I hope to have a follow up post on it in the next day with another extension.

I got tired of counting squares. (prototype)

I got 122 today playing with it - what can you get?

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.

At @recursecenter in our Annotated Turing study group we got talking about diagonalization. I made a joke - then I made a poster and bumpersticker to go with it.

It's always a fun conversation to have - what is real - what can we express - what can we compute

Codepen asked for spirals -

did I miss any? (no I didn't do ulam - should I?).

I brushed up on my Desmos teacher activity builder skills in Desmos today and made a small intro to Conics.

Hi all, a new #introduction for my new account on Sharkey. I'm Nick. I'm a #computerscience and #engineering secondary school #teacher in #Baltimore, Maryland, USA. I'm interested in #ai #artificialintelligence and #MachineLearning, #robotics and #automation, #Android #appdev, #cybersecurity, and more. I'd love to connect with other #csed folks from elementary to industry, folks interested in #engineeringeducation, and consider myself part of the #MTBoS #iteachmath community too. I also enjoy connecting to people outside my teaching roles! I enjoy #cats, #mystery novels, #nature walks, #travel. I care deeply about fighting for #peace, #socialjustice, and similar goals. And I also like thinking about the intersection of #stem with those goals, for example #aiethics and #RenewableEnergy. Testing out Sharkey on this new account, but I do have two other Fediverse accounts that I've had for a few years each (listed in bio) in case this account goes dark.

. @j_lanier is hosting a math talk on Zoom at 5pm ET tomorrow (Fri June 28) as part of his "21st centuary mathematics" learning experience for K-12 math teachers.

Clyde Kertzer, Kate Stange, & Summer Haag will talk about their work on circle packings. Math teachers - fill out this form for the Zoom link. Will be fascinating! 🧮🧪

Lots of interactive online learning activities have nifty visual displays of student progress (ALEKS, et al).... is there a way to generate something like that in D2L or Moodle? I remember figuring out the code a million years ago in HTML / Javascript but if there's something already there

For a long time I was struggling with how to organize the various useful websites that I have found for math, science, teacher tools, and general fun. A few years ago I decided to organize them into a Google slide deck, and it seems to be working much better for me.
And now I share with you all....

1) Hello, I am a HS math teacher in SoCal. I've taught everything from Basic Math (back in the day) to precalculus. Looking forward to teaching AP Precalculus in the fall.

2) First apple pie, second donut and third cake

3) Outside of the classroom, I am a soccer mom. With 2 boys playing club, there's very little down time. Between practices, league games and tournaments, we are busy all year long. In addition to that, I became the photographer for the two teams. I enjoy capturing the soccer action and recording images of my boys doing what they love.

Thanks @jreulbach and @samjshah for bringing us together.

I would love to pick your brain on #SBG @Mathvice I attempted it last year but I know it could be better.

Posting on here definitely feels different and more like posting into the void...but I kind of like it. It's freeing not worrying about a post getting likes (favourites) or replies and just saying what I feel.

Today I've been thinking about autonomy in planning maths lessons. Prompted by many things but brought to the forefront by Craig Barton's blog this morning (Link below)

I'm trying to mentally wrestle with the idea that I have, in the past, disliked being told how to teach if it's too prescriptive...I hated the thought of some structures I'd seen in other schools such as compulsory 10 minute retrieval where the questions were pre-prepared by someone else.
But I also find myself wanting to dictate methods, approaches and sometimes even a whole series of lessons.
But the crucial thing here is that I think I was scarred by some particularly bad ideas. Whole-school T&L policies which were driven by subjects very different to maths. Perhaps this made me resistant to being told to do something.
Now that we know better (I hope), are there aspects that could be much more prescribed?
And could there potentially be more creativity that comes from this? If we give teachers time back with the basics of lessons planned will there be more time for tweaking/adapting/thinking creatively about how to improve things?
