This document provides ideas and instructions for classroom activities using Raspberry Pi computers. It suggests starting with having students label a picture of a computer's internal parts to understand what is inside. Several activity ideas are then listed, such as programming a MP3 player interface or Scratch, creating an arcade cabinet emulator, or designing a kiosk for a school reception area. Guidelines are also given for setting up the Raspberry Pis, like preparing SD cards with different operating systems to compare.
