Trying to be more present here and so wanted to share my work in progress padlet on Diversifying the Mathematics Curriculum. I am also keen to come and lead assemblies for students and PD for teachers (free!) on this subject if anyone is interested!

I don’t suppose anyone has a scheme of work for AQA Level 2 Further Maths they would be willing to share with me? #MathsToday

Good luck to my lovely boy and all the students taking TMUA today and tomorrow. My son is focusing on enjoying the maths. He has been super lucky to be supported my @meimaths.bsky.social Problem Solving Matters course and also the new on demand course for TMUA ❤️

One of the absolute highlights of my job is leading on the mA*ths and Further mA*ths programme. Today I am at Imperial uni having lots of fun with complex number 😁

In #MathsToday I made 40 A Level teachers colour in representations of the binomial distribution.

This is your regular reminder that if you teach #ALevelMaths you should definitely try to join your local Maths Hub’s A Level Pedagogy group. There is some brilliant stuff going on all over England.

A quartet of representations of the binomial distributions. Screenshots from https://www.desmos.com/calculator/3ea50eafbc

X ~B (10, 0.4)
Shade the diagrams to represent the probability
P(3 ≤X <6)
and draw a numberline.

X~B(10,0.4)
Shade the diagrams to represent the probability P(3 ≤ X < 6) and draw a
numberline.

X ~ B(8, 0.7)
Which is larger:
P(X < 5) or P(X = 6)?

X~B(12,0.36)
P(X ≥ c) < 0.5
What is the smallest possible value of c?

X~B(10,0.4)
Calculate the interquartile range of this distribution.
What is the mode?

X~B(8, 0.7)
P(X ≤ a) < 0.1
What is the largest possible value of a?
P(X ≥ b) < 0.1
What is the smallest possible value of b?

X~B(12,0.36)
P(X ≤ a) < 0.2
What is the largest possible value of a?
P(X ≥ b) < 0.2
What is the smallest possible value of b?

Feels like ages since I have a proper London trip. Off to spend a couple of days with the fabulous HG Foundation and then Saturday doing one of the best parts of my job - leading at a Year 13 Further mA*ths masterclass day 😁 #ALevelMaths
