Data Representation: Millions of Colors

Lesson Focus 
Display devices on cellphones, tablets and computers of all sizes, use bits of information to represent color. By first creating, and then playing a card game, students learn how additive color is represented as binary and hexadecimal numbers. They will also get practice in recognizing and manipulating binary and hexadecimal representations.

Age Levels:

14 - 17
Objectives

  • number systems used in computing: binary, hexadecimal.
  • how color is displayed on digital devices.
  • how and why additive color is represented as a single number.
  • why there are millions of colors available on mobile devices and computer screens.

 

Anticipated Learner Outcomes 
Students will demonstrate/explain:
  • how information is stored in binary, and represented in hexadecimal form.
  • how additive color is represented in binary and hexadecimal.
  • how to add and subtract hexadecimal numbers.
