Has anyone found it helpful to use Khan Academy regularly in high school math class? We are now required to do 20 minutes of Khan Academy in each lesson because our principal "truly believes this is the additional support our students need." 🙄 🙄 🙄 🙄 #mathsky #iteachmath

Who's going to NCTM in Denver this year? I'm thinking of buying a one-day pass since I live right here! Sadly I was not paying attention closely enough to get district funding, but feeling like it would be worth it to pay my own way for a day! #mtbos

If you were trying to scheme about a math field trip to your favorite contemporary art museum, what tasks would you have students do that connect to any of the high school math standards? Or is there any other math field trip you’ve planned to get kids out of the classroom? #mtbos #iteachmath

I had a great first day of school! I did this activity which I used to do a long time ago with my middle schoolers. I was afraid seniors might find it too basic but I learned so much about them! They had to tell me six facts about themselves using numbers. Here was my example…

Any high school math teachers in the US who do math contests with math club kids? Which one do you do? There’s so many to pick from! #iteachmath #mtbos

Last month the NYT said AOC "struggled" to give an answer on Taiwan and quoted her with "uhs" and "ums" to make her look stupid Yesterday talking about Hormuz Trump claimed he's heard from "numerous countries" and said "uh" four times. The NYT deleted the "uhs" and paraphrased him to look smarter:
NYT on Feb. 13, 2026:

The visit also demonstrated the relative foreign policy inexperience of Ms. Ocasio-Cortez, who has made a few overseas trips since taking office but does not sit on any House committees devoted primarily to world affairs. She struggled at times to formulate succinct answers at a nighttime panel session, during which she was asked probing and specific questions about how to respond to international crises.

Questioned about whether the United States should send troops to defend Taiwan if China invaded the island, she stalled for roughly 20 seconds before offering a substantive response.

“I think that, uh, this is such a, a — you know, I think that — this is a, um — this is of course, a, uh, a very longstanding, um, policy of the United States,” Ms. Ocasio-Cortez said, before saying that the country should try to avoid reaching that point with China in the first place.NYT on March 16, 2026:

On Monday, Mr. Trump claimed that “numerous countries have told me they’re on the way,” noting that President Emmanuel Macron of France would most likely help in the Strait of Hormuz and was an eight out of 10. “Not perfect, but it’s France,” he said.

Others are not demonstrating sufficient enthusiasm for his demands, he said.

Next yr I’ll be teaching a HS “math elective” class for kids who need to make up math credits. I can teach anything as long as it’s connected to the CCSS. Has anyone built a course like this? Any ideas of what would be most engaging for kids? Resources to pull from? I will have a wide range of kids…

I know a lot of people who use Duolingo. Teachers work their asses off to educate, foster creativity and independence and support your children as the individuals they are. I urge you to reconsider and let your money/data point do the talking.

We studied parabolas earlier this semester in 10th grade math. I visited the Very Large Array this weekend and showed this picture to my classes from space.com. Was very stoked that one kid saw it and said “Parabolic!” (Second pic is mine from one of the displays.)

Besides the IM curriculum for A1/G/A2, what are other good problem-based math curriculum for HS? Ones that follow the experience first, formalize later model. I also know of Math/Stats/Calc Medic. What else is out there?

Have any other public K-12 teachers in the US been dealing with district Internet outages this year? Today is the third time this school year my school has NO internet. I can’t even make hand written worksheets for the kids cuz we can’t log into the printers to make copies. 😭

Our school is having an issue with our small group of Rohingya-speaking students because we have no way to communicate with their parents. Rohingya is mostly a spoken language so we can't use google translate and the district has no interpreters who speak Rohingya. Anyone else dealing with this?

Happy birthday to French mathematician, physicist & philosopher Marie-Sophie Germain (1776 – 1831), known as Sophie. 🧪🐡👩‍🔬🎢🧮 #histsci She taught herself mathematics using books in her father's library and by corresponding with leading mathematicians of her day, including Lagrange, Legendre & Gauss, 🧵1
Linocut of Sophie Germain (a young woman in with a collar with bow, under a dark dress, with a ribbon tied around her neck, long hair with centre part, half tied up with a ribbon in her hair). She is printed in dark blue with her own words about Fermat's Last Theorem in her own script carved into her hair and dress). Behind her in lavender is a grid of Chladni figures.
