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

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!

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)

Man, this targeted ad sure missed the 🎯

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

Started the new semester with a fresh #SlowRevealGraph for my #MEL4E class. Who do you spend the majority of your time with? (Also, feedback for improvement is always welcome) docs.google.com/presentation... [cc. @jennalaib.bsky.social]

Planning to document one thing a day this semester on here. Let’s build this place into the learning community it can be.

I don’t know, man

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?

Today’s #slowrevealgraph was a home run in #MTH1W that was so fun to facilitate and had great classroom discussion. 10/10 keeping this in the “do again” list. slowrevealgraphs.com/2022/11/12/a...
