I definitely find some students do that but I try to use some examples where that is PARTICULARLY horrible and Quotient is much easier to try and nudge them

Introducing Quotient rule with #AlevelMaths in #Mathstoday. Had to do a lot of set up differentiating using function notation beforehand!

Oo one of my year 10s managed to do it! What a legend!

Have just spent the last forty minutes trying to do the first one of these to no success 🙈 if anyone does it PLEASE post a solution haha

Sometimes but to be honest we usually just chat about the questions as a team

Yeah has worked well when we have done it! Has usually been additional to going through a few key questions. We also went through phases of confidence marking and then getting kids to focus on the "highest confidence marked questions" that they got wrong which was interesting!

We have tried doing it as a big Spot The Mistake exercise:
- Teachers do the test and answer each question wrong (hopefully using a misconception)
- we then photocopy that Teacher answered misconception paper
- students work in pairs to find all the mistakes (we did it as a competition!)

Doing some TMUA prep in #Mathstoday and came up with this question to get my #AlevelMaths students thinking about sketching graphs/integration questions

Thankfully not! Although I got a lot of "... Is that one just zero..."

Haha some of them did that one by doing cos(30-30)=cos(0)=1...

Working with Double Angle formulae with Y12 in #AlevelMaths #MathsToday

Can you guess which one they found the hardest?

Doing some thinking about Integration in gain time for #Alevelmaths. Having fun with reciprocals! #Mathstoday

Think this one works! Really fun #x^2-7x+10 challenge @ljohns6.bsky.social
#MathsToday

Got a bit carried away with inverse trig functions in #Mathstoday with Y12s... #AlevelMaths

Yup! Got 4Cot(x) a few too many times for that one...
And I will add those 1/(4cosx) types to the exercise!

That is a great point - I allowed cot(4x) - we aren't at the double angle formula just yet (so I shall revisit this then!) For now I should change the question...

Introducing reciprocal trig functions with some more Varaition Theory in #AlevelMaths #MathsToday

I wonder which one they got wrong...

Great discussion in #Mathstoday about how our students would solve this and how we could teach them to solve it efficiently

Using* the most cursed #ALevelMaths Formula in #MathsToday

*absolutely not using but fun as a hook for Radians Sector lesson with Y12

Can I be added please!

Small Angle Approximation with #Alevelmaths in #MathsToday - always like using Variation Theory to zoom in on possible misconceptions!

North London Forever after Arsenal are crowned Champions League winners. ❤️

Seriously. This image should become iconic.

Unfortunately the link isn't working! Shall we chat over DM?

I'd love them!

This extension follows on quite nicely too

Oh yeah that's really nice!

A "year 13" and a "year 12" method!

Harder Direct and Inverse Proportion with Y10 in #MathsToday - nice follow on from our work solving weirder simultaneous questions using substitution

This was unbelievably enjoyable to do and I would love to relive that first time!
