I've started to share the GCSE and A Level knowledge booklets that I use in my teaching. I am constantly updating them so any errors, feedback or questions are welcome :) I'll add the rest to the folder as and when I've recorded their study videos! drive.google.com/drive/folders/…

any tried and tested methods/resources for teaching proof in year 12?Would scaffolding work when teaching proofs. I think proof is a way of thinking &the fact that every question can have a different starting point make it hard for Ss @mrsouthernmaths @Whitehughes @melissamaths

@tm_maths In fact, it doesn't matter what the first set of primes are: A: The only primes are 2, 11, 31. B: What about 2x11x31+1 = 683? A: The only primes are 5 and 13. B: What about 5x13+1 = 66? 66 = 2x3x11 2,3 and 11 can't be in my original list (remainder 1) Each is a contradiction

@tm_maths You can play this game forever to show that there are infinitely many prime numbers to add to your collection. It won't result in all of the prime numbers, but that's not the point. In either case, you have contradicted person A's assumption that there can be finite primes.

no matter how many videos I'm watching of it or resources I'm looking at, I still don't understand the proof of there are an infinite number of primes. It's something I can memories the steps for but don't know what's going on.

How do you set out your table of values? Discussed at dept meeting tonight. I've always used horizontal but vertical gives you the coordinates beautifully!

Q1 - Does your school run A level taster days/sessions for year 11 students, and if so what activities do you do with them? #mathscpdchat

@Whitehughes Quite! I was trying to come up with conceptually interesting approaches. Also played with using a circle inside the parabola, and using small angle approximations… not much luck there though!

@Whitehughes I just use integration 🙃 If I'm being really lazy, I let delta=1...

Is there a mathematical name for this kind of natural symmetry?

Teaching through booklets- is it the way to go? I like it in my classroom but all classrooms are different! Thank you to @GemmaHeald and @JamesRawlins90 for all the advice. So lucky that I have a team who have opted to test these this term to see if they benefit our students!

@Ridermeister So a quadratic will only have real roots if all the coefficients are real, and it’s Disc ≥ 0.

@Ridermeister Inequalities in complex numbers don’t work the same (need to compare magnitudes instead), so ‘non-negative’ isn’t really a thing Square root a im num, you get an im num Instead, if Disc=0 -> one repeated complex root; if Disc≠0 -> two distinct roots (both complex or both real)
