THIS PAGE is nearly a microcosm of the Internet: it contains
nostalgia, mild intellectual elitism, and a sort of call to arms
all in one page instead of spread all over the place! But I
hope that, at least to some extent, it also embodies that other
important theme of the Internet: the lone voice crying out for common
sense...
Primary Maths: Where did the spirit of Adventure go?
“Divide fractions? I can’t divide fractions!” wailed
Jill.
“You don’t have to,” said Clarence, “you can
turn them upside-down and multiply.”
THE presence of Clarence is a giveaway that this is an excerpt from
Book 5: Clarence wears glasses, and only crops up in the last book in
the Maths Adventure series, where some really tricky concepts are to
be explained.
I can’t remember
the other “presenters’” names (if anyone can, please
email me) but I certainly remember Maths Adventure itself. It was the
maths book I used when I was a pupil at Alsager County Primary School
on Bankside Court -- not that this means much, as I believe the school
has since changed (a) its maths textbook (b) its name and (c) its
premises.
Changing premises must
have made a lot of sense (the Bankside Court buildings were, er, not
great, though the grounds [“Down the Bank”] were brill);
expanding the name makes some sense too (there are several other state
primaries in Alsager); but I can only think of one reason to change
from Maths Adventure. It was too much fun and must have
turned a disproportionate number of its followers into
mathematicians. Perhaps a concerted outcry was made by the Arts and
Applied Science lobbies.
For Maths Adventure
lived up to its name. Often (though not universally) primary school
textbooks are an Adventure into knowledge for their followers;
the best feature of Maths Adventure, though, was that it was an
adventure into very genuine Maths.
As the quote at the top
of this page shows, it wasn’t afraid to teach core arithmetical
skills along the way. (Incidentally, please don’t draw from that
one quote the inference that Maths Adventure was sexist. I don’t
remember that it was, though surely even if it had been it would be
easy to change.) But a lot of its pages were adventures into areas of
mathematics which don’t get taught formally until well into
secondary school -- and in some cases, far beyond that. I’ll
pick two examples of this which I can still remember, but there were
many -- and if you don’t believe me, try and get hold of a copy
of Book 4 or 5 yourself! I went to a good secondary school,
Alsager School, and in the first two years’ maths there
encountered no concepts which had not been in Maths
Adventure.
One example of very
genuine maths was a series of pages about “number
machines”, which were devices whereby, say, Jill could heave a
large figure 4 into the feed hopper, and if the machine were an Adding
Three machine, a figure 7 would emerge from the back end. Other sorts
of simple machines performed the other basic arithmetic operations,
and multi-stage machines produced by chaining these simple ones
together were encountered too. For all the simple machines, pupils
were invited to specify machines which would reverse their effects --
the opposite of an Adding Three machine is a Subtracting Three
machine, and the opposite of a Subtracting From Ten machine is another
Subtracting From Ten machine. And armed with this, pupils could
construct “reversers” for the multi-stage machines as
well, and work out what must have been heaved into a multi-stage
machine to produce a given output.
This is, of course, the
solution of linear equations. It’s algebra. But
it’s algebra looked at from its theoretical underpinnings of
functional theory and inverse functions; it’s algebra with no
x’s in; it’s algebra for primary pupils, and
it’s algebra that’s fun.
The other example
I’ll reminisce about was just one page, on which were drawn
three stone columns reaching up into some clouds (the graphic design
of these books, incidentally, was as wonderful as the content). On one
column was written 1, 4, 7 ... from the ground upwards; on the middle
one, 2, 5, 8 ...; and on the third, 3, 6, 9 etc. The columns went
about as far as the 50s before disappearing into the clouds. The
exercises were actually pretty simple: they were all about taking
numbers from two columns, adding or multiplying them, and seeing what
column you ended up in.
And what’s this?
Well, it’s group theory. It’s about the closure, or not,
of infinite groups under certain operators. This is strong stuff! Its
“proper place” is university-level maths, but here it is
presented so that primary pupils can do it: presented so it’s an
adventure.
At the time, of course,
I had no sense that it was called group theory; not even any sense
that it might be important; quite possibly whoever was teaching me
then had no idea what it was about either. But years later, when I
encountered group theory, I was able to say to myself, as it were,
“Ah! This is all about infinitely tall columns with multiples of
three written on them!” and gain an immediate head start over
friends who’d never had these concepts seeded into them at that
early age.
Which, sadly, was almost
all my friends. When I was 14 I moved away from Alsager, and since
then I don’t think I’ve ever met anyone who was taught
maths from Maths Adventure. I can only wonder why not.
A search on Alta
Vista for references to a textbook called Maths Adventure turns
up nothing, as does a search for its authors’ names (one of which
was so unusual and delicious to me at the time that I can still
recall them both: Jan Stanfield and Anna Potworowska). Or rather,
the searches turned up nothing before I’d written this page!
Does anyone still
use Maths Adventure? And if not, why not? Are there really even
better age 7-11 primary maths textbooks out there? Or,
as I rather fear, has the prevailing mood become that it’s not
worth sowing the seeds of university pure mathematics in a
mixed-ability primary class of whom, on average, only one or two
will ever need to know about group theory*?
If so, this is a
shame, and can only be a decision based on a lingering feeling
that mathematics can never be fun in its own right, that it is a
tool and there is no beauty or Adventure there. The elegance and
finality with which Maths Adventure dismissed this argument is
perhaps what has lasted in my mind from it the best.

Footnote
* This proportion was actually a
guess. If anyone has real statistics as to what proportion of the
English population gets Maths, Computing or Physics degrees, let me
know. At least two from my primary school class of 20ish did, and I
lost touch with several more who might have, but this may have been an
exceptional case. But then again, perhaps it was an exceptional case
because of Maths Adventure...
Ten years on
Since I first wrote this page, just over a decade ago, it’s caused me
a slow but steady stream of email correspondence. People from all over
the UK have written to me to say they too enjoyed the books, and some
(homeschoolers and teachers) have asked if I know where they can be
found second-hand. I don’t; a web search conducted nowadays using
Google shows Amazon listings for some of them, but they’re deeply,
deeply out-of-print.
Pleasingly, one
primary-school teacher emailed me to reassure me that, even though the
books themselves were no longer used at her school, the spirit behind
them was very much alive and informed the way they still teach maths
there. She also recommended an organisation called the Association of Teachers of Mathematics
for those interested in good and inventive teaching of maths.
Several correspondents
wrote to say they knew, or had met, the authors, and filled in a bit
of the back-story: Jan (the writer) and Anna (the illustrator) were
brother and sister, and although Anna has sadly passed away since the
days of Maths Adventure, Jan is still around, and, among other things,
runs a foundation and web
site celebrating the work of his late father, the Polish artist Piotr
Potworowski. “I can assure you,” wrote one
correspondent, “that life for everyone in Jan and Anna’s
world was as delicious and exciting as the books”.
Most pleasingly of all,
I recently had an email from Jan (Stanfield) Potworowski himself, with
appreciative words for the page (I’m guessing maths textbook
authors don’t often get fan-sites) and including the snippet
that he’s still keeping his hand in, preparing (at the time of
writing) a workshop for maths teachers in his native Poland.
