Tomorrow in class we’re uncovering the sine law, which I’m gonna give the subtitle of “every triangle is a right triangle (well, two)”, giving major Mitch Hedberg vibes
Did a fun #OIFMath today with sinusoidal functions, tweaked from the original found at natbanting.com/oops-i-forgot
So how much money upfront is that, truly, the math teacher in me asks. Still $0, says everyone
The youth are an unstoppable force and I love every second watching them flourish
After Elizabeth Yao's valedictorian speech last Thursday - in which she discussed the children killed in the war in Gaza - her principal called and told her not to come back to school on Monday. www.cbc.ca/news/canada/...

Leaving school tonight, about 25 mins after the bell, I see two grade 9 students from my classes walking around… Me: it’s Friday after the bell! It’s the weekend, you’re allowed to go home A: This /is/ our home

Alex Kirshner@alexkirshner.com · last yr.this is a letter to the editor from a high school track runner who came in second to a trans girl in a race. her state house rep in maine started talking about it. so she wrote this: www.pressherald.com/2025/05/14/r...
Led a warmup activity at a staff meeting tonight. Gave a handout, offered pencils to those who needed them. Went pretty well. What will stick with me though is the negative. “Do we have to do math? Ugh”
Thanks for this, Dan! A colleague of mine adjusted the plans slightly to cut down the creation time (took about 6 hours for our printer to make this green one). Looking forward to extending the lives of these!
Dan Anderson@dandersod.recursiveprocess.com · last yr.Hey, I made this thing at the beginning of the year and I think the markers last a LOT longer when stored upside down like this. If you have access to a 3D printer and you use the standard EXPO markers, give it a try? www.tinkercad.com/things/c8xgO...
Cost was about the same, so do I choose one hardcover copy or five paperbacks? Easy decision. Might as well spread the math love ☺️ cc. @triangleman.bsky.social
“Speaking freely” is not the same as “speaking truthfully” and that is worth noting.
Severance brings a whole new meaning to “I’m my own worst enemy”
1/2 Last Friday at our math-specific PD day I nervously offered a session on solving linear equations with a double open number line. It went better than I expected! Thanks to @pwharris.bsky.social for the inspo, @mathigon.bsky.social for the platform, and everyone who attended :)
Ultimate tic-tac-toe art school edition, bunnies vs cyndaquils
Yesterday's talk with my #MEL4E class about last week's Ontario election and the: ➡️ importance of being engaged citizens ➡️ probability of winners in the days leading up to the election ➡️ non-proportionality of votes vs. seats won in our current electoral system Big thanks to @338canada.bsky.social
The unusual baker strikes again. The discard pile (along with only three piles for students to get new Qs from) was a good move #MTH1W #ThinkingClassrooms
If you believe students don’t have math trauma, test that theory by having them write a mathematical autobiography. I learned so much about who they are and what they bring to the classroom. BTC as math therapy, merging the work of @themathguru.bsky.social and @pgliljedahl.bsky.social this semester
If the heart of your pitch is “math sucks”, maybe you shouldn’t be in the math ed space
Thank you so much! It's live now: slowrevealgraphs.com/2025/02/09/w... (I added a light color version with your questions to make it easier to annotate, but the dark color scheme is prettier)

Preface with tally marks from different countries, use binary/Roman numerals/french numbers to describe how operations and structure are often baked into number systems, then create the numbers 0 to 20 with this number system. Then, write 24, 36, 48, and 223 in this system. #ThinkingClassrooms
Some of the best Tax Collector thinking I’ve ever seen. Knowledge mobility was 🔥 #ThinkingClassrooms

Planning to document one thing a day this semester on here. Let’s build this place into the learning community it can be.
Good morning! Number one way in the coming weeks to support the work that brought you Which One Doesn't Belong?, Tiling Turtles, Math On-A-Stick, and the Hierarchy of Hexagons is this: Pop into your fave bookstore or library to ask for How Did You Count? ISBN: 978-1032898353 Coming in March
Wrapping paper with grid lines on the back takes me from “ugh everything I make is ugly and this is the worstttt” to “this is just playing with angles, fun!” and now my life has changed forever
Good grade 9 question or nah: If y=mx+b is the format we usually refer to for linear equations, and m and b have specific meanings, what if we wrote x=ny+c? How do n and c connect to the graph?
