Lesson 19: Binary Images with Artist

Binary | Artist

Overview

This series of online lessons will have students learning to make images using on and off.

Purpose

This will help reinforce the fact that computers can do a multitude of things with 0s and 1s.

Objectives

Students will be able to:

  • Create pictures using unique combinations of on and off
  • Identify repeated sequences and break long codes up into smaller chunks that can be looped
  • Utilize loops and binary code to recreate provided images

Warm Up (15)

To begin, it can be helpful to review the previous lesson, specifically different ways of using binary to indicate how to create an image on a grid. This stage will translate the unplugged activity into a simple, independent online lesson.

Not all of these images are intuitive. Encourage students to click "Run" to see what happens, even if their code isn't "finished" yet.

Journaling

Having students write about what they learned, why it’s useful, and how they feel about it can help solidify any knowledge they obtained today and build a review sheet for them to look to in the future.

Journal Prompts:

  • What was today’s lesson about?
  • How did you feel during today’s lesson?
  • Did you like drawing on the 8x8 grid or the 16x16 grid better? Why?
  • Computers also store sounds using binary. Use your imagination to write down a possible way for that to work.
