@adamboxer1 Except for the fact that this is the method used by computers for calculating gcds (with various efficiency tweaks), and that lies at the heart of one of the major cryptographic protocols used for the Internet...

need to find the greatest common divisor of two numbers? just fold them on top of each other until you can't any more!

GENUINE fact (not a "bit"):
The date is 5^2 / 3^2 / 45^2
It is probably the last time in your lifetime where all three numbers are square (the next one being 1/1/2116)

MATHS TEACHERS: If you’re seeking ways to add quirky ‘real world’ maths to lessons next year I’ve updated my blog index robeastaway.com/blog/blog-index . You can use it to find odd applications of (say) quadratic equations. It’s the sort of thing you might use as a lesson starter (1/3)

Edapt do what unions don't - focus on the teachers and the policy updates that affect them, rather than the political infighting and causes unrelated to the classroom.

@adamboxer1 @dare_richard I would probably follow with something like "Now everyone, returning to the question of..."

Ahhh I think this is my new favourite scenario. Super tricky one to deal with. What would you do next?

@adamboxer1 I sense that his use of the word "fun" here doesn't mean "colouring in silly pictures" or the like, but rather having fun playing with ideas, being in an open state for learning something - the second half about "the pleasure of finding things out" illuminates the first half.

@rob_fletcher_ @adamboxer1 More significantly, the time wasted doing this could be used for far better purposes such as lesson PREPARATION (TLAC Technique #1)

@adamboxer1 Could reduce workload overnight if schools/DfE sorted this

The amount of planning and curriculum development that schools up and down the country are doing is a national travesty
a colossally bad use of national infrastructure and resources
Tes magazine@tes
Almost nine in 10 secondary school teachers are developing their own curriculum resources for lesson planning, according to a survey tes.com/magazine/news/…

Sparkling with wit and fascinating real-world examples, @d_spiegel's THE ART OF UNCERTAINTY is an essential guide to navigating uncertainty while also retaining the humility to admit what we don’t, or simply cannot, know. In stores now. wwnorton.com/books/the-art-…

It was a delight to visit @totteridgeacad yesterday and to imbibe the atmosphere. Amazingly focused, purposeful and calm lessons, engaged students, and enthusiastic staff. Thanks for the warm welcome, and I look forward to incorporating some of what I learnt in the near future!

Super blog from @stoneman_claire.
Techniques are tools. Alone, they don’t make a teacher better. Excellent CPD focuses on giving teachers a coherent *strategy* in how & when to deploy techniques. Teachers must understand the ‘why’.

@TeachBeech2 Congratulations! If you haven't come across them, @mrbartonmaths has an excellent podcast (>200 episodes now) with lots of them being focused specifically on secondary maths. Ollie Lovell hosts another podcast (see ollielovell.com), though it is not particularly mathsy.

@StellaDudzic 10.35 is probably understood as a date: it's 0.35 of a day into day 10 of Excel time (perhaps starting from 1 January 1900). 0.35 of a day is 8 hours 24 minutes! Entering 10:35 with a colon should do the trick!
English
I thought I could use spreadsheets but I have formatted cells as hh:mm and entered 10.35 and Excel thinks I mean 08.24. Why?? I'll just have to remember the cells are times for myself.

@adamboxer1 😂 Though I did once have a student in tears because the exam went so badly, and they were astonished to discover they had got the top grade when the results came out. Definitely the exception, though!

Am I the only one that gets a bit nervy when students say their exam went really well?

I love my new school, especially the people I get to work with. If you’re a skilled maths teacher who is ambitious for their team, and would like to work in one of the most supportive and friendly schools in London, get in touch! tes.com/jobs/vacancy/s…

@MEIMaths I'm so sorry to hear this - she was a fabulous teacher. I learnt some wonderful things from her.
