Content of the orange ones is weird... none of them get close to 40% even in "their own" age group. Would be interested to see, say "hit me baby one more time" graph, would expect it to be a lot higher in the orange category
A vital maxim in education is richer kids will generally be fine, but if you screw up it's disadvantaged kids that suffer.
On board with this *but* it depends on the purpose of what we are doing the multiplication for But if I wanted to multiplicate accurately I'd probably reach for the calculator
@adamboxereducation.bsky.social whilst I agree with a lot of the changes in the 2010s it’s a shame to hear NG describe grid method multiplication as a nonsense method. It’s grounded in understanding the structure of the maths and is based on an area model - the most concrete example we have.
100%... get rid of it!

My advice was "it may be worth an appeal to see if you get more leniency the second time round" Turns out I was right!
BUT LOOK - we have some many inequities in our maths exams: kids who get the more expensive calculators get easier marks, kids whose parents can afford frivolous appeals will have grades changed
However, I emailed the parent and said "you could give it a go and see if you get a more lenient marker" Behold, the grade has changed!
I appreciate these are wrong, before I get people suggesting I want marks for wrong answers again.
reviewed a gcse paper. my view was harsh marking but that i could see why dropped marks. one paper had 4 marks dropped for what I viewed as stringent reasons, such as fraction lines not going all the way across and 2hrs 45 mins being written as 2.45hrs.

#MathsToday Year 8 looked at Square numbers and used them to problem solve sums.
are you using a program for this or just in your diary or something? I've found coming back to school this year I fall back on "doing what is in my head" way too often
Nowadays there's no way I'd consider working at a school where the thing at the front of the room i couldn't write on with a normal board marker.

In #MathsToday, Year 12 and I enjoyed doing some Susan Wall tasks. I particularly enjoyed this one. We matched the graphs up, and then found the coordinates of all the interesting points.
aim with this sequence is guided discovery on benefits of both tests, so we literally go from "so why do I need the second derivative test?", to "so why do I need the first derivative test?", to "but the tests disagree!", to "so now I see the point!"
#mathstoday #alevelmaths I explored classifying stationary pts with yr 12 today I asked them to do a 1st derivative test and a 2nd derivative test for the following sequence of functions: y = x³ - 3x (❤️❤️❤️) y = x³ + 3x² + 3x + 1 y = x⁴ - 2x² + 1 y = x⁴ y = x²/4 + 4/x²
Surds today: using an area model to see what happens when we simplify a used! #alevelmaths
I got (19/30) sqrt2
I did the discriminant=0 on the psuedoquadratic quartic
Right. Term's started, so no daily area problem, but I'll try to post one every Monday... #MathsToday #ALevelMaths Find the exact value of the green area.
Is the etiquette to post answers or solutions?
Hi maths teachers. I don't suppose anybody would ever willing to share a lesson on telling the time on an analogue clock for year 7 (set 9 of 9), please. My laptop has broken, yesterday of all days, so I am in a bit of a pickle this week. Thank you in advance
So it took a while, but here is the write up of my MathsConf38 session - Breaking Up with Formulae: Ratio Tables are “The One”! Turns out starting a new job the same week as presenting, then a busy summer weren't ideal for getting this done before now! 😬🫣
It looks like there is an argument there for great at english implies great at maths, but not the other way round
Written feedback
found my school reports this weekend (yr 10 '01 and yr 11 '02) and quite frankly, coursework is an absolute joke. every report "improve your coursework" 🙃
This is set homework. There is additional work to complete on trust on top of that.
We set wednesday for the next wednesday every week. About 5 past exam questions on topics they are doing right now. Also dr frost on top of that. #alevelmaths
📌
Also I have FM on my timetable for the first time in 9(?) years! #alevelmaths
loved being back at school this week. am planning to #mathstoday soon as I have stuff to share, but basking in it right now
came on for about 30 seconds in the play off final
went to a @uni-of-warwick.bsky.social community engagement event in Nuneaton yesterday and there was this nice maths of Dobble activity. My kids made their own mini set (with 3 symbols on each card) from this diagram.
And comes back to, is this what we really want marks to be dropped for?
It's defined in the spec as something students should recognise as meaning initial velocity in mechanics
it's still a vector we had one lose a mark for not putting brackets round their coordinates... I'm OK with this! but i dont think describing graph translations has vector notation as an accepted convention, nor is it written anywhere that it is
However I acknowledge that good exam technique would have been to literally re-write the bit they were trying to show. My Q is "is this what we want our exams to be penalising?". I don't but maybe others do
On the mechanics one, it's in the spec that students need to understand that u stands for the initial velocity and can be given in questions without explanation. So u=0 is literally saying "the initial velocity is zero", i don't see how that isn't stating the original request
A vector has direction and magnitude and this has direction and magnitude. There is no mistaking its specificity. Your example is not equivalent, it doesnt have correct mathematical language and it isn't specific.
What's not correct about the translation?
That's not equivalent
Yeah, my argument is that "these are the conditions we are operating under but does it differentiate between students' aptitude in maths?" - i dont think i agree with the emphasis on what is being tested here
In other news, showing something begins from rest in mechanics, it's not enough to show u=0, you have to state "so it begins from rest" afterwards. I mean REALLY.
I'm led to believe it wouldn't have got the marks, yet I don't see the difference between this and writing in vector notation. fwiw I do the same as you but I feel like im lucky that I follow the whim of this particular examiner.
Disappointing that we see evidence of overly pedantic marking in AQA A-level again. Remember that these are kids' futures and if they miss out on a university place for writing "translation of +4 units in the x direction" instead of as a vector they still know what they are doing 👎 #alevelmaths
Inspired by the great previous work of @kerrydunton.bsky.social and because @themathsbazaar.bsky.social is only looking at progression to Edexcel A-Level maths I’d like to produce some transition matrices from GCSE to @aqaeducation.bsky.social Maths. I’m hoping to collect enough data to be useful
Yeah we can do this
📌
here to help! you reds!
Nope, so more likely to get the other teams in that pot too
You're correct that you get two teams per pot. In fact being in the same pot as Freiburg is slightly increased by being in the same pot as it's 2 in 7 chance rather than 2 in 8.
M "nest" is haunting
the twist here is it's always some reserve player who is no big deal leaving
those who write "*star player* says farewell as departure confirmed" headlines are earning a special place in the afterlife
Ha!
#mathsonholiday a roman dodecahedron at Corbridge
Yes youre right having done the maths, its a typo on the @neunion.bsky.social website
is there any reason why TLR2 payments have gone up by 5.5% whereas every other pay scales has gone up by 4%? I can't find any media about it #ukedchat @missmc.bsky.social @heymrshallahan.bsky.social
potential pitafalls; it gets compressed by the rest of the lesson It could be a fluffy end to the lesson They don't get immediate feedback
Oh I like this because It's not dependent on what happened in the lesson, ie if you didnt get as far as you thought you would It has all students in including the latecomers
do they invite? Or do all speakers make submissions?
you won't regret reading this for the black socks tip
I think its probably because the nadir of lots of other subjects is just copying stuff off the board
absolutely this and this also has repercussions for later achievement where Ss have a belief reinforced that "being good at maths" is doing everything in their head quickly
Don’t know any hard sources although AMSP have been working around the fringes of this for a while primarily around girls participation. Biggest single thing I’d suggest is holding entry requirements at a grade 6 and not raising to a 7 for a number of reasons some practical and some perceptual..
I think id err on the side of "it doesnt really matter" though... the property without a bath had other issues too and I think if other things were right it wouldn't be a deal breaker as you can fix these things
In laws got rid of their bath and we coped with it. However, we definitely were put off by a property that didnt have a bath when we moved house as there's a difference between coping and convenience. I'd get rid of our garage and I dont understand why it's seen as an essential
maybe this is the problem? anything generalist has been done you may disagree
Oh, this bsky.app/profile/blat...
Gcse results come out and you look at your QLAs and there's one topic that's coming out under the others. How do you react? #mathschat #mathstoday #ukedchat

bumping into maths on holiday 👋
once I bought a return but the wrong way round 🫠🤦
🧵 Next year my team have requested CPD on using tech in lessons. eg Geogebra/ Desmos/ AI. QUESTION 1. Can you help me by pointing me in the direction of good resources that will help me plan sessions for them on these? I’m not a technophobe but it’s not something I do enough either.
📌
also we need to stop avoiding problem solving with the lowest prior attaining Ss who are sick of being asked to remember procedures they cant remember
so thinking about the top Ss, we spend a lot of time teaching them detail on things that they can already do they spend a lot of time practising stuff they can already do now think about the bottom they spend a lot of time struggling and not practising what if we flipped that?
is "regularly" a definition for Ss, do they need it regularly?
All year groups?
probably should have just tagged @oaknational.bsky.social instead of aiming for a random Emma McCrea account(!)
2) it jarrs against my beliefs that pupil-teacher relationship is fundamental to success that you could have Ss moving between groups so regularly. it feels like Ss who are successful with one teacher could be disadvantaged by moving we have been burned by students moving too much in the past
bit i struggle with is 1) validity of assessment, if done regularly, and testing 'whole body' of mathematics to check it's the right move to make. so how regular should regularly be?
reading new @emmamcrae.bsky.social book and reminded that in that @beckyfrancis.bsky.social et al research about grouping from 2018, the hardest bit I find is the "retest regularly and move students between groups"
you dont have to be weird, to be wired
Oh my goodness, this is GREAT thinking
this is your "modern world" reminder that you probably don't need reflectors for a modern car when driving abroad, the car settings probably have a right side of the road mode on the menu settings. 👍
📌
so i wonder about the order of the columns here and whether function machine should come before the expression on original sheet I put it before because I wanted my level of learners to see the expression next to both models
I’m not sure about using for substitution, but been playing with the idea of squaring. Thinking about foreshadowing completing the square.
