I recently heard an episode of RadioLab about the Swedish Navy. It inspired me to think deeply about the Fish Farts of education.

#mtbos I have a person workin' on fractions and my magic lesson didn't work magically, so I have to do it more by hand :) Since the accessibility folks have the 3-D printed fraction pieces, I made my own out of cardstock (LOL a lot faster and still very handle-able). We need practice in going left to right when figuring otu "greater than" or "less than" because when you work w/ building things, you go whatever direction makes sense at the time.
https://resourceroomblog.wordpress.com/2026/08/13/fraction-manipulatives/ is the blog with the most recent files. Self: get them up on the webpage where you've been sticking them because if you have everything in a lot of places you're more likely to find them again as well as I wantthem on MY website not wordpress. (I tried doin' the blog thing on my site but got slammed with spam.)

My TWO steps for creating a classroom culture that embraces productive struggle.
Step 1: Teach wide math, not narrow math.
Step 2: Explore-first instructional strategies

I jotted down my thoughts here: https://duanehabecker.substack.com/p/building-a-culture-that-embraces

This idea of writing a book has suddenly become very real! Here is the book cover of our new book.

@Em0nM4stodon I long for more happening at #mtbos "math twitter blog o sphere" and #bikeTooter is awesome too.

Hey, it's about to be a new school year... let's revive :) For 3 weeks I did aonce a week blog post for adult ed that I shared w/ the Adult Numeracy Network (which has their own online discussion)... but I'm thinking of being a wild crossposter. Today's goal: figure out the routine for that.
ICYMI here's how to make good number lines really quickly with PowerPoint: https://youtu.be/Rm1o7SWzoa4?si=-S5HwbUSRoS4MIb2 SELF: include accessibility info into the routine.

I'm starting a new series for Art prompts on Fractal Kitty. Here is the first post playing with hailstone numbers

I wrote a post about the embedded interactives on my site:

This is not to say the lecturer is absolved of responsibility to make the teaching good, and this is perhaps really only applicable at the higher levels of mathematics, but I think I agree.

I was looking for #mtbos "concrete-representational-abstract" (CRA) lesson ideas for rounding.
I found a 134 page dissertation wherein there are no illustrations, so the table for building the numbers is ... described. I've skimmed it and it includes an acronym with the steps to do, which is a red flag for things not really being C R A but only a yellow flag in a dissertation :P We'll see.

@rakontisto hashtags have hope. I'm gonna keep trying. #bikeTooter is fun and informative but I ferociously miss #mtbos ...

#mtbos I've been blogging some place value things. https://resourceroomblog.wordpress.com/2026/07/20/numeracy-and-mathematics-place-value/

@futurebird #mtbos
F'rinstance, one asked last week: how to know whether to add or subtract when solving an algebra problem? First, getting to where they knew how to ask that is huge.... this just showed up on my FB feed with That Common Issue (what does the equals sign mean?)

I’m a better mathematics instructional coach thanks to my trip to the top of Willis Tower in Chicago.

I'm wondering if it's something abotu mathstodon.xyz that means I am not seeing any images on mastodon any more. (LOVE the alt text...)

@mpershan wrote an embarrassingly enthusiastic post about my curriculum development efforts. I blush!

This is how to *progress* from the concrete to the representational.

It has been a while since I've last blogged. This one was inspired by a Popular Science article about placebo buttons.

#mtbos #iteachmath LOL Karen Campe I did a blog post too.... towards a more specific situation and audience, and ... shorter b/c I want to make a bunch of them. https://resourceroomblog.wordpress.com/2026/06/29/numeracy-post/
It's talking about the manipulatives I have just lyin' around in the tutoring center. Somebody on LinkedIn posted about it being bad to have 'em all tucked in drawers (but I never did find the actual post), which made me feel justified in being a person who Forgets to Put Things Away.
The next installment will be handouts and visuals .... but the ONE AFTER THAT will be about the hidden conceps that if I take time to help my learners build, enables pretty ferocious progress.
Okay, my pre-algebra to pre-calculus person is not typical (like those diet ads, right?) but it really was about "this is how you need to work with these problems."
