In my 15 years working with districts to help make high school mathematics JOYFUL, MEANINGFUL, and EQUITABLE, I have found quality curriculum can have a tremendous impact.
So, I've been working to make such curriculum freely available:

Though I would say that in more recent years I have steered away from always telling, I love how this really outlines different ways to "tell" and reminding you that there really isn't a dichotomy between telling and not telling. I think that this really sums up the gist of the post but read on for more "Some advocate “Never say anything a kid can say!”, pushing back against traditional transmission models. Others urge teachers to “Just tell them”, emphasising the power of clear explanations. These opposing directives leave teachers caught between conflicting orthodoxies. In reality, teaching requires both explanation and exploration" Curriculum Tags: All https://amiealbrecht.com/2025/01/01/stop-asking-if-we-should-tell-and-start-asking-how/
Happy New Year! And a new blog post as a treat (a week earlier than planned).
NEW Blog Post: ‘Stop asking if we should tell and start asking how’
Why does telling remain such a charged issue in mathematics teaching? Reframing telling through its functions rather than its form offers a way forward.
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: 9781032898353 pic.twitter.com/4XVlryIeSx
I like this because it reinforces the idea that mathematicians are not necessarily those who are the "best" at doing math but they are those who persevere when things get hard. Curriculum Tags: All https://bsky.app/profile/courtneygibbons.phd/post/3leiav6d3is2p
Back on Twitter, my most viewed tweet was a link to my "math pep talk"—a video I made for my students that now has 23K views 👀

There's a lot to expand on in that video, like structural barriers to success in math. But I'm sharing it again anyway.

Math friends.. any suggestions for a good video on Sierpinski's triangle? My next chapter is similarity and thought that would be a good Monday activity after break.

Need an application of the Law of Sines to talk about with your students? How about the construction of the @spherevegas.bsky.social ?

A fun math puzzle: Town A and Town B are 30 miles apart. If you drove 30mph from Town A to Town B, how fast do you need to drive going back to have an overall average speed of 60mph?

2025 is going to be a really square year, and also be on the lookout for this specific square date!

The latest OAMEtalks podcast features @LLB_315 with a preview of her members only webinar but don't let that stop you, there are some great resources that she talks about.
Perfect if you are talking about exponential relationships (you might have to talk a bit about why a black hole is a black hole though - hint you are going to be talking about super dense objects) Curriculum Tags: MCR3U, MCF3M, MAP4C https://xkcd.com/3033/
Chiming in on the highlight of 2025. Here's my https://t.co/ENqAid9wGu #79. How many are in step 9? What is the equation?
I gave this to my 8th-grade class for our usual VP routine, not expecting an equation. However, Ben tried something & yelled, "It works!" What did he try? pic.twitter.com/LBkUD8Xpxt
Given that next year, 2025, is the first perfect square year in a while, I think you may want to focus on the calculation 452 this coming year in as many ways as you can think of. Curriculum Tags: All https://bsky.app/profile/geometiles.bsky.social/post/3lea5s4pxi22x

Let's continue the countdown to 2025.
Today's 2025 Factor Tree Puzzle was inspired by Dr. Harold Reiter who presented on factor tree puzzles at a math teachers' circle workshop I attended.

There are some good comments in the feed and I like the way the steps are laid out for adding integers but the line that resonates with me is the last part of this: "Get students really comfortable placing positive and negative numbers on number lines.

NEW Blog Post: ‘Four ways of seeing education, and why "best practice" is a myth’
Why do educators disagree about 'best practice'? Understanding competing visions of education's purpose reveals why universal solutions fall short.

Looking for a fun, free winter activity to cap off the year? ☃️
With this new holiday activity in Desmos Classroom (using Polypad of course 😀), students can design their own winter wonderland! They’ll color snowmen, build their own snowflakes, and more. ❄️
Check it out: bit.ly/4ix92Ru
I wrote about how I use the @desmos.com data collection screen for a Fermi problem routine in my classroom www.edutopia.org/article/tips... and here is my Desmos collection of those screens: teacher.desmos.com/collection/6...
Any other Fermi problem fans in the #mtbos #iteachmath ♾️ community?
When I looked at this I thought I would just start with a brute force method but after one calculation it was clear I should look at something more logical. And yes, it was a non intuitive result but it made sense. Curriculum Tags: Gr7, Gr8, MTH1W https://x.com/howie_hua/status/1867334829991506197
In my latest Edutopia article, Stanford prof. Denise Pope points out the glaring problem with grades:
“The first thing kids would do is go to the back of the paper, look at the grade, and never read my comments."
