Purpose: Students will learn how to use bits to encode a photographic image.

Vocabulary: Pixel, Metadata

Handout: “Invent a B&W Encoding Scheme”
Note: White = 1 & Black = 0

1. Share commonalities or patterns they see.
   • How have you encoded white and black portions of your image, what do 0 and 1 stand for in your encoding?
   • Are your encodings flexible enough to accommodate images of any size? * How do they accomplish this?
   • Is your encoding intuitive and easy to use?
   • Is your encoding efficient?
