Computer Science Discoveries Unit 5 Chapter 1 Lesson 3: ASCII and Binary Representation (18-19)

Subject Area

Digital Literacy and Computer Science

Grade(s)

6

Overview

This lesson introduces a formal binary system for encoding information, the ASCII system for representing letters and other characters. At the beginning of the lesson, the teacher introduces the fact that computers must represent information using either "on" or "off". The class is then introduced to the ASCII system for representing text using binary symbols and practices using this system before encoding their own messages using ASCII.
