There is no class on Monday, September 28. Instead there is class on Tuesday, September 29
Tuesday, September 29
Before class:
- Required Readings: Read these resources about the elements of art and design:
- Understanding Line in Art
- Five types of lines in Art
- The Seven Elements of Art.
- The Principles of Design from the Getty Museum.
- As a first step toward the artwork you will be creating for Project 1, complete the following steps:
- Your goal is to draft five different initial sketches that could form the basis for your final piece of art.
- You can start these sketches on paper if you like, however it is very important that you work to translate your ideas into mathematical functions and display them in Desmos.
- You may find it helpful to think about the visual properties you are going for in your sketches, similar to the groupwork we did in class on Wednesday 9/23. Feel free to use the resources above to find some words to describe the properties that you want to explore. Write those words down so you can remember them later. (More words: HERE, HERE, HERE.)
- You should use Desmos as a sketchpad. Start off with a parent function (or a couple), and use the techniques from class to modify and combine the functions to a desired shape and size.
- Once you have an initial shape that works for you, save the notebook. You should be creating many different notebooks, one for each seed of the drawings you wish to explore.
- Given this initial shape, start to introduce parameters that transform the initial shape, following the steps in the Youtube tutorial I posted before about using Desmos to create Mathematical Art.
- Once you have tweaked your sketches sufficiently that you are happy that each sketch matches the idea you are aiming for, export the five sketches to five SVG files. (Reminder: Video from last time about exporting your artwork to SVG.)
- Go to Campuswire and click on "Chatrooms". You should be a member of a room that says "artwork-critique-groupX" that matches the group you were in on Wednesday. Post your five SVG files to this room before class. I am expecting five draft artworks from every person, each with its own style. If you end up with fewer than five, post the ones you have before class, and post the remaining ones later.
- Write one or more paragraphs (5-7 words) reflecting on this process and submit it here.
- I highly recommend working together with classmates on these tasks. I understand that some people may find this assignment challenging, so it will be helpful to have input from someone else who is working on something similar, in order to ask each other questions as you go along.
In class:
- Discussion of the process of creating function based artwork.
Wednesday, September 30
Before class:
- Use the discussion from class on September 29 to benefit your creation (or revision) of your five pieces of artwork. Complete the assignment that was due Tuesday September 29, including the one or more paragraph that accompany your work so far.

Modify your artwork as you see fit based on the new information about your pieces and what you learned from your classmates. You are permitted to start from scratch, but if you do that, make sure you also subject your new works to outside critiques (classmates or family).
- After sitting with each piece for some time, choose one of the two artworks you developed to be the piece you will submit for your first project.
- Spend some time to finalize the parameters of that one piece. Make sure you remove the grid lines from your artwork so it only has a white background.
- No later than Sunday night: Complete and organize your Desmos notebook, export your artwork to SVG, and complete your one-page writeup. They should be in a final form. Send the files to your peer review partner(s).
- No later than Monday night: Complete this peer review form, request a copy of your submission by email, and forward this email to your partner. (When you submit the form, the submission goes to me—I am verifying that everyone is providing and receiving constructive and usable comments. You must forward your confirmation email to your partner.) Determine a good time to meet by video on Monday to give oral feedback about their work.
