Finishing up Quadratic Inequalities in #Mathstoday with some tricky compound questions

A Year 11 student wrote this question as an extension in #MathsToday following on from the questions we worked through below 😮 Definitely will be a fun qu to give my #AlevelMaths classes next week!

Been teaching Quadratic Inequalities and Trig Graphs to my year 11s recently so put this together for them as a challenge! Will also give it to my year 12s and see how they do... #MathsToday #Alevelmaths

Doing an adaptation of @mrlevmaths.bsky.social's variation theory for Session 1 of "Developing A Level pedagogy" for GLOW Maths Hub on Monday 3rd Nov! Can't wait for it! And a plug for anyone based in Gloucs and Worcs and teach A Level, then sign up here: amsp.org.uk/event/73f968...

Looking through our upcoming year 7 lessons and wanted to teach commutativity a bit more explicitly so got to make some questions to get students practising in #MathsToday Anyone else seen any other resources for this somewhere?

Wrote a very quick write up of our session at #Mathsconf39 about using Variation Theory in #AlevelMaths including the PPT that we used. If you came to the session and have any feedback for us please do let me know here or via email [email protected] #Mathstoday chelekmaths.com/2025/10/23/m...

Quickly made this as an introduction to distance vs displacement in Mechanics for my Y12s in #AlevelMaths #MathsToday

Also wrote this as an extension in #MathsToday based on the awesome session by @mathsmuse.bsky.social from #Mathsconf39

Trickier Surds questions with Y11 in #MathsToday I love writing questions based on fun maths challenge qus and found these I wrote a while ago that I really like PPT on old blog post here: chelekmaths.com/2023/06/20/s...

Put this together for my year 13s in #Mathstoday when starting Integration by Substitution as I sometimes find the textbook questions a bit tricky to start of with when I just want them getting used to the process. PPT and some other questions here: chelekmaths.com/2025/10/10/i... #AlevelMaths

Got these questions ON REPEAT with my year 13s at the moment. Almost finished integration and these crop up basically every lesson in #Alevelmaths #MathsToday

Made this for my Year 7s and Year 8s tomorrow after @joausten.bsky.social's fab session on Number Sense at #Mathsconf39. Will be very interesting to see how it goes! #MathsToday

Had a great time at #Mathsconf39 yesterday. Thank you to everyone that came to @mrsteele314.bsky.social and my session - the collective "Oohs" when people came up with good questions were a joy. #Mathstoday

Looked at Factorials with Year 10 in #MathsToday Started off looking at odds and evens based on the Maths Challenge question in the bottom right. I always love using Maths Challenge questions as a starting point for planning - this one was particularly fun 🧵1/4

Did this with my year 13s in #Alevelmaths as a gentle warm up. Getting them to guess what f(x) and g(x) was and to find each area depending on their functions was less gentle! #Mathstoday

Made this Circle Theorems and Trigonometry worksheet inspired by interwoven maths @nathanday.bsky.social in #Mathstoday PPT and answers here: chelekmaths.com/most-recent-...

Haven't posted to my website much recently but just made a quick post collating together stuff I've posted here over the past few months chelekmaths.com/2025/09/24/r...

Parametric Equations with #AlevelMaths in #MathsToday Continuing to try and use Variation Theory to zoom in on possible misconceptions!

Excited to be running my first session at #Mathsconf39 with @seethelanes.bsky.social Talking about Variation Theory in #Alevelmaths and how fun it as a guide for writing series of questions! Here is a set I wrote in #MathsToday for my stats Y12s! (also the classic misspelling of Natan 🙈)

"Draw an animal using only right angles" with year 8 this morning Not much laughter for my "Serpendicular" joke unfortunately... #MathsToday

Differentiating inverse trig functions in #MathsToday Some discussion upon reaching the answer of 1 about whether there was in fact an easier way of doing this question... #AlevelMaths

Always like thinking about how to get students to do something tricky by slowly building up the skill - I hadn't seen many "easier" finding intersections questions so enjoyed making my own! #MathsToday #ALevelMaths

Back to school thinking of a fun little starter for Year 13s after a summer off... #ALevelMaths #MathsToday

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

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

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

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

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

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.

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

Doing some Origami with year 7s in #Mathstoday. Opened up the folds to see what shapes we created and to discuss what we noticed! Can you work out what the 3D origami is...

Chain Rule revision in #AlevelMaths #MathsToday - Last one caused A LOT of discussion

Was teaching Binomial Expansion this week and wrote some questions based on an old MAT question I liked! #Mathstoday #Alevelmaths

Trying to scaffold some Variation Theory style Logarithms Questions in #AlevelMaths #Mathstoday - Trying to work on students "self speak" - What they say to themselves in their heads as they work through problems

Harder Vector Geometry in #Mathstoday #Alevelmaths Always like starting with the simplest cases for using equating coefficients to answer these types of questions and then building from there! 3D next lesson...

Bar Models in #Mathstoday with @seethelanes.bsky.social - Fun to have time to plan deeply with colleagues!

Doing Loci and Construction in #Mathstoday and got to use our favourite maths tool - the tiny ratchet screwdriver to tighten every compass every time!

More work on Trig Ratios with Y12 this week in #MathsToday #AlevelMaths. Big focus on what should be positive/negative and lots of practice in quite a compact table which I always like!

Absolutely love the Maths Challenge and have been prepping my year 10s for the Intermediate so also did it myself this week to model some struggle! Silly mistakes were made but as usual I had a great time. youtu.be/y7nuP4cFapU?...

Trying to anticipate misconceptions with year 12s in #Mathstoday with a True or False activity. 2sinx/2cosx caught an unfortunately large amount of them out #Alevelmaths Any I missed? Worksheet at chelekmaths.com/a-level/

Really enjoyed teaching Trig Identities to my year 12s in #MathsToday Introducing CAST diagrams always fun #ALevelMaths

New! My 185th gems post. Ideas, resources and updates for maths teachers. 💎 www.resourceaholic.com/2025/01/5-ma... #mathstoday #ukmathschat

In #MathsToday we were slowly building up to harder Trig Modelling with Y13s by focusing on simpler and then increasingly difficult cases #ALevelMaths Love a completion table for A Level Maths so trying to make more this year at www.chelekmaths.com

Continuing to make increasingly silly and niche Maths Videos at www.youtube.com/@chelekmaths... Have wanted to do something Sporcle related for a while! Was fun! youtu.be/t9GCRBLsUck
