If any of you have been following my series on Simple #Orthogonal #Polygons in @Mathematical_A #mathematicsinschool, the final part in the May edition has a typo: on page 9, P(n) = λ^n should of course be P(n) → λ^n, as n → ∞. But I'm sure you'd figured that out anyway! 😉

@FreelancePhilos @BedtimeMath Sum of squares = n(n+1)(2n+1)/6.
11*12*23/6 = 11*46 = 506.
Even more fun with four-dimensional oranges. :-)

@mathsjem @Mathematical_A @mrbartonmaths @Mr_J_Maths And I thought it was just age catching up with me!

[Rob Kearsley Bullen @Rob_KB_ntu]

Anyone got any good sport-related graphs?

@ImpactWales Not my idea - the activity was presented by Michael Anderson in his #BCME9 session. I just took the picture! 😁

Inspiring stuff from Prof Paul Ernest #BCME9

I’ve been debating whether to share this infographic on representations in learning maths (an aid to thinking about how you might make choices to help clarify a concept). I’d appreciate comments/suggestions. (Disc and surround are independent.) #bcme9 #maths #representations

[Mrs Philips @MrsPhilipsMaths]

Absolutely staggering. What does that say for how they value teachers? Mutters in the room when those words were spoken. #BCME9 https://t.co/pjwo8WMxRE

[Further Maths @furthermaths]

From May the FMSP will be superseded by the Advanced Maths Support Programme (AMSP). We will continue to provide similar services and support to all state-funded schools and colleges in England as well as support for Core Maths. More details: https://t.co/bgskHXYGKP
