Factorial Fun Odds and Evens Had a fun time planning a one off hour lesson prepping students for the Intermediate Maths Challenge so we took a look at factorials, in particular looking at properties of their fac…

Finished by look at an absolute classic Maths Challenge question that is great for talking about patterns and generalizing - so fun!

Questions involving powers and factorials where students need to group things into odds and evens

Questions involving powers and factorials where students need to group things into odds and evens

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

Parametric Equations with #AlevelMaths in #MathsToday

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 πŸ™ˆ)

I made a very silly series of videos along these lines a while ago. Very fun very niche!

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...

Yup! Starting by sketching graphs (also great excuse to use the sliders on desmos) and then making predictions from question to question, leading to simultaneous equations and using the discriminant 😊

Series of questions where students need to find intersections

Series of questions where students need to find intersections

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

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!

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

05.07.2025 08:36 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

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

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