Coding to Create · Lesson 4
Over two days, partners transform a famous portrait or landscape into a geometric artwork, document their algorithm, write an artist statement, and curate a class gallery.
Students explore how artists and programmers use abstraction to focus on the most important details. After examining examples from artists such as Roy Lichtenstein and Adam Lister, students work with a partner to transform a famous portrait into a geometric artwork using simple shapes. They then document the algorithm they followed, write an artist statement describing their computational thinking, and curate their work as part of a class gallery.
Note: this lesson is designed to stretch over approximately two 45-minute class periods.

This lesson provides multiple entry points for students to engage in geometric abstraction. Students choose from a range of inspirational artworks, receive optional visual scaffolds such as tracing and shape-identification supports, and work collaboratively to create and explain their artwork.
Structured handouts, sentence starters, and multiple opportunities to represent their thinking through art, writing, and discussion ensure that students can access the learning goals through multiple means of engagement, representation, and action and expression while developing an understanding of abstraction, algorithms, and artistic communication.
Students can also work independently.
| Artist | Artwork referenced | Computational thinking connection |
|---|---|---|
| Adam Lister | The Scream (reinterpretation) | Shows how artists can abstract familiar images into geometric forms and use pattern recognition to recreate them. |
| Edvard Munch | The Scream (1893) | The original artwork students compare with Adam Lister's abstracted version — one image can have multiple representations. |
| Leonardo da Vinci | Mona Lisa | Shows how a realistic portrait can be simplified into essential shapes while preserving recognizable features. |
| Amy Sherald | Miss Everything (2016) | Encourages students to identify essential colors, graphic elements, shapes, and proportions when creating a geometric portrait. |
| Vincent van Gogh | Self Portrait (1889) | Demonstrates how complex portraits can be represented with simplified forms while maintaining key facial features. |
| Johannes Vermeer | Girl with a Pearl Earring (1665) | Encourages students to identify the defining features (headscarf, earring) that make a portrait recognizable before simplifying it. |
| Ramón Frade | El Pan Nuestro (1905) | An opportunity to abstract a realistic portrait by focusing on important shapes, the full-length body, and color choice. |
| Rick Bartow | Waving Bear (2012) | Even sculptural forms can be analyzed, simplified, and represented using basic geometric shapes. |
| Ernie Barnes | Basketball landscape artwork | Encourages students to simplify people, movement, and environments into key shapes while maintaining the overall composition. |
| George Bireline | Part II | Landscapes and interior spaces can be represented by identifying large geometric forms, color blocks, and spatial relationships. |
| Sarah Blakeslee | In the Woods | Encourages students to recognize repeating patterns in nature, such as tree trunks and vertical lines, and simplify them into geometric forms. |
| Eric McRay | Collage and painting works | Demonstrates how complex 3D objects such as buildings can be simplified into shapes through both collage and painting. |
| Tucker Cooke | Women in Three (2015) | Groups of figures can be simplified into essential shapes while preserving relationships between people and space. |
