I loved seeing the open with the tasty-easy axis. When I came across your idea of visual media for teaching, one of the first things I did was remember reading that comic and go grab that image to open my unit with. So glad to see you use it too. I gave them some fruit on the graph, and my favorite question was, “Which fruit is misplaced?” Riotous discussion. Come to think of if, you could teach an entire unit on the cartesian plane from that image. “I only eat fruit in the peach to grape domain.”

Great presentation.

The assumption (both on your part and on the audience member who asks about it) that a digital projector setup is required for this seems weird to me. Granted I would way, way prefer to have one to do this kind of work, but during my practicum I did not have one at all and I made some stuff work anyway.

For one problem I just handed out photocopies of the image I wanted them to work with. I asked them the question verbally, and they had to construct their own mathematical structure on paper. (It was just taking measurements on a scale photograph vs a real object, so the structure wasn’t too complicated.)

I could see this working with an overhead transparency system too. One transparency for the visual, one for a grid to overlay and mark up w/ points and such as needed. (I really dislike writing on those things though.)

That said, I want a proper projector next time I am running a math class. I will friggin’ buy my own if I have to.

(Watching this in chunks and I’m only partway through, so apologies if this gets discussed later.)
