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!

Because @rob-baier.bsky.social won't stop bullying me, here's why I'm totally right about trapezoids having at least one pair of parallel sides:

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.

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

Hey everyone!
I'm excited to report that I just moved to Hong Kong to work at the Canadian International School of Hong Kong as a math coach and head of department. I'm in the city and getting set up. So far, it's been a fun adventure.
Does anyone know of any math coach networks in this area?

Asking the UK mathematicians on BlueSky. What is your definition of a face?
In North America, we use this definition in English: "a face is a flat surface (a planar region) that forms part of the boundary of a solid object."
So for a cylinder, the two ends of the cylinder are faces. #ukmath #maths

I blogged again! I had a conversation with a teenager I know who was complaining about needing to learn things they'd never need to know again after the test, and I felt compelled to write about this issue.

I've got a new mantra. I'm unfollowing and muting people who mostly post stuff to tear other people down rather than posting alternatives, offering critical feedback, or best, proposing their own solutions to the problems.

Don't comply.
Don't obey ridiculous and harmful executive actions and laws.
Don't fall in line.
Don't allow yourselves to be ruled by fear.
Don't draw away from your neighbours and family; embrace them.
