For this assignment, I explored Ali and Colin's concentric circle number representation activity inspired by the work of Wassily Kandinsky.
This week’s activity had me stretching my thinking in multiple ways. First, I found a sense of wonder in the way Sarah Chase’s brain worked–moving multiple parts of her body in a seemingly seamless choreography of dance. Thank goodness she broke down her ideas into moving ‘3 against 2’ because my body and brain could manage that activity. I marveled at how grounding the movement into thinking of mother, myself, father, summer, and winter made it all somehow more doable. I found myself enchanted with this activity, though I admit, I didn’t take it further to try to extend the activity. Mostly, because envisioning trying to have my grade 3s do such an activity made me feel instantly stressed. I could try this with a small group, but decided to look at Ali and Colin’s concentric circles instead as this seemed more in line with what my class would embrace and like to wrestle with.
The first thing I decided was that I needed to remind myself how base 3 worked. I instantly felt a pang of jealousy toward those that could whip out any base–something counting system like it was a breeze. I was briefly distracted by thinking about how I could use Kandinsky circles to round numbers to the nearest ten, but first wanted to try the activity as presented. I decided to try base five with the Kandinsky circles and realized how accessible base five felt. I suddenly felt like I could handle any base–well at least I knew if I didn’t get it, I just didn’t get it yet. Armed with four colours (white=0, purple=1, blue=2, red=3, green=4), I began trying to code my circles using base 5, and division was my friend. I also chatted with Claude AI and used the tool as a teacher of sorts, bouncing my ideas around and needing some reassurance that I was doing it correctly. Ah, the need for mathematical reassurance–sometimes I get bogged down by that need and am working on trusting my mathematical gut. I can, I must, I will!
I found creating this Kandinsky inspired art to be relaxing. I felt that the more time I could spend with it, the more it would make sense. I started with the numbers 1-16 and then wanted to know what would happen if I tried 77-80. Finally, I was getting to use the outer ring! As I was doing this activity, I realized that my students aren’t dividing yet and that this would be a difficult activity for them. This is where the integration piece from our course readings became crucial-I didn’t want to just abandon the mathematical depth of the activity, but I needed to make it developmentally appropriate for my group of students.
Extensions I explored and could use with students:
Base 5 instead of base 3
This would be more accessible to grade 3’s than base 2 or 3 as the numbers grow slower, patterns are clearer
Adapted using circles for rounding to the nearest ten
Innermost ring = odd/even
Middle ring = lower decade
Outer ring = higher decade
Adapted circles for use with place value
Each circle represented ones, tens, hundreds and could go to thousands with four rings
Floor circles using for embodied place value (explored in my mind)
3 concentric circles on the floor/draw on blacktop
Students jump in each ring corresponding to place value
Example-361: jump 3 times outer, 6 times in the middle, and once in the center
Kinesthetic understanding of magnitude
Makes abstraction concrete
Curriculum Ideas:
Guiding Questions:
How can numbers be represented in multiple ways?
Can visual and physical representations deepen our understanding of an idea?
How do we create systematic notation?
Possible Learning Arc:
See, think, wonder-Look at Kandinsky artwork and the Chamberlands’ mathematical version
Explore creating circle for chosen numbers
Discover patterns, compare with classmates
Detective work-decode each other’s circles
Innovate: can you invent your own system?
How does this connect to our base 10 system?
Embodied Learning Ideas:
Floor or blacktop concentric circles for jumping place value
If group understands other bases, could also jump base n patterns
Give students manipulative for grouping in new bases
Create large scale outdoor version with sidewalk chalk or paint a mural on bulletin board paper
Art:
Colour choice and design
Variety of mediums
Start a mathematical art gallery (I have started hanging up some of my work)
Learn about Kandinsky (also connects to language arts and social studies)
Pencil Paper Math:
Math journal reflections
Problem solving
Place value notation practice
Many lessons on base system after exploration
More Possible Extensions:
Students invent their own base/colour system
Can students create a way for this to express skip counting by 10 or any other multiple
Try adding/subtracting with circles
Explore number properties through patterns (primes, multiples)
Use larger numbers, needing more rings
Challenge: create mathematical art with systematic rules
Add to Math and Mingle night as a family activity
Different colours for various decades

I really appreciate how thoughtfully you are adjusting the level of difficulty for your students. The range of complexity and the choice of extensions are especially meaningful and definitely worth trying. Thank you for sharing your ideas.
