@tguindon.bsky.social @annlovesmaths.bsky.social @thestarcaller.bsky.social @ash-bans.bsky.social I just found the 3rd book by Dr. Shih. It is called MathGraf, and the single copy my library could find that exists *only* in a library in Hong Kong. In negotiations for a scanned table of contents now.

This is FABULOUS! What a great way to show off what Dr. Shih did in his book. Love it! Thank you Tim.

I have two books by an author, Keh-Gong Shih, pub in 1996 that are just brilliant! But they are definitely lost. The first is PIctorial Mathematics: Patterns. It is fabulous! full of images like this. He created his own software called Mathgraf which is used to generate the images. #mathart #mtbos

👋 Here is a zip file with all the handouts & slides people uploaded from the NCSM & NCTM annual conferences last month. Scraped the conference website. 400 files. 1GB. Who loves you? Me, that's who. limewire.com/d/nQXRY#AX97...

Think a #NoticeWonder shirt would be awesome? It could be a reality if you move fast! The store is open today through Nov 9. Hopefully enough styles, sizes, and colors to suit everyone. #ITeachMath #MTBoS

Hi Blue Sky! I edit the Journal of Humanistic Mathematics. We publish articles, essays, #fiction & #poetry on doing, teaching & living of #mathematics. So far we had more than 850K full-text downloads of our content - why not check us out? scholarship.claremont.edu/jhm/ #math #openaccess #mathart

I met with my knot theory independent study students today. The topic: braids. I broke out these "BraidTiles" that I made several years ago. You can download a printable pdf here (recommendation: print them on cardstock): divisbyzero.com/2019/05/01/b...

This is a real sign from a real deli near the Wesleyan math department, and they put it up because the mathematicians were too engrossed in their mathematics discussions to efficiently order sandwiches. www.cbc.ca/radio/asitha...

The new surface-colouring option in @desmos.com 3D allows a cute way of visualizing conic sections. www.desmos.com/3d/fiv5gnltdl (The option to have translucent surfaces doesn't save with the graph itself, so needs to be re-toggled on. It's important for seeing the full curves) #MathSky #iTeachMath

#NCTMATL25 reminded me that conferences are really about people. The sessions are great, but the best moments happen when you connect with fellow educators, share ideas, and leave inspired. Grateful for every conversation in Atlanta! #EdChat #MathEd #edusky

It’s amazing to me that we still have people cherry picking what they think qualifies as research-based best practice and castigating @nctm.org based on those biases. Seems a good time to remind everyone that NCTM runs the top tier research journal in the field. #iteachmath

This is so important. I wish a teacher had done any of these for me. I just learned coping techniques on my own.

This I posted on Twitter in 2020 is currently experiencing a resurgence.

Now that #NCTMATL25 is over, The next best thing is to scroll through all of the posts from the hashtag and follow everyone I wasn't already following. Great way to build a wonderful list. Thank you all for a fabulous week!.

Running R code on your phone... that is definitely magic!! webR also makes it super easy to create #rstats learning resources that students can work with using just a browser, no install drama needed. jen-richmond.quarto.pub/barbarplots/

@misscalcul8.bsky.social Just wanted to let you know I shared your bell work posts with a teacher intern. You are amazing, and what you do matters! Thank you so much for all you do Elissa!

My entire program uses these at the undergraduate level. They matter so much! And my students appreciate the thoughtfulness.

I presented on this problem today! You can find the slides here: docs.google.com/presentation... I don't use speaker notes (just vibes) but I think a recorded version exists and I'll try to link to it if/when I can. cc #iTeachMath ♾️ bcc #MathSky 🧮

Shelli’s sister asked me to share that “the service is going to be on the funeral app after the funeral. Please tell everyone to watch. They may see their picture. All the songs are going to be her singing.”

The funeral service for Shelli Temple, @druinok.bsky.social will be held July 9, at 10 AM in the CHS Activity Center. The obituary & additional information will be updated on the funeral home website as it becomes available. www.johnsonsperry.com/obituaries/s... #MTBoS #ITeachMath

The Trump administration is currently holding hostage nearly $7B in federal funding for K-12 schools--funding that was supposed to be distributed yesterday. They've stolen $80M from Wisconsin students and teachers alone. How much have they stolen from your state? www.edweek.org/policy-polit...

This is worth 3 minutes of your time. No one wants to eat at a restaurant that only serves bland chicken. (It’s not about chicken, or restaurants, tho)

Some thoughts about the military parade in my hometown of Washington DC today -- specifically, the route. Military parades in DC are quite rare. But when they happen, they have always begun, symbolically and geographically, at the Capitol and moved outward. 1/

It's time to kick off #MathPhoto25 with #squares! Hunt for square shapes and perfect square numbers. Take photos & share on Bluesky using the hashtags #MathPhoto25 and #square. Please add alt text to your photos for increased access. #ITeachMath

Some time ago, a mathematician (who I *think* was Kate Poirier but I'm not sure) designed a series of icons/badges/somethings along the lines of "Mathematicians for ABC" where ABC was equity, inclusion, and the like. I found one on Zettle, but is there a canonical resource for these? #mathsky

there's a page on Zazzle too: www.zazzle.com/store/mathfo...

Anyway, you should read Francis Su on this: www.amazon.com/Mathematics-... This book really influenced me to see math as a kind of pump for all sorts of virtues-- patience, thoughtfulness, humility, etc.

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

Yes, Glenn!! That study is a cornerstone of our focus group work with students in schools, and our results reflect the *exact* same trends: bsky.app/profile/covi...

The bipartisan conventional wisdom about America’s “failing schools” & the decline of of the American student is the result of a deliberate project to shift responsibility for economic precarity & inequality away from industry & policy and place it squarely on the shoulders of educators & schools.
