From @desmos.com graph to Tinkercad to a phyical 3D printed object. My first 3D print of a Desmos project. I added a loop in Tinkercad so that I could add a string and hang it. #ITeachMath @edtechcocek.bsky.social

New project alert! Which One Doesn't Belong? Second Edition. I am deep in the middle of writing and would love input from folks who have used the routine in their classrooms. Short Google form here—one page, eight questions, most of them optional: docs.google.com/forms/d/e/1F...

A chess piece planned in @desmos.com, designed in Tinkercad, and printed on a 3D printer. I’m hoping to have my Calculus 12 students design their own chess pieces this year as we explore volumes of rotation. @edtechcocek.bsky.social #ITeachMath

Hi there! 🎃 There's a new episode of Graph Time today featuring special guest Jacqueline! Check out the video where we add interaction to our spider and play with the Graph to build your own web! youtu.be/-aYROWdnaAc?... www.desmos.com/calculator/2...

Hallowe'en Histogram 2025 #MathOrTreat #Halloween2025 Total of 51 (24% decrease over last year), cloudy skies, temperature 12°C after dark. Also notable: the earliest arrival since recording began, at 5:30pm.

Halloween Histogram 2025. The rain stopped this evening and we had the temperature stayed pleasant (13C-ish). 175 trick-or-treaters visited the house... about the same as last year. #HalloweenHistogram #MathOrTreat #StatsChat #ITeachMath

Sara and I made a spooky spider with wiggly legs and its web this week on Graph Time with Sara and Sean! See how we play with math and use it in our work: www.youtube.com/watch?v=kQC_...

If you're looking for a Halloween activity to do with your kids or students, you can make a "Flex-a-ghoul"—this is a Halloween-themed hexaflexagon that I made. There's a printable PDF on my blog: divisbyzero.com/2022/11/01/h...

We’re underway at #NSMTA2025 with a keynote session from Pam Harris! #ITeachMath

Teaching Calculus Creatively with @mathematicspro.bsky.social at #NSMTA2025. Lots of amazing hands on activities to engage students, make connections and activate prior knowledge. #ITeachMath

That’s a wrap for #NSMTA2025. Thanks to @pwharris.bsky.social and Marian Small, our amazing keynote speakers. It was a great day of learning.

The morning sessions on #RichMathTasks at #NSMTA2025 went great. Wonderful participation from everyone!

Tomorrow is the day! The #NSMTA2025 conference will bring together 800 mathematics teachers from across Nova Scotia. A great day to connect, learn and share. #ITeachMath

Gearing up for tomorrow’s #NSMTA2025 math conference. Wearing my most high tech “smartwatch”. Don’t think it’s AI powered…

Excitingly, Today's the opening day of MathsWorld, the new hands-on maths museum in London. I've really enjoyed visiting MathsCity in Leeds, but they've now got a London location too! Details at mathsworld.com

Inspired by #NCTMATL25 to present at an upcoming conference? Both NCTM and OAME 2026 conference proposals close on Nov. 1st. Here are some thoughts on the benefits of writing a math conference proposal. pbbmath.weebly.com/blog/confere... #ITeachMath @oamelearns.bsky.social

Deriving the Compound Angle Formulae today. I quite like numbering the triangles first so the workings don’t look *too* messy #MathsToday #ALevelMaths

#MathsUntangle Probably the best fractions task I've ever written (at least I thought so at 4 am this morning....)

I thought Y7 might need a warm up to the task in the first picture, so I modelled a couple and got them to try their own numbers on MWB. Brilliantly, someone happened to get 23, 24 and 23. After such a near miss they were all very motivated to try and get a perfect triplet! #MathsToday

Planning my Halloween jack-o-lantern display. Pretty spooky stuff if you're a math teacher. Do you like just the numbers or the numbers with a creapy smile underneath? (two versions from two different AI image generators). #ITeachMath

Just submitted a session proposal for OAME 2026. Looking forward to this always fantastic conference. #ITeachMath

New percentages resources from Y9 lessons this week: ✨Mixed percentages fill in the blanks ✨Compound and simple interest fill in the blanks ✨Missing interest rates practice strips Find them at www.draustinmaths.com/percentages #UKMathsChat #MathsToday

How we animate in Desmos, Episode 3 of Graph Time with Sara and Sean is here! youtu.be/PtrHw9-AFWQ

Did this with my year 13s in #Alevelmaths as a gentle warm up. Getting them to guess what f(x) and g(x) was and to find each area depending on their functions was less gentle! #Mathstoday

Halloween is just around the corner. I made a Halloween treat esti-mystery to share with students. #ITeachMath docs.google.com/presentation...

Apply now to be a presenter at OAME 2026 - Let’s Talk Math. We are looking for diverse session proposals under the following themes: Let’s talk equity Let’s talk assessment Let’s talk technology Let’s talk content Let’s talk pedagogy We would love to have you!!!! bit.ly/callforproposals2026

#Mathstoday Year 10 found expressions for shaded areas. Made this last year for an extension but it was nice spending a bit longer on it.
