Geometry just needs to be two units:
* Yep, it adds to 180!
* Ok, but what if we cut it in half like THIS?

Nice! I think Knizia really put it well:
“When playing a game, the goal is to win, but it is the goal that is important, not the winning.”

New comic! Why write hundreds of board game guides when one piece of advice fits all? 😎🎲

Picard management tip: The truth is that sometimes you just won't know the right thing to do. You still have to try.

I think the term "college and career readiness" is an incredibly well-intentioned shift in education that has left many, many high school students disengaged + disconnected from their learning.
They deserve to learn things that have value + enrich their lives in the present—not just the future.

If you're looking for a Halloween activity to do with your kids or students, you can make a "Flex-a-ghoul"—this is a Halloween-themed hexaflexagon that I made. There's a printable PDF on my blog: divisbyzero.com/2022/11/01/h...

This past week was really challenging at times in the classroom—but at the same time, I kept reminding myself to not give into that challenge with my own actions.
Something that helped? Having some "uplift moves" in the tool belt as a teacher.
Here are four of my favorites:

A lot of people think that every international student admitted means one fewer spot for domestic students, when the opposite is more likely true - the tuition revenue international students bring allows public universities to provide substantial discounts to domestic students, improving access.

My favourite thing about the maths teacher community on Bluesky is #MathsToday. If you’ve not joined in before, I can really recommend it. Posting a highlight of your day is very uplifting!

In #MathsToday (this week) it's been Maclaurin series with Year 13 FM, quadratics with Year 12, and upper and lower bounds with Year 9. A couple of ✨new✨ practice strips made and added to the site - truncating numbers and using bounds to find a suitable degree of accuracy. #UKMathsChat #ALevelMaths

Today's quiz ended with a fun question for me to look at! Alt text: kids' drawings of penguins playing a sport! #teach180 #iteachmath
I encourage everyone to put something random at the end of a quiz. Sometimes only 1/3 of my kids do it, but I know they all relax a little seeing it at the end.

I have to say, it's so much easier already to teach with our school's no cell phone policy. Phones, earbuds, and watches go in a Yondr pouch. The kids are talking to each other a lot more. They use their down time wisely, & they use the 5 last minutes to be on task or to catch up with friends.

One of the logic puzzles my students are tackling this week as an early finisher activity are these 1-16 hidoku puzzles. Fill in the missing numbers so that each number touches the next consecutive number either horizontally, vertically, or diagonally.
