Preface

You already live online. You send messages, upload photos, log into accounts, and download apps every day. This textbook is about doing all of that safely, responsibly, and healthily. It is written for Grade 11 students in the Standards-Based Curriculum, matched exactly to the 30 daily lessons of Term 4.

Each chapter opens with an essential question and clear learning objectives, teaches the ideas through short readings, then puts them to work with an activity and review questions. Key terms sit beside the text so you can find them quickly, and a full glossary and answer key live at the back of the book.
