We use these as an intro into these kinds of questions, slowly builds up difficulty so students can practice the process on ones that aren't too crazy!

Big discussion about "negative area" and the differences between each of the answers!

Ended up teaching median from a Histograms in #MathsToday to my Year 11s - one of those #AlevelMaths topics that sneaks into GCSE. How does reflecting the Histogram affect the median...

Worksheet where students need to describe a new function after a transformation has taken place
Finishing up transformations of functions with Year 11s in #Mathstoday Students were struggling with describing functions after the transformations so made this to practice it and then will try it out with A Level classes later

Worksheet where students need to find the range of different functions and then need to find functions of their own given the range
Domain and Range with year 13 in #MathsToday #AlevelMaths - lots to discuss on the second part of this worksheet!

We live streamed the second half on YouTube which made for a very very unexciting video but definitely added to the fun of it all

Some of our wonderful department finishing off our Mathsathon at 10pm last night! We had spent the day at work doing 100 GCSE Higher Papers as a team to raise money for Movember. Was unsurprisingly very silly but very enjoyable.

Mock Time for year 11s so also a fun time to make resources based on topics they struggled with!
Wrote a post about it here: chelekmaths.com/2025/11/19/e...
Some nice questions were made on the way #MathsToday

Integration by Substitution
I always like using simpler integration by substitution examples to start of, things that students know how to integrate already that we can then use substitution to do before moving onto trickier โฆ
I wrote a bit about it here! I always like doing reverse chain rule first and then showing how you can use substitutions after (like how you can use substitution to differentiate with chain rule although we usually teach it by some sort of INSIDE X OUTSIDE thing too)

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?
