To begin my experiment, I started simple. Based on the concentric circle representation of Binary put together by Ali and Colin, I tried my hand at representing base 4. It wasn't until I was partway through that I compared it to their base 4 representation and found many differences!
Here is mine:
It made sense to my brain to connect the location/size of the circle, the colour, and the number. So, in the first circle, the number 1 is represented by both the size of the circle (smallest) and the colour (red). I used the existing colour(s) until they could no longer combine in addition to create the next numbers. At this point, a new colour and layer of circle was introduced. Because there were only 4 circles, I ran into a problem at circle 15.
While creating this, I found I had to pay close attention! I struggled to consider which circles would work together to create the number I needed. It is clear that my brain is not used to mixing art and math. When I finished, I found myself pondering many questions:
- How could I make it so that I could use numbers multiple times? (For example, use 2 2's to make 4, rather than 3 and 1?)
- Is it necessary for the circles and colours to both represent a number? What would change if only one represented a number?
- How can I bridge this over to higher-level math concepts? My Calculus 12 students are the group that would marvel at this the most, but I don't know how to take it beyond the basic operations.
- What is the next step? Once students have played around with this, where do we go next?
Hi Fiona,
ReplyDeleteThis would be above the level of my early primary students, but when you were asking the questions (before you started talking about math for love) the first thought that came to me was Prime Climb!
And then I continued reading, and there it was!
