Reading & response: From Indigenous mathematician Ed Doolittle

By -
Doolittle (2018) Off the grid. In S.Gerofsky (Ed.)  Geometries of liberation.  New York: Palgrave, pp. 101-121. Please read this very interesting piece and write a blog post on it by Sunday, December 8 at 8:00 PM. Suggested prompts: Talk about 2 or 3 'stops' you had in reading this: things that stopped you, surprised you, etc. Think about how this paper might offer new approaches to Indigenizing mathematics curriculum and teaching. Does it challenge or stretch any of your ideas around this? The author questions the grid concept "We know well the benefits of using the grid, but what are the  dangers? What are the preconditions for the grid which may not be satisfied in real-world applications? What are the extremes at which the grid can  fail? What are the consequences of failure? And what are the alternatives?" This questioning process makes me think of the development of Non-Euclidean geometry which also starts from questioning the truth of Euclid's 5...

Blog Reading - Thinking of Math Textbooks

By -
Here is an interesting critical-thinking take on the ways that math textbooks may 'speak to' their readers (assuming that people actually do read and listen to math textbooks...) Wagner & Herbel-Eisenmann on math textbooks and the ways they may position their readers Please read this thought-provoking article and blog on: •How you respond to the examples given here -- as a teacher and as a former student •What are your thoughts about the reasons for using/ not using textbooks, and the changing role of math textbooks in schools? The author gave an example that TMM's initial "investigation" whose instruction included much more exclusive imperatives (or "scribbler" imperatives such as "write", "calculate" and "copy" ) than inclusive imperatives ("thinker" imperatives like "describe", "explain", "prove"). I agree that it is appropriate to scribble before thi...

Math Art Project Reflection

Sorry for missing this art project reflection.  The image shown above is the our replica of Mergerate’ art work which is the work we investigate in this project. I would like to thank my group member Kyle for setting up the project on LaTeX. Then we finished coding as a group. In this work, the triangular grids are numbered sequentially beginning with 1 at the centre and continuing outward along a spiral path to 486 at the far left. A triangle is coloured cyan if it is prime, magenta if it is a happy number, and yellow if it is a triangular numbers. The Fibonacci number is represented as a transparent white triangles layered on top. A blended colour is used for integers belonging to more than one sequence.  Following is our extended art work. After group discussion, we decided to include perfect squares and lucky numbers in our extended art work.  We found that the perfect squares produced an interesting "spiral galaxy" pattern with 5 arms that was sim...
