Though I understand why, I am still disappointed at how the math community on Twitter fell apart. Despite that I have still stayed active there and created accounts on other platforms. I never really clicked with any of them but it seems like the math community on Blusky ( @davidpetro314.bsky.social) seems to be growing and a math community is building there again. So I'm gonna stick wth Twitter but try to participate on BlueSky as well. One of the things that I like is it's a little easier to follow hashtags. That was always my favourite way to be on the socials, following hashtags rather than people. That way you could always expect that that post was going to be relevant. On Bluesky, they are called Feeds and two that I follow are #iTeachMath and #MathSky.

My favorite slide from one of my favorite talks at @NCTM. One of the biggest challenges facing math teachers (whether they know it or not!) is turning wrong answers into learning. Behold! The Super Wrong, Kinda Right continuum. /by @ottensam https://t.co/r6VuU0AY5t pic.twitter.com/BNTOu6JVEV

Dealing with distance time graphs? Then this resource might be for you (and your students)

In our new resources on Distance-Time and Speed-Time Graphs, we have included many visualisations to help students to grasp the different features of these graphs.

You can find them linked below @DrFrostMaths:

Earlier this year the wodb.ca site went down but now all of the resources have been hosted by @TriangleManCSD on his Talking Math with Kids site

It seems simple but I think a nice way to have kids get into solving equations is to do a set of problems like this.

I made this towards the end of our topic on quadrilaterals (and they had previously done circles). Pupils always need more practice of working backwards, and this worked well: the difficulty ramps up nicely. Worksheet with answers is at https://t.co/olfodqTsYL pic.twitter.com/TlYjGnTSgL

In high school, I didn't realize completing the square literally means to complete the square. Here's what I mean: pic.twitter.com/lSAt0uwV5q

A neat puzzle-

1. Shade any 2 sections
2. What fraction of the square is shaded?
3. What other fractions are possible? Impossible?

This puzzle kicked off discussions at a workshop for PD Hub members. pic.twitter.com/u7i18u4cTa

I always used to start my lesson on squaring binomials with this but extended it to the form (n + a)² = n² + 2na + a² and would start by asking kids for whole numbers close to 50 and I would square them in my head before looking at the algebra that showed why it worked.

I appreciate that @JennaLaib continues to add to her collection of slow reveal graphs and I also like the reminder that we shouldn't steer away from controversial topics. Check out some of the new graphs including the one on the correlation between gun deaths and gun laws.

If you are playing with prime numbers then this is neat. 561 is a not a prime number but by over 100 different prime tests it comes up as prime.

"561" is an interesting number. It gives a "false positive" to these 102 prime-number tests: https://t.co/35N3bE1DSL pic.twitter.com/FMet8xJYT6
