Can't help thinking of this. Our new song?! [Might need to tweak the words a bit.] www.youtube.com/watch?v=fJbx...

Opinions welcome!

What do we call the tax that you have to pay? Unfair tax?

In #MathsToday yesterday, a Y11 student wondered whether y = 4x + 14 would be the equation of a line parallel to the line with equation y = 2x + 7. [Where might that have come from? Could one class it as an 'intuition'?]

I've just had a glance at Twitter, after many months' abstinence. Wow it is nasty, but why have so few maths ed people come (and stayed) on BlueSky?

T&i or algebra?

Which is larger, 900,000 or 60,000? When it comes to immigration, it seems to be the second number.

- but I think you would need a more challenging question than that, to make a convincing case for the power of ratio tables!

- and what was so horrible about last night's #Newsnight is that they didn't provide space for the presenter or guests to pick up on all the crude claims and disinformation coming from the Reform representative

Labour has started to adopt the Reform formulation, "The British people believe...". At the very least it should be, "the British people – 1 believe...", as far as I'm concerned. Labour isn't going to defeat Reform this way. Instead, Labour will fragment, which might be ok in the very long term....

2½ heads. How many legs?

I bought this wonderful ex-Uni-Leicester-Library book for £1. What was the library thinking of?!

Inspired by Lyonel Feininger?!

These authors provide a useful taxonomy of proof schemes: Harel, G., & Sowder, L. (1998). Students’ proof schemes: Results from exploratory studies. In A. Schoenfeld, J. Kaput, & E. Dubinsky (Eds.), Research in collegiate mathematics education III (pp. 234-283).

#NotMyBBC This is Fiona Bruce's typically negative intro to Question Time this week: "Why is it so hard to keep prisoners in prison? Rachel Reeves, should she quit if she raises taxes?" The obvious answer: "We don't fund the legal system properly. Be brave, Rachel, please raise taxes."

In #MathsToday I tried to help two Y11 students with simultaneous equations. It was all very abstract and procedural, though. Should I use a WW Sawyer-type story, eg about the cost of cakes and buns but where the letters elide between representing objects and quantities (of the quality, cost)??

Wot?!

In #MathsToday (last week) a repeat-gcse student was successfully using socatoa to identify trig ratios - however, I got the impression that this very habit had prevented him ever forming a secure image (verbal or visual) of the ratios, so it was holding him back rather than helping.

#BBCnews 'Our BBC', leading the news each day with tales of The Epping Migrant Sex Offender

#MathsUntangle The blog has suddenly been discovered in China. What does it mean? Should I be worried?

What is this?!

Gulp! Beaten 4-nil. Maybe we do have join up with those other maths associations.

#MathsUntangle Probably the best fractions task I've ever written (at least I thought so at 4 am this morning....)

In #MathsToday I helped a Y11 student solve inequs like x2+2x–8 < 0, via graphs and factorising to find a range of values on the x-axis. We hammered out a procedure, but it seemed like a completely alien world, a bit like going through a latin mass. If she masters the procedures, what does it prove?

#MathsToday Working with two Y11 students yesterday, we checked to see whether 121 was divisible by 3. The division 121÷3 gave us 40 r1. I suggested we could treat the remainder as 1÷3 which proved to be very challenging.

In #MathsToday a Y11 pupil said she thought it would be easier to get a grade 5 GCSE on the Higher rather than the Foundation papers. Is there any truth in this??

Manager of a not very good team annoyed by the suggestion that it's not a very good team....

In #MathsToday I used the classic 'cream for 6 people' recipe task with a Y10 student. 'pints' threw him so I changed this to 'litres'.

It's German, Jim, but not as you know it

Think of a neat way of calculating the amount of 2-stroke oil needed for 5 litres of petrol to produce a 25:1 mixture of petrol to oil.

A morning spent in Tolworth. The first time I've been in Walking distance of the Tolworth Tower, which I've passed 1000s of time by car and which caused such excitement (second only to the Vickers Building (Millbank Tower) when it was first built in 1964

How is it that the malign influencer Charlie Kirk is described on BBC Radio 4 news merely as a 'conservative'

Look! I can get into Selhurst Park without a computer!

Does this mean 3 > 1 is not necessarily true as we don't know 3-what and 1-what?

#bbcR4 Rather than developing our understanding of architecture, as a way of influencing what developers get to build, this silly man wants buildings that merely satisfy the curiosity of a naive 14 year old.
