So! I'm having lots of fun with my new side gig writing supports for students with disabilities for Illustrative Mathematics' future high school math curriculum.
They say with this edition they can't include images ... but ... it will be published as CC-BY Open Educational Resource which means that once it's "out there," anybody can add, modify, etc. To that end, when it's *slightly* quiet at the regular job but not quiet enough to actually switch to working on the side one... I've put together some visuals that could go along with them.
So! People sometimes have to do long division and ... it really helps some of my folks to have a structure for making sure the same place value or like terms line up. I've created a "gazinta" (there's apparently no name for the symbol :P) ... and a video about polynomial long division to add to the ones already out there (but mine's CC-BY so nobody has to ask permission to use it ;)) https://youtu.be/P9tKzg0hu_w is the video...
