Inflation hitting so hard, it's affecting the percentages
A pretty entertaining gallery of misleading visualizations + discussion

Got to test something new in #mathstoday. Normally, to decide which transformation to linearise a data set, I'd just show a circle of transformations where each quadrant has the options listed. I recently stumbled upon Tukey and Mosteller's bulging rule and ladder of powers and it's /so/ much easier

I've discovered some people call it a convex angle, which makes some sense, although it suggests a reflex angle should be called concave.
Incidentally, did you know that angles that add uo to 360° are called explementary?

Giving a child a calculator too early doesn’t help them learn maths; it helps them avoid learning maths.

I've got an annoying stats problem at the moment relating to seasonal adjustment of time series about calculating seasonal indices over multiple years. It feels very niche, so any insights are appreciated #mathstoday #mathsconf39 #iteachmath #ukmathschat

A very short primer on mixing degrees of arc with degrees of angle for circle theorems.
#UKMathsChat #iTeachMath
Historically degrees measured arcs and arcs measured angles. This might feel uncomfortable but remember how we measure an angle today … with a protractor … measuring around an arc.

Hmm, vibes. Open up an arithmetic text from the 18th century then scroll through the old Regents exams on jmap.org. It's not like CCSS has changed math teaching in any real way.

Big day today with the release of the final Year 10 unit plans wrapping up the curriculum portion of the Year 9–10 Mastery in Mathematics project at Ochre Education 🎉
To give you a sense of just how big Year 10 Mathematics is compared to Year 9, let's look at the stats 🔍👀:

Did a couple of the main ones last night so the basic defns and suvat. Not carefully checked and the equations are "rough" but can put a bit more effort in / share the slides file if you want. The aim is to summarise the relationships for review/reflection, not meant to primary learn from.

Over the summer Duelling Mathematicians has had a bit of an upgrade.
Loads of new question types, game statistics, and design tweaks, but the same frenetic music and sound effects.

It's really the antilog table that I remember, based log(2) = .3 to great accuracy, so
antilog(.3)=2
antilog(.6)=4
antilog(.9)=8
antilog(.2)=1.6
antilog(.5)=3.2
antilog(.8)=6.4
antilog(.7)=5
antilog(.4)=2.5
antilog(.1)=1.25
This improves Fermi estimating from order of magnitude to 1 sig fig

I carry in my head a 1-digit log table, so
A. log(24×365)~1.4+2.5=3.9
B. log(60×60×24)~1.8+1.8+1.4=5.0
C. log(365×10)~2.5+1=3.5
D. log(60×24×7)~1.8+1.4+0.8)=4.0
So B is a clear winner
A. log(24×365)~1.4+2.5=3.9
B. log(60×60×24)~1.8+1.8+1.4=5.0
