Pixels and Possibilities · Lesson 1

Abstraction with Paper Pixels

Students learn what pixels are, connect pixel art to mosaics and pointillism, and create their own analog pixel artwork on graph paper.

Students explore how artists and computer scientists use abstraction to represent complex ideas with simple visual elements. They begin by learning what pixels are and how pixel art is created, comparing digital pixel art to artistic traditions such as mosaics and pointillism. Students create their own analog pixel artwork using graph paper before transitioning to Fractal Studio to recreate and modify pixel artwork digitally. By creating images at different resolutions, students investigate how changing the number of pixels affects the amount of visual detail while preserving the overall image.

Learning targets

  • Define pixels, pixel art and abstraction.
  • Explain how pixel art relates to other artistic styles such as mosaics and pointillism.
  • Create analog and digital pixel artwork.
  • Use abstraction to simplify a real-world image while preserving its most important features.

Steps in the lesson

  1. Warm up

    5–7 minutes · Slides 3–5

    • Ask students whether they have seen pixel art before and invite them to draw or describe what they think pixel art looks like.
    • Share examples from familiar games such as Minecraft, Among Us, and Super Mario to activate prior knowledge.
    • Review the agenda and explain that students will learn how artists and computer scientists use pixels to create digital images.
  2. Whole class instruction

    10–15 minutes · Slides 6–13

    • Introduce pixel art and discuss where students encounter it in everyday life, including video games, digital art, and animation. Define a pixel as the smallest unit of color in a digital image, and explain how many individual pixels combine to create pictures on computer screens.
    • Compare pixel art to historical artistic traditions including mosaics and pointillism. Facilitate a discussion about similarities and differences among these artistic styles.
    • Introduce abstraction by explaining that artists sometimes simplify images into fewer visual elements while still communicating the original idea. Abstraction is a big idea in FRACTAL because it is important to computer scientists and artists.
  3. Activity: Paper Pixels

    25 minutes · Slides 14–18

    • Introduce the goal of the activity — "Use graph paper to make a pixel art image on paper" — and the overall process of the activity.
    • Invite students to choose an inspiration image (either digitally by sharing a link or printing copies for reference) or create their own design. Once they have chosen their image, students should think carefully about which details are most important to include.
    • Distribute graph paper and art supplies (e.g., colored pencils, crayons, markers).
    • Circulate throughout the classroom providing feedback and encouraging students to simplify complex images into colored squares.
  4. Closing

    5 minutes · Slides 19–21

    • Artist Interview: pair students together for an artist interview. Encourage students to explain their artistic choices, challenges they encountered, and how to create pixel art on paper.
    • Computers will be needed tomorrow — remind students to bring them to school if this is not a typical part of their school routine.

  • ½ sheet of large-cell graph paper per student

Learner variability

For students who benefit from additional supports — such as step-by-step directions, visual scaffolds, reduced working memory demands, support with spatial reasoning, or alternative pathways to demonstrate learning — consider using one or more of the learner variability resources included with this lesson. These materials provide multiple ways for students to access the content while working toward the same learning outcomes.

Students choose from multiple design pathways that vary in complexity (abstract, symmetrical, or more representational). Learner support sheets provide step-by-step visual guidance, examples, and scaffolded prompts. Students may also create original designs or adapt existing examples based on their readiness and interests.

Background for the teacher

Abstraction
The process of simplifying something by focusing on its most important features while leaving out unnecessary details. In art, abstraction helps artists communicate an idea without reproducing every detail. In computer science, abstraction helps solve complex problems by breaking them into simpler representations.
Pixel
Short for picture element — the smallest unit of a digital image. Each pixel is a single square of color, and many pixels work together to create the images we see on phones, computers, televisions, and other digital devices.
Pixel art
A form of digital artwork created by arranging individual pixels into recognizable images. Because artists work with a limited number of squares, they must carefully decide which details to include and which to leave out — an excellent example of abstraction.
Resolution
The number of pixels used to create an image. Higher-resolution images contain more pixels and can show finer details; lower-resolution images contain fewer pixels and require greater simplification.
Mosaic
Artwork created by arranging many small pieces of colored stone, glass, tile, or other materials into a larger image or pattern. Like pixel art, mosaics demonstrate how many small parts combine to create a recognizable whole.
Pointillism
A painting technique developed in the late 1800s in which artists create images using many small dots of color rather than continuous brushstrokes. Up close the parts appear simple, but they combine into a detailed image when viewed from a distance.

How these ideas connect

  • Artists and computer scientists both use abstraction to simplify complex ideas.
  • Pixel art demonstrates how many small pieces combine to create a larger image.
  • Digital pixel art builds on artistic traditions such as mosaics and pointillism, showing that artists have long created images from repeated visual elements.
  • Learning to simplify an image into pixels prepares students for future explorations of algorithms, coding, and computational thinking.
