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

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)!

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 a rectangle, hey wait a minute I can see 3 twos!" In an exaggerated surprised voice. Love this kiddo v. much, father son week while mum is away and moments like this are so special. #iteachmaths but in #mathstoday I was teaching this little man to explore...I know what I can do, he says.

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

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?

Interesting graph, so many questions. www.rts.ch/info/suisse/... Evolution of the number of federal civil servants per 1000 inhabitants

Very pleased to be presenting at this! I'll be talking about the wonderful world of generating functions. #MathsToday

He said, giggling: "I know it's 50, we don't say 5 - 2, that would be silly. We say fifty two"

In #mathstoday. When he's up for it it's the most special thing watching him learn. (My son at home)

In #MathsToday we were talking about Chekhov's gun (the idea that, in a play, if a gun is introduced early on then it must be fired at some point later) The Chekhov's gun in our question was that the area of a triangle was 8. We hadn't used it yet, so we had to figure out a way to introduce it.

In #MathsToday my kiddo beat me at SKYJO. He's 5 and happily adding up those negatives. Today I showed him pairs that add to zero. He has been counting to -2 since he was 3 because of the lift in our apartment block...

In #mathstoday showing the mean from a different perspective on @geogebra.org . www.geogebra.org/m/e9hp3wpw

In #mathstoday we will be looking at stats tests. This will be my starting point. www.geogebra.org/classic/jcgr...

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.

www.geogebra.org/calculator/s... @GeoGebra version of this one [email protected]. 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!

Error and bearings on @geogebra.org in #mathstoday www.geogebra.org/calculator/a...

snorkl.app/plans. #iTeachMath #MathsToday This looks interesting! Explain and receive feedback...

Make my last tip more dynamic by using A.x on @desmos.com #Mathstoday #iTeachMath www.desmos.com/calculator/j...

Equation of tangent in one line on @desmos.com. A small tip. #ITeachMath #MathsToday

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

Some opening slides to my trig intro in #MathsToday

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...

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:

Really interesting video from @theguardian.com on hidden inflation... #MathsToday #MathsTeachers #EduSky youtu.be/H2Z-FQtezCc

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...

Deciding whether the number of orange smarties in a pack can be modelled with a binomial distribution on the Teaching Statistics 1 study day

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...

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...

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...

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!

@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...

In #MathsToday we added sites to our Voronoi Diagrams. Open the link, export an image and use it as a worksheet for you #IBMaths Classes. Really makes you think about the sequence of an explanation. Not updated with easier coords and eqs to calculate.

About to hit a major milestone in life. No doubt I will miss it during my tired commute tomorrow!

NEW: Graph Paper resource. It's been on my to-do list for a while but a recent post from @cantabkitty.bsky.social encouraged me to actually tick it off. Here's a short tutorial: youtu.be/g44d9BiwkAM And here's the resource: mathsbot.com/printables/g...
