HELP? Does anyone have (or know of) a unit/module for high school math that teaches students how LLMs work while also teaching the relevant math (encoding, matrix operations, probability, etc)? cc: @jedediyah.com @danshuster.bsky.social @dandersod.recursiveprocess.com @comapmath.bsky.social

I am the current chair of the US National Commission for Mathematics Instruction. Our commission represents the US in an international community of mathematics education under the auspices of the National Academy of Sciences. Our very modest NSF funding has not been renewed. #iteachmath

Spreadsheets! I just started working on a short spreadsheet intro for my students. It is super rough and was not planned out ahead of time (it is super hackish), but it is fun! jedediyah.github.io/cds/spreadsheets Happy to hear ideas 😊 #iteachmath #mtbos

I created this free game for my #astronomy students to get a sense of relative sizes of solar system objects. Adjust moon/planet/comet/etc. sizes, lock in guess, & score accuracy points! Made entirely with #AI Would love your feedback gregschwanbeck.github.io/scale-game/ #AIEDU #EduSKY #edchat

I'm looking for a copy of the 1989 Curriculum and Evaluation Standards for School Mathematics from NCTM. Ideally as a PDF... #ITeachMath #mtbos

Just got this, and it looks like a straight-up classic! I wish I knew more about the history of these collections. Particularly how the content has diverged from current NCTM positions and some great resources have gotten kind of lost.
