Kelton and Ma’s article explores how mathematical understanding shifts when classroom space is reconfigured to allow whole-body, multi-party collaboration. Rather than treating mathematics as a silent, individual, desk-bound activity, they argue that meaning can emerge through coordinated movement, shared attention, and spatial interaction. The authors emphasize that embodied activity must remain mathematically purposeful movement is not an add-on or substitute for mathematics, but a medium through which structure can become perceptible. When learners negotiate rhythm, position, gesture, or material together, cognitive load is redistributed across bodies and space. In this way, abstraction grows out of participation rather than preceding it.
Stop 1
My first “stop” in
engaging with this idea came while watching the dance video. As Sarah Chase
layered 3 against 2 rhythmically, I became aware of my own discomfort. I could
calculate 3 and 2 symbolically without hesitation yet holding those rhythms
simultaneously in my body felt complex and disorienting. I realized that I
would need to map the structure or create a visual guide to stabilize it. That
moment made me understand something important: embodiment reveals structure, but
I personally need representation to organize layered patterns. This tension
between bodily experience and structural mapping became the kernel for my
exploration.
Stop 2
The second stop
occurred when I began thinking about cycles more broadly. The dancer’s layered
movements reminded me of seasonal rhythms and how time might have been measured
historically through repeated embodied observation before symbolic notation existed.
The idea that alignment, when patterns coincide, could signal meaning connected
directly to mathematical periodicity. In both natural cycles and rhythmic
dance, repetition and return carry structure.
Stop 3
The
third stop emerged as I considered prime numbers. If rhythms like 3 and 2
eventually align, what happens when the numbers share no common factors? The
idea of working with 5 and 7, both prime, intrigued me because their patterns
would only coincide at a larger interval. This heightened the visibility of
least common multiple as structural alignment rather than procedure.
My Vintage C- Rods
Stop 4
The fourth stop was
material. Knowing I needed a way to externalize the rhythm, I turned to
Cuisenaire rods. The rods allowed me to “freeze” movement into colour and
length, transforming dynamic rhythm into tangible structure.
For my activity, I
selected 5 (yellow) and 7 (black). Instead of using the single rods, I
decomposed each number. I constructed 5 as 3 + 1 + 1 (a green rod and two white
rods), and 7 as 4 + 2 + 1 (a pink rod, a red rod, and a white rod). I then
built two horizontal trains, extending each repeatedly and lining them up side
by side. As the trains grew, the coloured sequences repeated. Eventually, both
trains aligned at a total length of 35. At that moment, the patterns coincided,
and the sequence would begin again. What the dancer embodied as layered rhythm,
I could now see and touch as periodic structure. The least common multiple was
no longer an algorithm; it was a moment of visible alignment.
Cuisenaire rods were developed in the early 1950s by Belgian teacher Georges Cuisenaire as a way to help students discover number relationships concretely. Later popularized by Caleb Gattegno, the rods were designed not as counting tools but as relational tools. Each colour corresponds to a fixed length: white (1), red (2), light green (3), purple/pink (4), yellow (5), dark green (6), black (7), brown (8), blue (9), orange (10). The colours are intentionally distinct and not scaled in a visually obvious gradient, encouraging proportional reasoning rather than visual guessing. From their origins, the rods were meant to reveal structure, equivalence, factors, multiples, ratios, through comparison and construction. In my exploration, they functioned as materialized rhythm, redistributing cognitive load into space, much like Kelton and Ma describe.

Representing a common multiple as alignment rather than procedure also grabbed my attention. Working with fractions is a real challenge for many students and using this concept of alignment then experiencing it in the body seems so powerful.
ReplyDeleteLike you, I instantly felt the need for some kind of written or visual record of my progress. When I started playing with 3 and 2, I talked it out with my daughter she instantly said they would align after 6, but was not able to explain why. So we counted together.
Like the Kelton and Ma article, the article I read by Riley et al. emphasized the intentional nature of the movement activity. It could not be free play and let's see what happens. It is intentionally designed to engage students in a specific math concept and then followed up with (I believe, but this was not completely clear in the article) a bit of direct teaching and pen and paper practice. I am thinking there would also need to be well-designed reflection questions to help students draw connections between the activity and the math notations.
“The least common multiple was no longer an algorithm; it was a moment of visible alignment.”
ReplyDeleteMany students find the least common multiple hard to understand. In a traditional math class, teachers always use factor trees to demonstrate how factors can be taken from a number. However, it is really confusing that many students can’t understand why the specific number is taken out of the original number. It is really abstract for students to imagine the “components” of a number. Indeed, Cuisenaire rods offer a more visual way for everyone to see the numbers clearly.
I remember I used something very similar for my Science 10 class before. In the chemistry unit, when balancing reactions were introduced, I tried the blocks arranging activity with my students. Students had a hard time understanding how many molecules they need on each side to balance the equation, so we tried to use coloured blocks to represent each atom (i.e. oxygen, hydrogen, etc.). In this way, everything is clearly lay out on the table, and students can immedicately point out how many atoms they need. I believe similar activities can be applied to multiple subjects as well!
Tracy,
ReplyDeleteI really loved your post. I also struggled with the body movements for the 3 by 2 rhythm I kept dropping one side or getting off track. It looks so smooth when she does it, but trying it myself made me realize how much thinking is happening in your body at the same time. And when she did 11 by 13 by 7, it felt almost beyond comprehension. But it was beautiful. There’s something really powerful about seeing math happen that way.
I really like your idea of using Cuisenaire rods as a bridge. That feels much more accessible while still keeping the structure of the math visible. It reminded me of a lesson I love using unifix cubes in different colours to represent prime numbers. Each colour stands for a different prime, and we build composite numbers using their prime factorization. Students can literally see the structure of the number — what it’s “made of.” When you build 12 and 18 side by side and compare them, you can see the shared factors. It opens up such good conversations about structure and relationships instead of just procedures. I could see rods working in a similar way before asking bodies to carry the pattern.
And I was so intrigued by your connection to Braiding Sweetgrass. I actually received it for Christmas and it’s on my spring break reading list. Now I’m even more excited to read it after your link to math.
