Ah! I wondered how that question could possibly be worth only one mark, as the correct answer should be worth at least two!

We moved away from FM1 and FM2 as the grade boundaries were higher for that combo (this was 2019 - not sure how much of a difference there is now). FM1 and FS1 is - for us - easier to staff, grade boundaries seem fair and doesn’t disadvantage the anti-mechanics types 😁

Maths - graph sketching and a bit of series work. Further - investigating polar graphs 😁

Yeah - we are edexcel, but my students do not like salt water concentration questions! Dead rabbits are just simultaneous equations …

I have 29 in my year 12 FM group (big every year but this is unusually big!) and I do find it makes questioning more difficult. I try to develop their thinking through class discussion, but few volunteer. I’m doing more paired thinking time when I need them to figure something out!

I’m expecting a big vector question… as you say, a fair CP1

Ah, but I bet they redeemed themselves by doing the induction question using standard results 😬

Oh, that is fantastic! What an excellent idea 😁

Ah - my IT literate colleague said that the French version has been out for ages, but the packaging for mine made a big thing of ‘uk spec’ so maybe they’re different. Anyway, would have struggled to find it, so thanks!

Well, yes, it does then look much more like the working I’ve been putting on the board for the last twenty years!

Thanks very much for this - on mine it seems to be catalog - distribution (B) - inv normal (2) rather than 9 and 7, but now that I’ve found it that is pretty quick!

Thanks - I will have a play, but I think the reverse engineering approach looks less painful! 😁

Have you found the inverse normal function? Any help gratefully received! 😆

At this point of the course every year I end up in a conversation about how Mr and Mrs Maclaurin came to name their son Colin. Always seems an unlikely choice…

In #ALevelMaths with y12 fm we investigated the area of a shape under the general linear transformation with matrix elements (a,b,c,d)- nice to see the penny drop re effect of determinant 😁

Very sensible - I did like the old S2 questions which asked for the true significance level of the test, and you had to find the exact size of both tails in the critical region. Better way of asking the question!

Interesting - thanks. Edexcel here, and I do recognise the posted markscheme 😁

(Off to SLT to discuss this - I have done it at lunchtime for fifteen years, and I am tired…)

It does seem odd to double the probability with a binomial distribution, though, since the distribution is not symmetrical- you’re effectively lumping the known tail in together with a tail of unknown length (known area!) at the other end of the distribution

Wow - that’s great!

Well, I haven’t, but that is a great idea 👍

I talk about the film Cars and how Lightning McQueen learned to ‘go right to go left’ 😁. To integrate lnx you have to differentiate it…

Sounds good - do you do this in timetabled lessons or is it a lunchtime / extracurricular thing?

Couldn’t agree more 😁 but their first question when presented with some factual knowledge is ‘is it in the formula book?’ so I do have the conversation

Yup. Four strips means five ordinates - not the most difficult concept they have to grasp 😆

No, it’s the same as your photo. It’s the use of h=(b-a)/n that confuses them - even though they know perfectly well what the ‘width of each trapezium’ is 😁

Edexcel formula book beef: I have to teach the trapezium rule twice - once so it makes sense and again to match the notation in the formula book..,

FM students are pretty good at integrating sin squared by the time we’ve finished polar areas 😁 but the normal mathematicians need to see it regularly!

These are tricky - and I’m never sure whether they’d be given the substitution or not. It’s another one of those areas where FM students have a huge advantage as they do so much more with trig / hyperbolic substitutions 🤷🏻‍♀️

I have bought some of the ‘crayons’ but haven’t actually dared give them to kids yet as I think they’re not going to approve! 😁
