Dramatis persona*
Helen Chick
I've always wanted a bumper sticker that said "I'm a female, LDS/Mormon, Scout leading, geocaching, pianoplaying, bicycling, mathematics educator with a PhD in maths ... and I VOTE"! I think this makes me a minority group of cardinality 1!
* Since there's only one of me and "personae" is plural (I think), I've gone with dramatis persona.

This is the post in which I attend a maths teachers’ conference and demonstrate my incapacity to identify and stop at a count of 12. That’s irony for you.
Last week I finally got around to getting myself a “professional” Twitter account for my work identity, so that I can join the large number of maths education […]
Today’s midlands trip was a day trip to Campbell Town, and the morning winter light and the fact that I had a few minutes up my sleeve meant that it was worth stopping at St Peter’s Pass to take a photo of the row of skeletal trees that march across a paddock by one of the […]

90. Triangle
There is, in every orchestra,
Kept with the xylophone,
A threeways folded metal rod
That plays a single tone.
Its primitive simplicity
Musicians might resent,
But does its artful symmetry
Make maths folk feel content?
Well, though they recognise its sound
And find it rather quaint,
Geometry’s definition says
A triangle it ain’t.

70. 67%
67% it says,
67%;
I’m sure it’s really 2/3, you know;
2/3 is what they meant.
The difference is really minute, they’ll claim,
So small, you’d think it okay
To leave out the last of the decimals,
But I’ll be angry all day.
The fact is that it’s a recurring one,
Don’t you deny it’s not:
And so should be written properly
0.666…
2, 3 […]
I have just seen something about “Integrating Differentiated Instruction”. Given the inverse relationship between integration and differentiation, surely “Integrating Differentiated Instruction” is just “Instruction + c”?
(This is one of those puns for which the size of an appreciative audience is likely to be rather small*. It may even be less than 2.)
* It lies within the […]
I have just spent a day attending a conference on sustainability in education.
This is not an issue for us mathsy folk as there is an infinite supply of numbers.
And we can […]
