Links and help from @theericklee.bsky.social @studymaths.bsky.social @howiehua.bsky.social @pwharris.bsky.social and more #MathChat #MTBoS #iTeachMath
So lovely to see @mathsjem.bsky.social giving a shout out to @draustinmaths.com whilst listening at #Mathsconf40!
There's also a few gems that were great reminders!
Sorry, was too busy trying to bbq on a poorly constructed bbq.
A maze made from banagram tiles with a Lego figure in the middle.
And today we made a maze for our Lego characters.
One day I’m hopeful we might actually play Bananagram.
Gave this warmup question to my class today. Students had to think carefully about the function and what x represents in each statement. Great discussions. @studymaths.bsky.social #ITeachMath #MathSky
All the tiles in a bananagram set arranged as a bar chart.
We’ve arranged all the Bananagram tiles into a bar chart.

MATHS TEACHERS!
We are expanding our team due to increased curriculum time.

Lovely, dedicated & supportive team.
Easily commutable from Leeds & York.
Happy to answer questions via DM.
Please share if you can.

Last summer was a close game between us. Now I don’t have a chance.
I imagine the gulf will widen for a few more years yet.
My 8yo is now significantly better at Dobble than me. Half-proud, half-annoyed.
Every year you impress me with this. I always save mine for spring bank treat.
It's that time of year when people prepare and share resources for GCSE maths prep. So much is out there for EdExcel and AQA, but there's little for OCR.
We're an OCR centre for foundation, and I'm wondering if there's a pre-existing community for this sort of thing!?
Yes, I think this is what I'm going with. I'll add some notes to the original slide for anyone else that uses it.
An alternative approach is to ask “what assumptions have you made [in finding the values]?”
Also, why not make it truly goal free?
Some pupils will need practice in naming the sides and angles. Some may move on and think about area and perimeter.
An example-problem pair asking if 3 lengths form a triangle. Q1: Can you form a triangle with 2, 8 and 10 cm? Q2: Can you form a triangle with 5, 10 and 7 cm?
Update: Just added a bunch more questions to the generators. This one is one of my favourites to ask.
There’s definitely some kind of correlation between being a maths teacher and knitting Yoda’s”

That’s exactly what I’m thinking! Let the teacher state that everything is as it appears in the diagram.
A diagram of a circle with a radius of 1. A right-angled triangle is drawn from the centre with the hypotenuse tangent to the circle. Above, a prompt says "What angles and lengths can you find?".
A rough draft of an idea for a goal-free style task.
I want it to be as clean as possible but need to add a few more details to make it mathematically correct in terms of all the right-angles in the diagram.
Any thoughts welcome.
Ha, that’s amazing!
It’s a nice task with young pupils but I also use it in Y9/10 when talking about Surds and Pythagoras.
I normally draw a diagonal on the square and point out the two triangles with equal areas if they get stuck.
A 4 by 4 square drawn on a grid with the instructions "Draw another square with an area twice as large."
A simple task, but one of my favourites.
How do you see it?
Already up!

He really is. It’s so useful every year.

A full skip being replaced with an empty one.
Watching my neighbours skip being replaced with a new empty one - I can’t help but think of Tower of Hanoi.
The April #ProblemSolving Calendar is posted & that's no fooling!!
Plus March solutions as well.
Share your working out & thoughts here or on the post.

If bored
6. Take any four digit number (making sure the digits are different)
1. Rearrange the digits from largest to smallest and subtract the same 4 digits arranged smallest to largest away to make a new number
7. Keep repeating this until you get stuck on a number
4. What do you notice? 👀
One of my top 5 four-digit numbers!
In no particular order:
6174
2520
3025
5050
1089
As my Best Guess folders gain traction, remember that whether they are called Predicted Papers, Practice Papers or Best Guess Papers, they are ONLY practice papers. Until Paper 1 has happened, there is no way to predict or guess what will be on Paper 2.
