The Challenge: Create a penrose triangle.
Materials needed: Pencil, paper, etc.
Math concepts you could explore with this challenge: angles, isometric grids, perspective, vertices/intersections
Depending on how you use this activity, you may engage with different mathematical standards. I’ve listed possible connected math content above. Here are a few suggestions for how you might integrate the 8 mathematical practices. Feel free to add your own suggestions in the comments!
5.) Use appropriate tools strategically. If not using an isometric grid, how can you best create this illusion? How can you test if it is, in fact, an illusion (like that last picture from Katherine Seaton)?
7.) Look for and make use of structure. What parts of an image can be used to make an illusion and which parts not? What are the limitations on the illusions you can create?
