I'm now four weeks of using the #BTC routine with my students after seeing in action in a workshop with @peterliljedahl.bsky.social.

Today all but one of my students was fully engaged in thinking. It is consistently working really well with my students!
My favorite argument for the inclusive definition is that the area of a trapezoid formula reduces to the other area formulas under the same conditions that the other quadrilaterals do as subsets of trapezoids.

Sal Khan's career is very much a "right place right time" situation and he has not learned a single thing about teaching in all these years.

Did something fun early enough on the internet and got to have his opinions taken seriously forever.
For the remainder problem, I'm well aware of modulo notation, which would be really useful here, but my students are not, and it couldn't figure out how to connect it neatly to a meaningful context for the students. #btc #mathed #mathsky
Here are two tasks I used back to back that worked really well, for my goals for those two days. #btc #mathed #mathsky
Is there a community created pool of thin-slicing tasks for the Thinking Classroom model somewhere?

How are the fraction additions different? How are they similar?
How are the visuals different? How are they similar?

Which visual goes with which fraction addition and how do you know?

Yeah, that definitely seems like a reasonable interpretation to me. I might re-use some of these representations when it comes time to work on the distributive rule.
My plan is to introduce the ways in which I want students to collaborate slowly, over time, rather than all at once.
The activity went very well! Every single student was able to engage with the task and make significant headway without too much work from me. We needed a break from the heavy collaboration we'd been doing over the past while.
Here's a worksheet I gave students today. The idea is to reinforce integer operations (and a chip model) through solving equations. An example of what to produce for an answer is given for each type of problem, except the equations on the last page.

Here's new #connectingrepresentations task I created and used a few days ago with my 7th graders.

How are the number lines similar? How are they different?

Which list of numbers goes with which number line, and how do you know?

Any old #bcedchat folks have a lead on a veteran math history teacher??
BC has a grade 11 math history course!!

Have any BC math educators on here taught this course? If so, what was your experience?
They'd like someone who has merged academia and industry and can give life and career advice. The event is in English because it will bring young leaders together from around the country.

Is anyone interested in helping out?
My son is looking for a volunteer speaker for a student event he is co-organizing meant to inspire and empower university student leaders. The event will be in Montreal, probably on September 20th.
I've created a new streamlined page for my educational consulting services on my website to help schools and educators who are looking for support answering these questions. Check it out here: davidwees.com/services/

Let me know how we can work together!

How can we inspire educators to do the challenging work that is required to develop and extend their practice? What role do routines play in student learning? How do we help educators focus on the right metrics for learning? What role does technology play in student learning?

This diagram encapsulates for me the reason why formative assessment is so critical! It also helps justify the need for visual representations of mathematics to increase the pathways for understanding. #mathed #learning #communication
Oh goodie, customer service is going to get even worse.
Yo, historians, what the actual ****?

I've seen how LLMs handle "history." This is... not good.

Ooo, thanks for the reminder. I might have forgotten about these.
