Every student page is checked for reading level, with plain words and complete sentences.
