Dr. Robinson introduces the Desmos 3D Graphing tool, an essential resource for educators working with blind and low vision students. This tool allows users to create and manipulate 3D objects, enhancing the learning experience for students who require tactile or visual aids. As a teacher of the blind, Dr. Robinson emphasizes the importance of providing accessible 3D objects that students can manipulate as they learn. She demonstrates how to use Desmos 3D Graphing, starting with a simple circle and transforming it into a 3D cylinder.
Throughout the demonstration, Dr. Robinson highlights the seamless integration of Desmos 3D Graphing with braille displays, ensuring the content is accessible to students with visual impairments. She manipulates the cylinder’s size and shape using various commands, showing how easy it is to adjust these parameters in real-time. This hands-on approach allows students to understand the relationship between mathematical equations and their 3D representations. A 3D printer can create image or acquire an actual can of soup to compare to a circle/cylinder for further student understanding.

Dr. Robinson further explores Desmos 3D Graphing by adjusting a parabola into different shapes, including a “blob” that can be physically modeled using clay. This tactile method helps blind students grasp the concept of changing variables and their impact on the graph’s shape. The ability to adjust and visualize these graphs is particularly beneficial for students preparing for tests or needing to solidify their understanding of complex mathematical concepts.
In addition to demonstrating the tool’s functionality, Dr. Robinson encourages users to explore more on the Desmos website, including the blog and available shortcuts. The continuous improvements in Desmos 3D Graphing make it a powerful tool for blind and low vision students. By integrating this tool into their learning process, educators can significantly enhance the accessibility and engagement of math lessons. Desmos 3D Graphing provides an invaluable resource for making advanced math concepts accessible to all students, regardless of their visual abilities. Other Desmos Lessons here…
