Islands are made up of pieces of land completely surrounded by beaches. This island has 28 km? of land, and 40 km? of beach. What questions could you ask about islands?

Islands are made up of pieces of land completely surrounded by beaches. This island has 28 km? of land, and 40 km of beach. a. What is the smallest possible island that has more land than beach? b. Can you make an island with the same amount of land as beach? c. Is the amount of beach always more than the perimeter of the land?

These are the first slides I made on Islands.

Playing Mastermind with my 6 year old inspired me to make this in #Desmos. I discovered I'm a lot worse at guessing than I thought! #MTBoS #iteachmath classroom.amplify.com/activity/687...

Super cool. Loved this game as a kid (and as an adult). Thanks for making this and sharing it with us all.

Are a few people ruining the internet for the rest of us? Why does the online world seem so toxic compared with normal life? Our research shows that a small number of divisive accounts could be responsible – and offers a way out

Platforms could redesign their algorithms to stop promoting the most outrageous voices & prioritise more representative or nuanced content

The internet is a powerful tool. But if we let it reflect the world created by the most extreme users, we all suffer. www.theguardian.com/books/2025/j...

Eleanor Duckworth's reminder: The more intensely interested a teacher is in a student’s thinking, the more interested the student becomes in his or her own thinking.

Corollary: The more a teacher just wants to see right answers, the less interested students become in their (or any) thinking.

Calling all Maths teachers!

What are some of your all-time great tasks for secondary Maths?

Ones that could have their place in any curriculum, one that should be studied in PGCE courses, ones that started whole new genres of tasks...
... or just ones you really like.

(see some of mine below)

Critical citizenry. In the age of AI, this feels important to me. Not deep dive, but enough to be thoughtful and critical about AI use in society.

Probability frequently gets skipped at both the middle and high school level due to an overstuffed curriculum and the “rush to calculus”

What is your thinking about why high school never modernized?

It undergirds a lot of modern algorithms, recommender systems, and AI. So, not to train future workers for the AI industry, but I think these topics are increasingly part of an informed (and critical!) citizenry in the age of AI.

I know some people are super jazzed about ‘data science,’ but a basic intro to graph theory, linear algebra, and probability seem increasingly important topics for high school mathematics, to me.

What do you think?

For anyone who wants to use it. ☺️

In the curriculum I’m building, I center the use of Habits of Mind and Habits of Interaction. “Listen to Understand” is one. And, yes, naming and teaching it helps a lot.

Anytime someone you know mentions using ChatGPT or any other genAI, say "you know, I read this article about how incredibly bad for the environment genAI is" and refer them to this article.

Hi @jlanier.bsky.social ! Is your 21st Century Math group meeting every day during the four week window? Or only certain days? And, if someone wanted to join for part of that time but not all, do you have an outline of what you’ll be doing at various points?

Iran Join Rick as he explores the most surprising and fascinating land he's ever visited: Iran. In a one-hour, ground-breaking travel special on public television, you'll discover the splendid monuments of...

In the spring of 2008, I feared America was on the verge of war with Iran — and, believing that it’s good style to get to know people before you bomb them, I made “Rick Steves’ Iran,” a one-hour special that could (and would) only debut on PBS. Sadly, this special has become pertinent again today.

Brendan is great. It’s nice to have such a thoughtful math educator at such a high profile university. We need more post-secondary math leaders like him.

Enjoyed hearing your perspective. My experiences match a lot of what you shared.

Are the previous ones recorded and available somewhere?

Maybe not a proof, but it seems to me like these second differences create some intuition?

Yeah, less formal. Just try a few small cases and see if there appears to be a pattern. I did this problem with my students back in the day and remember one of my students finding something (but can’t recall what)

You’ve probably already tried this, but I wonder what the function looks like for “maximum squares as a function of # of lines” for 4 lines, 5, 6, …
