  2. @joshg I wonder if Geogebra has things?
    I share the frustration --> it's folks like @KarenCampe who have been awesome at making things that work for my folks who benefit when even the most basic things made visual. And I sorely miss #mtbos -- there might be a few more people over on bsky.com ...

  3. The first issue of The Mathematical Gazette with me as Editor has arrived in the post!

  5. #mtbos and in the "let's use nice language to limit opportunities," the "Strong Start To Finish" folks write that "almost no one needs college algebra anymore." Also, states are "resdesigning developmental education."
    Once more, how about at least *looking* at why students are getting through high school without the math skills? SHHH.

  6. added a variation of stop-gate(domineering) to play with. After each move, scorch a space one king's move away:

  7. #mtbos so I think I figured out that my Moodle class ... well, you just can't really sign up with your email. (Perhaps something's built into my site architecture for spam control.) But if you know somebody who wants to try a conceptual, little bit at a time, number sense based "course" resourceroom.net/class/ will get them there and I can sign them up :P NO cost or commitment... even figuring out how to get signing up to work is helpful.

  8. #mtbos Today is "professional development day" at the college.
    Batting 1000 on: if there's an educational gathering, *somebody* will bring up fractions as a teaching issue. Every adult ed thing, every math thing... this was an "accessibility in your courses" and as I walked in the room somebody had just said the word before anything had started.
    Yes, they have my email now

  9. bsky.app/profile/davidkbutler. #mtbos this one ... I have no earthly idea how to begin :) :) But I rarely do in geometry and ... often figure things out.

  10. If anyone needs a paint with only circles, here it is. These are drafted toys I use in facilitating math explorations.

    If anyone needs a loopy-doodle math toy here it is:

  11. Finished making a post for Beautiful Chords today with some extra tools. It would be really easy to keep going and make a Monte Carlo for random chords, rotations of connected shapes, moire strings, shadow art with strings, etc.

  12. Some pundits (and some colleagues) claim we teach too much math. How do we respond? I'll share some thoughts at the CMC-North conference in Asilomar.

    I hope to see some of you there!

  17. A new inquiry activity is posted on Fractal Kitty!

    fractalkitty.com/inquiries-wee

    This one plays with graphs and can be used as an extension to Sim, Don't Make a Triangle, and other such games.

  18. So I had two tasks at #NCTMATL25 (besides presenting with Cynthia Shi) ... see @pegcagle and Gail Burrill ... mission accomplished! And a bonus visit with Vicki Lyons
    Forgot to take a pic with Peg & Vicki, but I got Gail!

  19. Each representation is correct, but which are helpful, at what stage, and for which purpose?
    #nctmatl25 #mtbos #mathed

  20. So the previous session mentioned procedural fluency versus conceptual understanding.
    The next session drove the point home.

  21. The only reason I would want to teach small children would be for the contexts - & sketches - they create!
    #nctmatl25 #mtbos #mathed

  22. Use "Create a mathematical sketch" rather than "draw a picture"
    (it was referenced from another session so I don't have a reason why atm)
    #nctmatl25 #mtbos #mathed

  23. Note to self ... Look up research on gesturing in mathematics education.
    If any of you out in the #mtbos have some ideas ...

  24. "Because of the abstract nature of mathematics, people have access to mathematical ideas only through the representations of those ideas" from Adding It Up.

  25. Oh... The exhibit hall at #NCTMATL25 isn't open today, now that I have some time.

  26. "I want procedural fluency from conceptual understanding"

  27. The session had us ask our favorite #AI what we should do in Atlanta while at
    @NCTM

    I love #chatOAME :)

  28. LLMs are based on dynamical systems, yet we don't do any of that mathematics in K12 -- even though we had standards and courses in some jurisdictions for high school (#onted did!)
