The complete Unit 2, all 6 lessons
This computer science unit teaches the jobs an operating system does, how the kinds of systems differ and how to keep a system safe. Students trace app requests to the hardware, compare desktop, mobile, server and built-in systems and learn how using a computer changed over time.

All 6 lessons follow the same folder system, so you learn the layout once and teach the whole unit.
Real pages from Unit 2, the same clean design in every lesson.
Students fill in the blanks during the slides, with the word bank right on the page.
Students pick systems for users, advise a tutoring center on open source and answer a help desk ticket about malware.
The bonus folder has a review lesson, the unit test and a Form B retake, each with a Google Form and a key.
Each lesson has one editable deck. Every day starts at its own Day slide, and the speaker notes say what to say.

This unit is also part of the complete Computer Science Fundamentals course: all 8 units plus the Course-Wide Bonus folder.
They pick systems for users, advise a tutoring center on open source and answer a help desk ticket about malware, with a reason for each choice.
Students learn that any system can get malware, and that updates and safe habits protect every system.
Every page is a print-ready PDF, and the Google Forms™ and Google Slides™ let you teach the same unit in Google Classroom™.
Each day's plan is timed activity by activity against real reading and writing speeds.
Reviews help me a lot, and they help other teachers pick the right resources for their classes. It takes about a minute.
