Sion, Switzerland. Sorry about the light I couldn't take a better photo unfortunately.

#Claude made me this: Type I and II Errors. It took minutes.

Dr Jason Murphy @mathstweetcher.bsky.social · 27/01/2026

In #MathsToday, I used Claude to very quickly generate some questions with exact trig values in response to a student's question. He needed a way to practice beyond simple recall. I tweaked it a couple of times to remove supplementary angles, that is limit to 30 45 and 60, I also asked...

I added a display about #mathematics #books. It's a look into my bookshelf at home, but importantly, it encourages the students to read about #mathstoday... www.jmaths.xyz/posters/books/ There are many more out there I didn't include, so feel free to tell me your favourites, and I'll add them!

#MathsToday I made a bunch of posters for a maths timeline, check them out, personalise and download here: jmaths.xyz/posters/math...

Check out the Women in STEM posters from ingenium! Printed on high quality paper, they look great. Thisnisnjist a selection! womeninstem.ingeniumcanada.org/posters/

Composite functions anyone? I like to share this one each time I use it. Here's a dynamic version on @geogebra.org www.geogebra.org/classic/hf2k...

When did this happen?! @desmos.com . Finally, and it looks so nice too :)

The claim of 30000 combinations in Cold Rock Ice Cream doesn't feel like a lot, does it? Anyone want to do the combinations for me?! I wonder where that comes from. 6CR is already 38760. #MathsToday

Dr Jason Murphy @mathstweetcher.bsky.social · 15/07/2025

In #mathatoday I read @kityates.bsky.social and the kiddo was introduced to decimal numbers at the pool depth. He stood at what we assumed was 1.6m (another linear scale Kit)!

Dr Jason Murphy @mathstweetcher.bsky.social · 27/06/2025

On LinkedIn I shared a project for our project week. Plat Diviseur. Applied mathematics at a moment of expertise, the students can measure angles and divide and therefore in year 8 they put these skills into practice (with a little about constructions too)

Wow. He's trying to draw arrays in the mirror. 😍 #mathstoday

Dr Jason Murphy @mathstweetcher.bsky.social · 19/06/2025

It's used in IB, this is a question from 2021.

Dr Jason Murphy @mathstweetcher.bsky.social · 16/06/2025

Family fun. Sometimes I wonder if I am cheating the system. What about the kids who arrive at school who haven't played with mathematics very much? Do I contribute to a disparity and raising of an artificial bar? With time being squeezed at schools, how can we promote more of this home?

Building a fort with the kiddo and stopped to take a photo for #IBMaths students exploration ideas. Thinking about the angles required in those joints.

Dr Jason Murphy @mathstweetcher.bsky.social · 14/02/2025

www.geogebra.org/calculator/s... @GeoGebra version of this one from@corbettmaths.bsky.social. I'm not happy with the way I changed both the angle and side at the same time. My Friday brain not working out the logic to separate it!

Dr Jason Murphy @mathstweetcher.bsky.social · 26/01/2025

For graphical thinking, sometime shortly having done the quadratic discriminant I like to give a question similar to this. Determine k such that f(x) =k has 0,1,2 sols. Ignore me though if it's slightly off track, or you have something similar. This was IB exam Q inspired too

010

Dr Jason Murphy @mathstweetcher.bsky.social · 26/01/2025

And this, it comes on the back of similar work to yours I have for functions at IBDP.l, as we move to composiye functions. We get these tables in exam Qs (with derivatives too).

Dr Jason Murphy @mathstweetcher.bsky.social · 26/01/2025

Like it. In case this is of interest at some point, I'll leave it here.

In #MathsToday #iTeachMath is used this on @geogebra.org www.geogebra.org/calculator/d... Still exploring the link between f(x) and its derivative graphically

Rounding fix, just add dots ;) ...

Dr Jason Murphy @mathstweetcher.bsky.social · 20/01/2025

A little introduction to the ratios that have a special name in #MathsToday. Which other side lengths give the same ratio? What other ratios could we look at (link to @standupmaths.bsky.social new book, great stuff.) What's going on with the rounding here? www.geogebra.org/calculator/a...

Dr Jason Murphy @mathstweetcher.bsky.social · 20/01/2025

In #MathsToday. What is the equation of this line, what do you need to know? Hidden behind this is a cubic function, derivatives for more precise function and the coordinate to be shown:

Dr Jason Murphy @mathstweetcher.bsky.social · 17/01/2025

This just came to me, it's how I spent 20 minutes on my Friday night—the things we do for #MathsToday. You can't help but look at the y-axis to judge it... www.geogebra.org/calculator/a...

Dr Jason Murphy @mathstweetcher.bsky.social · 16/01/2025

In #MathsToday I wanted to highlight a particular domain when comparing functions with their derivatives. I made this on @desmos.com www.desmos.com/calculator/k...

Dr Jason Murphy @mathstweetcher.bsky.social · 13/01/2025

I always enjoy a @standupmaths.bsky.social book. This one is no different and my #mathstoday is on in the car. My recent contribution to the triangle world, sharing this with students: "Because of the steep incline, the cabins hang from eleven-metre-long arms" www.swissinfo.ch/eng/swiss-ma...

Dr Jason Murphy @mathstweetcher.bsky.social · 13/01/2025

In #MathsToday we were looking at exponential graphs, in particular the asymptote using a point on a function and an associated table of values. Students replicated the process on their TI-nSpires. www.desmos.com/calculator/o...

Dr Jason Murphy @mathstweetcher.bsky.social · 09/01/2025

In #MathsToday I genuinely used @geogebra.org as many times as I have posted. In this example a student was interested about what differentiation was so I knocked this together live. Turns out I randomly picked a very nice function to illustrate it. New to GeoGebra? try to recreate it!

Dr Jason Murphy @mathstweetcher.bsky.social · 09/01/2025

Followed by something more standard for #MathsToday: (On A @geogebra.org spree this week) www.geogebra.org/m/mx4qqb7s

@geogebra.org It is great when you can build on others' work. I nicked this from the University of Adelaide and made the ones and zeros S for success and F for Failure to introduce BinomDist. I am hoping students will appreciate me not asking for 5 trial trees! www.geogebra.org/classic/bzt4...
