Would be great to see this adopted in NZ schools. This UK school is reporting at 21% decrease in their absence rate.

In the final celebration of GHS mathematicians' #NCEA successes in 2025, we today congratulate those ākonga who gained Level 3 mathematics endorsements. Ka pai, and good luck with your post school next steps. #Geraldine #NZ #maths

Today we celebrate the NCEA Level 2 endorsed mathematicians from Geraldine High School following their recent exam results. We can't wait to see what your hard mahi will bring you at Level 3 this coming year. #NewZealand #Mathematics #NCEA #Level2

#NCEA results were out a couple of days ago. We're so proud of our long list of #mathematicians who gained #maths endorsements at Level 1. Ka pai. #NewZealand

If my student already uses the grid/area to multiply or factorise, I’ll use this. I do like that the product of the diagonals is always the same. That’s fun.
Let's learn how to factor quadratics where the leading coefficient isn't 1 without guessing and checking.

(Okay I know that sounds boring but I like this video lol)

One of the coolest math facts that I know is that the only circle that fits perfectly in a 3-4-5 right triangle has an area of pi.

Here's how we can prove this.

It really doesn’t. Plato had a great answer to this problem more than two millennia ago. In the Theaetetus, he describes memory not as a storehouse or filing cabinet, but as a birdcage. Imagine, he says, that each of us has a cage in our minds filled with birds. 1/

I keep coming back to this. Just such a fundamental failure of everything that has been claimed about a "knowledge rich" curriculum. Teachers are demanded to have higher standards but this slop is what they put out as their big rewrite.

Geraldine High School #mathematicians continue to want to take their maths further. Yet again next year we will have more year 13s studying a maths course than any other subject #nz #maths #ncea #level3

The video links are public, so will work for schools who don't use Dr Frost too. Hopefully they might be of help to other teachers and students preparing for 1.4 across AoNZ. #ncea #maths #level1 #mathematicalreasoning #newzealand @drfrostmaths.bsky.social
@drfrostresource.bsky.social for anyone else in #NZ using Dr Frost maths, I've put together this spreadsheet linking to key skills and videos for our #NCEA Level 1 students taking the 1.4 exam. They'll be using this to boost their exam prep tinyurl.com/GHSMaths Any suggested improvements welcome

The only headlines written about this should be:

Trump: This is somebody nobody else can do. We will get the drug prices down… 1000% 600% 500% 1500%. Numbers that are not even thought to be achievable.

In #MathsToday we played this. A sneaky way to squeeze in some revision on multiples and lots of fun.

Weaker students can struggle with that, though, but a little tree helped. Cue maths teachers saying "I've always done it that way!" That's why you need subject specialists! 2/2

Another great day at #NZAMT19 with more Craig Barton - being asked to describe our school's use of Diagnostic Questions in another session with Craig in the audience was a wee bit nerve wracking - and more, incl. NZ's PIAAC numeracy steep decline & 2026's Frankenstein Y12/13 assessments #mathstoday
