What's this? Oh it's episode 4 of #Un-NaturalNumbers With the magnificent @steckl.es and @paddymaths.bsky.social. Give it a watch if you're in the mood for Klein groups, Harshad numbers and Modulo 4 arithmetic. #mathstalk #mathschat #talkingnumbers youtu.be/RfNBjhHGJ54

Latest episode of Invasion of the Poddysnatchers is out now from me and @paddymaths.bsky.social, we watched Devil in a Blue Dress starring Denzel Washington and Don Cheadle from 1995. open.spotify.com/episode/29Of...

I've also expanded my collection of A Level Further Maths 'Exam Question a Lesson' packs for the new half term. Setting and marking three of these questions each lesson has been really helpful with Year 13 this year. (As you can see, I've become a bit addicted to the Sagona font family!)

I’ve ended up with a few spare lessons with Y8 (unknown for me, I’m usually behind!) so we’ve been doing investigations. They came up with loads of things I’d never thought of! I particularly liked one student’s justification of why even squares appear in square numbered rows. #MathsToday

In #MathsToday we will be playing lobster pots. I bloody love this game, and my version has become ridiculously complicated, with weather forecasts, pirates and extra places to go fishing. Here is a simple version: www.google.com/url?sa=t&sou...

Four squares. What’s the area of the blue triangle? #geometrypuzzle This is another of my all-time favourite puzzles. Written on a day when the weather was too bad to go outside, so it seems appropriate for today! How would you solve it?

One of the things we talked about yesterday was the importance of checking #ALevelMaths students know what makes a good sketch. So in #MathsToday I showed Y8 what good and bad sketches look like. I then plotted some graphs on @desmos.com and got them to sketch on MWB. Might as well start early!

A thread of silly videos I've made (most of which are over a minute long, so have to be posted via YouTube links) The final dance in Dirty Dancing, but they’re dancing to The Muppet Show theme tune. www.youtube.com/watch?v=V9v6...

My Parallel Academy offers free online maths tutoring for 250 students. Just recruited 450 more! Preparing bright state school kids for UKMT maths challenges. We need more superstar maths teachers/tutors who offer 8+ hrs/wk evenings/weekends, £27.50/h. Email CV & note to [email protected]

In #MathsToday I was trying to explain how to manipulate numbers in standard form so that you could add them. The class was properly struggling with the concept until one of the kids went, "one gets big, the other gets small. How is this even difficult?" 😂

Whammageddon! Got done by a year 8 watching TikTok on his phone. Confiscated the phone in revenge, obviously.😂

My Y12 class has been solving trig equations this week, and in our first lesson calculators were banned! Here are the new resources I made for using exact values: ✨Exact Trigonometric Values Sort It Out ✨Solving Trigonometric Equations with Exact Values Crack the Code #UKMathsChat #ALevelMaths

In U6 #MathsToday we're starting off with a concrete example of finding the values of a and b that minimise the sum of the squares of the residuals for our linear model. #ALevelMaths

In #MathsToday we were making Sierpinski Tetrahedrons (Green so they can approximate a Christmas 🎄 tree) These two quiet students loved it being called "Sir Pink C" They decided it needed to be a handsome hat. #ITeachMaths #MTBOS

Mission accomplished! Last school year, I was inspired by another post to curate and organize 180 math tasks on Google Slides. Here is the link: bit.ly/180daysmath

I'm #mathstoday we did some calculating b^2-4ac on whiteboards to iron out some negative number issues before using the quadratic formula to solve quadratics

Gradient-point-line structure #mathstoday #alevelmaths

Just finished differentiation with my #ALevelMaths students, and started integration. I'm reminded of this excellent xkcd comic... #MathsToday xkcd.com/2117/

In March 2022 I discussed a property of twin primes with Brady on Numberphile youtu.be/n4gmYjyI3vo?... Pick a pair of large twin primes. Multiply. Find digital root. It's 8. I seem to remember I was first set this as a puzzle by Colin Wright (though that's true of many a thing...)

An absolute classic for Y9 #MathsToday. I don’t think I’ve ever seen them so engaged on a Wednesday afternoon.

Teaching year 8 about polygons in #MathsToday and they were exploring why only some shapes tesselate. Using the Polypad online manipulatives was brilliant and they had a great time creating some "exciting" tiling patterns. polypad.amplify.com/p#polygons

I do it like this with Y11 students.

#CoreMaths #MathsToday Finding the median, lower quartile, upper quartile, mean, standard deviation, etc quickly using a calculator. The fx-991EX, fx-991CW and CG50 all have completely different menus for this, so it took 3 times longer to teach than it used to. Thanks, Casio 🙄

Excited to make by debut on Numberphile. Here's me talking about an "unprovable theorem" and some very big numbers. www.youtube.com/watch?v=0Le7...

An old favourite, for anyone who is at THAT stage of the term #ALevelMaths

In #MathsToday with year 12 fm #ALevelMaths we were doing integration questions from www.madasmaths.com - particularly enjoyed this one.

In #MathsToday, year 10 have been moving to an algebraic understanding of direct proportion. We'd done loads of ratio tables and work from graphs before introducing equations using @draustinmaths.com's worksheets to allow some scaffolded independent work.

A menu of integration at the start of #MathsToday for Y13. Classify by technique. Lots of good discussions. #ALevelMaths

To give back to my community, I have created a scholarship for 5 worthy students in Year 12 or 13 studying A-Level Maths/FM. Please share this with your students - the scholarship awards them with a @CasioMaths graphics calculator + £150! youtu.be/Cd7JFkhMp6Q?si… Please 🔁! @mathsjem.bsky.social

More new resources from Year 12 lessons last week (I really need to be more prompt with #MathsToday!) Two very similar fill in the blanks resources, one with more of a focus on area: ✨Sine and Cosine Rules Fill in the Blanks ✨Area of a Non Right-Angled Triangle Fill in the Blanks #UKMathsChat

Might seem a little early, but here's a few Christmas maths activities for various levels - in case anyone actually plans their lessons that far in advance! github.com/loopspace/Te...

Today’s poem celebrates Fibonacci Day. It’s called ‘Word Crunching’.

#MathsToday We explored transformations of logarithmic functions today. Started with this (old) Desmos activity. Next, I put out 10 printouts of log base 10 graphs and students had to determine their equations. teacher.desmos.com/activitybuil...

In #MathsToday we covered histograms. Here's a fun task I wrote - certainly got them thinking. A lot missed the all important 63 in the start of the question. (With thanks to @nathanday.bsky.social for his input in writing this) Downloadable version linked here: kshancock.co.uk/lessonresour...

Totally derailed my year 8 class in #MathsToday by looking at how many ancestors you have going back over 40 generations (sort of 1066ish). We used some estimation and powers of 2 to come up with an unbelievably large number. Main takeaway - "I glad they are not all coming over for Christmas"

Not a great day for my #MathsToday, as I've been off sick with a cold or flu or possibly the plague. However, I have these useful worksheets by Tristan Jones that can act as cover or homework. They are not revolutionary, but are a bit of a lifesaver for emergencies. www.tes.com/teaching-res...

That was awesome. Loved it Still singing Birdhouse in Your Soul on the bus. #TheyMightBeGiants

Off to see They Might be Giants tonight. Seems like it might be a popular idea. #TheyMightBeGiants #SurpriseQueue
