One of my former patients who notoriously was not the most adherent to her home program sent this to me this morning & I feel like this summarizes at least a third of my patient interactions with teenagers. I now intend to use “is that deception” instead of raised eyebrows
Relieved our department just decided to spend the 50 cents per user it now costs to use @NZGrapher Well worth it! Will make time series so much more enjoyable. So spend it wisely @jakepwills 😛
Ah so that's what calculus is! Recommended reading. Especially the "Now any fool can see that..." #iteachmath @EllipticKiwi #mathschatnz. .
To add to your bag of teaching tricks. And more generally a tone to emulate. In particular thinking of you @MrFahlander
Unexpectedly solid math joke!
Pissed off by Trump’s Lysol “jokes”? That’s not just emotion, it’s mathematic equation at work. @darryldarryl_ explains: twitter.com/darryldarryl_/…
At least two spaces of maths wisdom (maths idiosyncrasies?) left... anyone in the NZ maths-twitterverse who'd like to add something? #mathschatnz @nzamt @elsubash @benhilliam @mathsmatter @AklMathsJam @EllipticKiwi
This has been been such a fun conversation! Thank you!! I took @MrFahlander awesome poster and added a second page for more comments. We still have a few more spaces to fill. Let's keep it going! #MTBoS #iteachmath tinyurl.com/ybvcfvdc
I want a poster like this (including the replies) #aklmaths #mathschatnz #aklmaths
I want to make a poster: (a,b) is a point, unless it's an interval. ^-1 means reciprocal, unless it means inverse. Order of operations is PEMDAS, but don’t take it literally. Nothing, a dot and x all mean the same thing, unless the nothing isn't anythingl What else??? #MTBoS
Check out this multiplication chart drawn to scale from @the_chalkface! This seems so intuitive. More info here: thechalkfaceblog.wordpress.com/2017/04/29/the… #iteachmath #MTBoS
Theorem: All positive integers are interesting. Proof: Assume the contrary. Then there is a lowest non-interesting positive integer. But, hey, that's pretty interesting! A contradiction. #mathjoke
Throwing an object at the same speed but different angles defines an ellipse via its maximum height

I want to creat a website to share all my twitter recreational maths puzzles, Cuisenaire resources etc permanently PLEASE would you RETWEET this😛 (getting feedback is essential) @RJS2212 @chrisdysonHT Would you like a FREE site dedicated to planning creative maths activities?
Of course....multiplication is associative!!
Yep, this is pretty cool.
Double @Toblerone! 🙂 Pretty cool how nestling an #AbsoluteValue FN inside another FN can, at times, produce duplicates. Why is this? 🤔 Created in the basic @geogebra #AugmentedReality app (#iOS). More info: geogebra.org/m/ztavstsw. @AppleEDU #ARKit #MTBoS #ITeachMath #math

Parabolas are just products of linear equations, part 2 - this time with annotations. Less awe and wonder perhaps, but possibly more helpful. Thanks for the idea @Mathowitz desmos.com/calculator/j9o… #mathschatnz #mtbos #iteachmath #desmos
Parabolas are just products of linear equations. Kicking myself for not having introduced them like this. Good thing there's always next year! desmos.com/calculator/tbx… #mathschatnz #mtbos #iteachmath #desmos
With the long weekend upon us, here’s something to look forward to next week: #MathsChatNZ reboots at 8:30pm, Tuesday, 4th of June. Put forward your ideas for our chat here: docs.google.com/forms/d/e/1FAI… #edchatnz
I had a great time yesterday at HOD with @rhysauck talking to over 30 HOD's about how to use our website bigdatasmallclassrooms.com to give students easy access to the world value survey. #amahodday2019 #mtbos #ITeachMath #mathchatnz
