The Internet

This page is being built as needed. If you notice something missing, or you are confused by something on the page, please inform your teacher or post something to the PARKING LOT.

Introduction

The bulk of this unit is based on Unit 2: The Internet from the Code.org AP Computer Science Principles curriculum. Since many of the activities are classroom activities, unplugged activities (no technology involved), or small group activities you will not follow the Code.org website in the same way you will for some of the later Units.

Use this page as a guide to work your way through this unit. Some activities will be done independently and some will be done in small groups. It is likely that we will jump around quite a bit and go back-and-forth between lessons as we go.

Pay close attention to the directions in the Daily Class Announcements so that you know what you need to be working on each day.

The Chapter and/or Lesson names below match what you see in Code.org to make it easier to stay on track.
