Reflection to Lockhart’s Lament

The example of music and painting education in A Mathematician’s Lament reminds me of a poem I recently read called The Little Boy. In the poem, a young boy is in his painting class, where the teacher dictates every step of the process. The teacher controls when the students may begin, which colors of crayons they must use, and even what subject they should draw. Even when the chosen theme is something as simple as “dishes,” the teacher restricts the size and shape of the dishes. Under such rigid instruction, the boy is “manipulated” into suppressing his imagination and curiosity. Later, when he transfers to another school where creativity is encouraged, he struggles to break free from these limitations. He has already become accustomed to listening carefully for what the teacher wants and cautiously following the rules, instead of expressing his own ideas. 

I highly agree with the Lockhart's idea that what really need to be done to improve education situation is to hear from our students. This aligns with building an inquiry-based classroom, and it also enhances students' creativity and curiosity. As Lockhart describe, mathematics should involve "wondering, playing, amusing yourself with your imagination." As a teacher, we should leave a big enough space to students to imagine, experience and play with mathematics concept just like how art teacher should give students freedom to create their own paintings. In this process, the teacher becomes a guide and supporter rather than a strict director.

Lockhart criticizes about the giving directions in learning math without discovering by themselves. However, in Skemp's article, he argued about relational understanding and instrumental understanding that both of them has advantages. Skemp acknowledges that instrumental learning can have benefits, such as giving students immediate success and confidence, and sometimes serving as a stepping stone toward relational understanding. At this case, while Lockhart argues rigid direction is largely harmful to students, Skemp suggests that even instrumental learning has potential value when used appropriately.

Reflections:
1. Make sure the materials are all correct and accurate. (I mistakenly switched two scoring term examples in my slides)
2. Need to improve on time-management, leave some time for student questions and properly organizing the 10 minutes.
3. Prepare a hands-on activities. (where i will add different scenarios for students to apply the rule in real life examples.)
4. Course content should be better tailored to the level and background of the target students.
5. Exit ticket questions could be more challenging, as most students were able to answer them correctly this time.

Math Art Project Personal Write-ups

At the beginning of this project, I was doubtful about whether we could successfully recreate Eric Gjerde’s tessellation, since the intricate folds and layered symmetry appeared very complex. However, after searching on YouTube and finding a tutorial, I realized that by carefully following the guided steps we could reproduce the structure and even make our own slightly revised version. Through this process, I noticed that the mathematics behind Gjerde’s original hexagon tessellation relies heavily on 120° rotational symmetry, hexagonal tiling, and repeating twist folds that interlock seamlessly across the plane. In contrast, when we worked on a variation using square paper, the underlying mathematics shifted: instead of hexagonal tiling, the design emphasized 90° rotations, reflective symmetry across axes, and the layering of concentric shapes. This contrast highlighted how different polygons produce different geometric constraints and patterns, even when applying the same origami techniques like pleat intersections and twist folds. 

For me, this showed that origami tessellations are not only artistic but also deeply mathematical, demonstrating concepts such as symmetry groups, angle measures, and tiling properties in a tangible form. I found this process to be an approachable teaching tool, since the folding steps naturally illustrate how abstract mathematical ideas connect to real-life problem solving and hands-on creativity.









Math Art Project Group Write-ups

Original Artwork and Artist: Flowering Grid by Eric Gjerde by Tejom Patel


After our group collectively chose this artwork as our project topic, we faced a big issue of not having resources that lets us perfectly remake the original artwork. The artist, Tejom Patel, had creatively expanded their flower tessellation (based on Eric Gjerde’s work), by adding different folds to produce a new, unique piece. We started off attempting to perfectly mimic Patel’s art. However, due to our lack of knowledge on how the folds and designs work, we had to start off by choosing a design that had guides and tutorials. This was the Spread Hex Tessellation.

Similar to the original artwork, we kept the idea of hexagons and reflectional symmetry, but folded a tessellation where the hexagons overlap and pile up.

Through our research phase, we came across Eric Gjerde’s book Origami Tessellations: Awe-Inspiring Geometric Designs. This resource provided detailed folding tutorials for many origami tessellations built from triangles, squares, and hexagons, and also explained key techniques such as Pleat Intersections, Triangle Twist, Square Twist, and Hexagon Twist. With this reference, we gained a deeper understanding when looking back at our own work, and it also gave us the idea to design an activity more suitable for a short classroom session.


Our interactive activity with the class was a hands-on origami activity where each student folds their own piece of flower that will then combine to create a big multi-piece flower tessellation. Since abstract origami tessellations take a long time to fold, we designed it such that all prep is done (fold lines created beforehand) and students are to follow instructions while helping each other to collectively create one piece of art with the class. 


Here is the link to the origami flower we made in class:

In addition to experimenting with hexagon-based tessellations, our group created a variation called the Layered Compass, which is folded from square paper rather than a hexagonal grid. This shift gave us a chance to explore the mathematical flexibility of tessellation design. Whereas hexagons naturally lend themselves to 120° rotational symmetries and interlocking flower-like patterns, the square base highlights 90° rotations, reflections, and layered symmetry. By adapting the same folding principles—pleats, twists, and repeating units—to a different polygonal foundation, we were able to compare how tiling properties change with shape and how symmetry groups are expressed through origami art. Using square paper also made the process more accessible, since it is a common format and easier for classroom folding activities. Through this variation, we not only made the project our own but also deepened our appreciation of tessellations as a versatile mathematical art form that can be reinvented through creative folding choices.
