it’s funny how proof by contradiction is both a concept students really struggle with and is also usually the easiest route

noSineRule Q1 An exercise in right-angled trigonometry. No Sine Rule required. No algebra required. Find an expression for the missing side. #UKMathsChat #iTeachMath
Absolutely: having a mental model of x, x2, 3x etc is the biggest barrier to algebra progress and substitution with algebra tiles is an excellent way to help.
Sam Blatherwick@blatherwicksam.bsky.social · 3w agofinally, I agree that we shouldnt stray far from numbers, which is why I think the first lessons should be around using them for substitution and the x-bar being exchanged for numbers
A few weeks ago, I posted a blog about following up worked examples by asking "What would happen to the answer if I changed the question slightly?" Here's another example of this from the blog. wp.me/p9t8DE-s8 #Mathschat #MTBoS #iTeachMaths #Maths
It's been nearly a year since I last published a blog about Mini-Whiteboards and how I feel about them. Since then, as a school, we have done lots of work on routines around our use of MWBs. Have a read of my 2.0 blog to see our Agreed Consistencies around this brilliant classroom tool.
whatever you think of this, tomatoes in the fridge is an act of wanton vandalism

This is a fab sequence of questions
Miss Morris@morrismaths359.bsky.social · last mo.#Mathstoday One of the things I find is in the lesson students can factorise. As soon as you mix up the questions they can't do it. Got my Yr10 to have a go at these and it was unsurprisingly how much slower they were.
Left over jacket potatoes. Sliced about half an inch thick. Fried. Always worth throwing a few extra potatoes in the oven for when you're having jackets.
Michelle@michelleroy78.bsky.social · last mo.I just want to give a huge shout out to whoever decided that potatoes can be included with breakfast.
I can't see how parent whatsapp/social media groups linked to classes/schools have any positives whatsoever
Last night, an exhibition I've been working on was launched at Cromford Mills in Derbyshire to mark 250 years since building of 2nd mill (blue print for cotton factories worldwide) and early industrial housing. It's open all weekend, with lots of activities. Critique my graphic design efforts!
gotta love recipes that require you to have the oven at a certain temperature "preheating" for nearly an hour before you need use it
Y9 enjoyed reviewing linear equations in #mathstoday with this from the legendary Don donsteward.blogspot.com/2012/02/line...

ideas and resources for mathematics teachers of 10 to 16 year olds

what if we taught reverse percentages first would students have a more compelling reason to engage with multipliers?
How do we feel about AQA penalising students who put 1x instead of x? 🤔🤔🤔
long shot but is there data anywhere on average a level maths class size? #alevelmaths
A pupil can reach the expected standard through strong arithmetic with relatively little success in reasoning and problem solving. But can they apply, reason, justify, challenge ideas and think critically? There’s a big difference between doing mathematics and using mathematics.
if the decisions we make prevent students from studying maths past 16 then we reduce the potential pool of future maths teachers.
If you have centralised resources that must be adhered to w/out deviation, are there opportunities for staff to craft learning in your school? or is this a skill you have to learn when you get a TLR? Or is this overlooked?
What's the worst possible score you can get on this solitaire game?
Ash, Blur, The Cure and Daft Punk decide to go on tour. They play 4 different venues, Aberdeen, Belfast, Cardiff and Dorking. Each night they rotate their venues, so Ash play in Aberdeen the first night and Belfast the next and so on... Daft Punk start in Dorking then go to Aberdeen and so on...
Went to the Escher exhibition today at Somerset House. Went to the wrong entrance by mistake, so had to go down the stairs. And down the stairs again. And again. And again. I'm sure it's a good exhibition! I'll get there one day, I'm sure! #MCEscherUK #mathsky
#mathstoday used A3 whiteboards for the first time @mrsouthernmaths.bsky.social ❤️
This is infuriating. Over the past ten or so years we have seen a marked decline in portion size. 6'2 teenagers getting tiny plates that are barely a snack. Fix that before this moral hand-wringing over what they're eating. www.theguardian.com/education/20...

Any edexcel markers on here? Did you mark F paper 1 … Q12a? The Asma cycling question …. I have a query?!? If you can help DM me please?
I’m pretty sure that by 1981 the government had stopped telling me what 2/6 was in new pence I think it shows 9-1 grades haven’t worked and they need to be ditched; only five grades are needed anyway
