       Because manipulatives, drawing and anything other than abstract, algebraic or textural representation of mathematical ideas often helps weaker students these potent visual and physical methods of interacting with mathematics are seen as “intrinsically remedial” — to me? This is a terrible mistake.There is a tendency to introduce manipulatives too early and jettison them too early: advanced students are expected, in a sense, to not to “count on their fingers.”

       @futurebird I've had to move the fingers into my head. I keep other counting devices there as well, out of sight, away from the critics.

       @futurebird My last girlfriend had a fairly smart sixteen year old daughter in an algebra class.  She was having trouble with her homework and, since I'd passed calculus (twice!) I figured I was qualified to help her.I spent an hour with the textbook trying to figure out what the fuck angle they were playing at, and eventually gave up.  I offered to teach her real algebra, but she said she'd prefer to pass math class and would figure out the textbook as best she could.

       @futurebird IIRC math was very concrete for ancient Greeks, and yet they were able to create/discover a lot of math that modern, stronger students feel proud to conquer

       @futurebird the first female Fields medalist apparently got a lot of inspiration from doodlinghttps://news.artnet.com/art-world/maryam-mirzakhani-fields-winner-doodler-79848

       @futurebird remember, actual academic mathematicians use drawings as visualization help all the time, to build intuition. So much so that some of them, like dessins d'enfant become formalized mathematical objects. https://en.wikipedia.org/wiki/Dessin_d%27enfant

       @futurebird My 6th class¹ teacher actually showed us a few sneaky ways to count on our fingers without other people seeing.¹ final year of primary school, kids are 11—13
