@Just_Maths Hi Mel, had a suspicious DM from your account 1 not sure if you’ve been hacked?!

@mathsjem @Just_Maths can anyone recommend some Casio. Calculator training for departmental CPD? Thanks in advance

@MsGHist White Rose Maths Trickiest year 7 group ever yet making good progress

Looking at a numeracy intervention package for KS3? Does anyone use one currently that is showing impact?

@BersekEv @grok is this true

En España los hospitales pueden sacar tu cama a la calle para que mueras lentamente si tú seguro privado no cubre los gastos. Lo siento, me equivoqué, es Estado Unidos... la tierra de la libertad de Trump, en España la sanidad es universal. Trump, tú país es horrible.

🚨BREAKING: Two researchers from UPenn and Boston University just published a paper that should be uncomfortable reading for every CEO automating their workforce right now. The argument is straightforward. Every company replacing workers with AI is also eliminating its own future customers. Laid off workers stop spending. Enough of them stop spending and nobody can afford to buy anything. The companies that fired everyone end up selling into an economy with no purchasing power left. Every executive can see this. The math is not complicated. But here is why nobody stops. If you do not automate, your competitor does. They cut costs, lower prices, take your market share, and you collapse anyway. So every company automates knowing it is collectively destructive because the alternative is dying alone while everyone else survives. The researchers proved this is a Prisoner's Dilemma playing out in real time. The numbers are already moving. Block cut nearly half its 10,000 employees this year. Jack Dorsey said AI made those roles unnecessary and that within the next year the majority of companies will reach the same conclusion. Salesforce replaced 4,000 customer support agents with AI. Goldman Sachs deployed a coding tool that lets one engineer do the work of five. Over 100,000 tech workers were laid off in 2025 and AI was cited as the primary driver in more than half those cases. 80% of US workers hold jobs with tasks susceptible to AI automation. The researchers tested every proposed solution. Universal basic income does not change a single company's incentive to automate. Capital income taxes adjust profit levels but not the per-task decision to replace a human. Collective bargaining cannot hold because automating is always the dominant strategy. They also identified what they call a Red Queen effect. Better AI does not solve the problem, it accelerates it. Every company chases faster automation to gain market share over rivals but at the end everyone has automated equally, the gains cancel out, and the only thing left is more destroyed demand. The one thing the math says could work is a Pigouvian automation tax. A per-task charge that forces companies to account for the demand they destroy each time they replace a worker. The conclusion is that this is not a transfer of wealth from workers to owners. Both sides lose. Workers lose income. Companies lose customers. It is a deadweight loss with no market mechanism to stop it on its own. Link t.co/AkgzBxi7jX

If you want to create a positive school culture where your pupils belong and thrive put staff first. If your staff don’t feel happy at work, are overloaded and unsupported then they won’t do their job to the best of their ability.

@MrAllington Absolutely incredible news

I can’t quite believe that I’m saying these words, but this is the face of a very tired, slightly delirious, but utterly elated, Deputy Headteacher who had just been appointed the substantive Headteacher of my lovely, lovely school. 1/7

@Headteacherchat We have too many ! Would prefer just one board.

Can anyone help Anon? I'm always fascinated by other people's staffrooms. What displays and ideas do you have?

Thank you @HughesHaili for an amazing CPD session today!

Victory at Arthur Terry Learning Partnership. After 9 days of strike action, with strong pickets across 20 schools, mass parent support and sustained public pressure, NEU reps and members have won. - Redundancies stopped. - TLRs protected. - Regradings blocked. - Term-time only changes scrapped. - EHCP and pupil premium funding protected. But most importantly accountability secured as the senior leadership has gone. This is the power of organised workers standing together with their communities. Congratulations to ATLP members and reps, and thank you to everyone who stood in solidarity. ✊

@robertkaplinsky This looks incredible thank you

I’m devastated. A good friend and dormmate of mine, Amin Pourfarhang, has been sentenced to death after protesting in Iran 😭 He’s one of the kindest people I’ve ever known. Please share. Visibility raises the cost for the Islamic Republic and may stop this execution!

@NABurkinshaw @cerysturner7 Teacher, my children have significant blood disorders and I need to have my phone incase of an accident, a nosebleed or a fall. There are circumstances where a phone is needed.

@cerysturner7 The staff thing is crucial. As is ensuring that exceptions are not made for eg students to take photos of the board, use a particular app for an activity, etc. There is a whole culture that needs to be undone.

NEW: Schools are now expected to be fully phone-free, the govt has announced. + Pupils should not have access to phones during lessons, break times, or between lessons + Staff also expected to not use phones in front of pupils + Ofsted will check schools are following phone-ban

To anyone interested in math and AI: Ken Ono, a renowned number theorist, has recently started posting here. He's definitely someone worth following.

@HughesHaili Sadly not in person.

You open an email about CPD and @HughesHaili is presenting! Very excited about the training day now.

I’m actually so devastated right now. I matched with this guy on hinge yesterday and we were having the best conversation I’ve probably ever had on that app. This morning was going to reply to his message from last night and in my half awake stupor I accidentally unmatched him and I cannot for the life of me find him anywhere!! Antony please, if you’re reading this I’m Sorry!!!! Imy

My name is Claire.. I was sitting in the waiting room for my first appointment with a new dentist. I noticed his degree on the wall, which bore his full name. Suddenly, I remembered a tall , handsome, dark-haired boy with the same name had been in my high school some 25-odd years ago. Could he be the same guy that I had a secret crush on, way back then? Upon seeing him, however, I quickly discarded any such thought. This balding, gray-haired man with the deeply lined face was way too old to have been my classmate. After he examined my teeth, I asked him if he had attended the same school as mine.. "Yes. yes, I did.' he gleamed with pride. "When did you graduate?" I asked. He answered, "1987. Why do you ask?" "You were in my class!" I exclaimed. He looked at me closely. Then that ugly old bald wrinkled gray-haired decrepit SOB asked, "What subject did you teach?”
