Curriculum Update
Development of new Mathematics and Further Mathematics AS and A levels for first teaching in 2017 continues. The report from the A level mathematics working group has just been published, focusing on areas of mathematical problem solving, modelling and the use of large data sets in statistics. It contains expert advice from group members on how these key aspects of the new content could be assessed and provides examples of questions. Ofqual’s open consultation on subject-specific rules and guidance has also just been launched, seeking views on:
the revised version of
the assessment objectives
the proposed approach
to regulating new AS and A level qualifications in mathematics and further mathematics;
the subject-specific
Conditions requirements and guidance Ofqual propose to introduce to implement that approach. Included as an appendix to the consultation document is the DfE’s proposed appendices to the subject content which contains of a list of notation for A level Mathematics and Further Mathematics and a list of formulae which must not be given in examinations. Responses should be submitted by 11th January

The mathematics in art...or the art
in mathematics?
“Mathematics, rightly viewed,
possesses not only truth, but supreme
beauty.” (Bertrand Russell, Mysticism
and Logic, 1919)
In this issue we explore the maths in art
and the art in maths.
Joseph Malkevitch of York College (City
University of New York) wrote for the
American Mathematical Society in
April 2015, entitled ‘Mathematics and
Art’. Melkevitch writes: “There are, in
fact, many arts (music, dance, painting,
architecture, sculpture, etc.) and there
is a surprisingly rich association
between mathematics and each of the
arts.”
It appears that rather than being two
separate disciplines, art and maths are
very much bound up together. As this
New York Times article Putting Art in
Steam explains, “being able to quickly
sketch to
communicate an idea
is an enormously
useful tool,” says
James Michael
Leake, director
of engineering
graphics at the
University of Illinois.
“To do engineering
you’ve got to be able
to visualize.”
There have been many recent
collaborations between artists and
mathematicians, and for several
reasons. Sophia Chen’s article: Get lost
in the internet’s mind-bending math-
inspired art (June 2015, Wired)
considers whether it’s the order in
mathematics that appeals to artists, or
“simply because math describes nature,
and nature is beautiful”. Chen looks at
five mathematically-inspired artists and
organisations that use both new
technologies such as 3-D printing and
traditional media such as textiles.
The mathematical artwork of Robert
Bosch is interesting, in particular TSP
Art and Simple Closed Curves,
illustrating Jordan's Jordan Curve
Theorem. “ Bosch can draw the Mona
Lisa with a single line. First he lays
down some dots on a grayscale version
of the image, and then he uses an
algorithm to connect the dots in a way
looks like the original.”

Maths-Art Seminars at London
Knowledge Lab was a monthly series of
maths-art seminars held in central
London. The idea for these seminars
grew out of the London Knowledge
Lab’s work in hosting the annual
international Bridges
Conference in London in August
2006. Regretfully, the seminars are no
longer organised, but the site remains
online as an archive.
The University of Oxford’s Art and
Oxford Mathematics web page
outlines the connection between
mathematics and art at its Mathematical
Institute. Included is a podcast of
Marcus du Sautoy's talk on the
connection between mathematics and
art. The Mathematical Institute has a
large collection of
historical mathematical models,
designed and built over a hundred
years ago. “The aesthetic beauty of the
models should be enjoyable for anyone
with an interest in mathematics, art or
history, regardless of your level of
mathematical training.”
Dr Ron Knott, Visiting Fellow in the
Department of Mathematics at the
University of Surrey, has created a web
page Fibonacci Numbers and The
Golden Section in Art, Architecture
and Music, which has a wealth of
information, examples and links about
the Golden Section, including
Miscellaneous, Amusing and Odd
places to find Phi and the Fibonacci
Numbers.
The Virtual Maths Museum presents
artists who use mathematical ideas as
subject matter and/or inspiration: “In
recent years, the advent of computers
has made possible the development of
various forms of digital art that allow
artists and mathematicians to cooperate
in a highly synergistic fashion.”
For examples of
innovative and creative
work by mathematics
practitioners and artists
who are crossing
mathematics-arts
boundaries, there is an
array to be seen on the Mathematical
Art Galleries website, the online
home of the mathematical art exhibits
from the annual Bridges Conference
and Joint Mathematics Meetings. The
exhibition comprises 2D and 3D
mathematical art, ranging from
computer graphics to quilts to
geometrical sculptures. The
Mathematical Art Exhibits page links
to photos of artwork from upcoming and
past conferences.
MoSAIC is a collaborative effort
sponsored and funded by MSRI
(Mathematical Sciences Research
Institute) and administered by
the Bridges organisation. Together,
they are creating a series of
interdisciplinary mini conferences
and festivals on mathematical
connections in science, art, industry,
and culture, to be held in colleges and
universities around the United States
and abroad.
The Golden Ratio The February 2013 edition of Monthly Maths looked at the Golden Ratio in Nature, Art and Architecture, and activities include finding Phi by experimentation and calculation. To access the ‘Beauty is in the Eye of the Beholder’ PowerPoint teaching resource that accompanied this issue, visit the M4 Magazine web page, scroll down to Archived Monthly Maths at the bottom of the page and look for February 2013 in the menu.

Beauty in Mathematics
according to their comprehension of the
equation, from 0 (no comprehension
whatsoever) to 3 (profound
understanding). The distribution of post-
scan ratings showed that there was a
highly significant positive correlation
between understanding and scan-time
beauty ratings.
The mathematical subjects were asked
four questions about emotional
responses to equations. All answered
affirmatively to the question: “Do you
derive pleasure, happiness or
satisfaction from a beautiful equation?”
By contrast, out of 12 non-mathematical
subjects (with experience of
mathematics up to GCSE level), the
majority (9) gave a negative response
to the same question. The researchers
supposed that non-mathematical
subjects who had rated any equations
as ‘Beautiful’ “did so on the basis of the
formal qualities of the equations—the
forms displayed, their symmetrical
distribution, etc”.
The formula most consistently rated as
beautiful (avg. rating of 0.8667), both
before and during the scans, was
Leonhard Euler's identity:
Most consistently rated as ugly (avg.
rating of −0.7333) was Srinivasa
Ramanujan's infinite series for 1/π:
Study author Semir Zeki writes,
“Relegating beauty to the study of art
and leaving it out of science is no
longer tenable.”
The experience of mathematical
beauty and its neural correlates is a
2014 original research article by Semir
Zeki, John Paul Romaya, Dionigi M. T.
Benincasa and Michael F. Atiyah, who
suggest that: “Art and mathematics are,
to most, at polar opposites; the former
has a more “sensible” source and is
accessible to many while the latter has
a high cognitive, intellectual, source and
is accessible to few. Yet both can
provoke the aesthetic emotion and
arouse an experience of beauty,
although neither all great art nor all
great mathematical formulations do so.”
Fifteen mathematicians were asked to
view a series of 60 mathematical
equations and rate each one on a scale
of −5 (ugliest) to +5 (most beautiful).
Then they scanned the subjects' brains
with functional MRI as they looked at
the equations again. The pre-scan
beauty ratings were used to assemble
the equations into three groups, one
containing 20 low-rated, another 20
medium-rated, and a third 20 high-rated
equations, individually for each subject.
These three allocations were used to
organise the sequence of equations
viewed during each of the four scanning
sessions so that each session
contained 5 low-rated, 5 medium-rated,
and 5 high-rated equations.
Each subject then re-rated the
equations during the scan as Ugly,
Neutral, or Beautiful. The frequency
distribution of pre-scan beauty ratings
for all 15 subjects was positively
skewed, indicating that more equations
were rated beautiful than ugly. After
scanning, subjects rated each equation

The Virtual Math
Museum has a
gallery of samples
mathematical art,
including that by
Robert Bosch (see
page 1):
“Mathematics and the
graphic arts have had
important
relationships and
interactions from the
earliest of times, for
example through a
common interest in
concepts such as
symmetry and
perspective that play
an important role in
both areas. In recent
years, the advent of
computers has made
possible the
development of
various forms of
digital art that allow
artists and
mathematicians to
cooperate in a highly
synergistic fashion.
Our goal in this

National curriculum links: the activities
based on geometric Islamic patterns in
this booklet support learning about
shapes, space and measures. Students
at Key Stage 3 can study
transformational and symmetrical
patterns to produce tessellations.
The maths2art website promotes the
teaching of mathematics in ways that
are visually stimulating, for pupils of a
wide range of abilities in Key Stages 3,
4 and 5. “Using a project to teach
maths can be more meaningful for
pupils than teaching the curriculum
areas of shape and space, number and
algebra in distinct units of work. It can
allow them to explore their own ideas at
a pace which suits them whilst making
meaningful connections between
different areas of maths.” Projects
include:

The M4 Editor found plenty of arches on a
recent trip to the USA. See the MEI Facebook page.
There’s something very pleasing about the shape of an arch. Classically an arch ought to be a semicircle, but over the centuries arches have evolved, especially in churches and cathedrals, into an amazing array of shapes.
Take St Paul’s
Cathedral in
London. Designed
by the unbeatable
engineering team
of Robert Hooke
and Christopher
Wren. From the
inside and the
outside you see
hemispherical
domes and if you
didn’t know it then
you’d never guess
the cleverness of
the construction
within.
Hooke had worked
out that a hanging
chain and a
perfect arch have
the same shape:
“as hangs the
flexible line, so but
inverted will stand
the rigid arch”. It
was this key
understanding that
powered the
design of Wren’s
amazing buildings.
Hooke thought
that the shape of
the perfect dome was the cubico-
parabolical conoid, i.e. the cubic y = ax3
rotated about the y axis. He was very
close!
The Wren Library in Trinity College
Cambridge has arches, but where are
they?
Amazingly, Wren hid them away in the
foundations – but upside down! He
recognized that the muddy reclaimed
land by the river Cam was too weak to
take the
weight of his
proposed
building so
he created a
raft made up
of inverted
arches.

mathematical progression. And if you
wondered what the pointy pinnacles outside
on the top of the roof are for – no, not just for
decoration – they are the weights necessary
to hold the uppermost stones in place against
the huge sideways forces generated by the
vaulting. It’s like putting your foot against a
ladder to stop it from sliding. They’re
decorated to make them look pretty.
Am I allowed another Cambridge arch?
It is the so-called
Mathematical Bridge
in Queens’ College.
So many stories are
told about the bridge
– they’re all wrong!
What is true is that the main lower arch is
made up of seven straight lines. Yet it looks
like a smooth curve. I think that’s what
Newton had in mind when he invented the
calculus (or was it
Leibnitz?!) that if you
break a curve down into
little bits of straight lines
then it becomes very
simple. This bridge is what mathematicians
call an ‘envelope’ – straight lines making a
curve. So simple, so beautiful.
My jaw just dropped
when I first saw the
Millennium Bridge across
the Thames. I imagine
Wren and Hooke are
looking down from their
lofty dome. They see
the cables of the bridge.
“I told you so” Hooke
mutters. “Ut pendet continuum flexile, sic
stabit contiguum rigidum inversum, as hangs
the flexible line, so but inverted will stand the
rigid arch”.
The bookcases inside the building
bear down directly on the pillars of
the arches as you can see in the
diagram opposite. It’s funny that
all this engineering beauty is
hidden away. I suppose nothing
has changed. The amazing
engineering under the bonnets of
our cars or in our mobile phones is
totally hidden from view. Just
imagine how much more
interesting airports would be if
there were windows into the
baggage handling area, or if there
were working models of turbofan
engines!
Perhaps the highest evolved form
of the arch is in the fan vaulting at
King’s College Chapel, again in
Cambridge (sorry for all these
Cambridge references – but I ride
my bike past these amazing
buildings twice a day and never
cease to marvel at them).
From the outside the King’s Chapel
looks kind-of square and maybe a
bit dull. But those big exterior
pillars are part of the engine room
of the fan vaulting inside. The thin
spidery stone filaments inside (see
photograph, left) are like lines on a
graph, illustrating the lines of
thrust. The forces are channelled
into the pillars in an orderly

The MEI Maths
Item of the
Month is a
monthly problem
aimed at teachers
and students of
GCSE/A level
Mathematics.
Each month a
mathematical problem is added to the
home page of the MEI website. The
MEI staff are all mathematics
enthusiasts and putting an interesting
problem on the front of the site is a
technological way of wearing our
mathematical hearts on our sleeves.
The first Maths Item of the Month
appeared in September 2006 and there
have been over 100 items since then.
A full archive of the problems is
available on the site and they can be
used for enrichment, problem solving or
as a way to encourage mathematical
thinking/proof.
A curriculum mapping for the problems
has recently been completed and this
can be seen at: mei.org.uk/miotm. This
is mapping is not intended to be
comprehensive – for example many of
the algebra or geometry problems can
be used with GCSE or A level students.
There are also a number of problems
that were hard to categorise and form a
fairly lengthy set of miscellaneous
problems at the end!
One of my favourites is one of the
earliest ones from December 2006:
“19 not out” – Some positive numbers
add up to 19. What is the maximum
product?
There is also usually a Christmas-
themed problem for December.
December 2014’s was:
“A Christmas Star” – An
eight pointed Christmas
star is made with a gold
layer and a silver layer.
What fraction of the gold layer is
covered by the silver layer?
Another resource
that has had a
significant impact on
me is Improving
Learning in
Mathematics (often
known as the
Standards Unit box).
The full set of materials in available, for
free, in the National STEM Centre e-
library.
The materials form a definitive guide for
using active learning approaches with A
level or GCSE students. There is a
range of activities including open
questioning, card sorts, group work,
learners creating their own questions
and many others. All of these are
presented in the context of lesson plans
so that teachers can see how to use
these strategies effectively to improve
students’ understanding.
There is also a set of professional
development materials that can be used
by a Mathematics department to
develop teachers’ skills across a
number of areas: learning from
mistakes and misconceptions, looking
at learning activities, managing
discussion, developing questioning and
using formative assessment.
Maths, Religion and ArtIt sometimes surprises people that there exist strong links between Mathematics, Religion and Art.Look at the images on the next few slides and describe the Mathematics you see.
Maths and ArtUsing some of these designs as inspiration, during this activity you will construct some of your own.
The ones here are nowhere near as complex or beautiful as the ones shown, but can be used as a basis for something more intricate.
Maths and ArtYou will need a pair of compasses, a ruler and a pencil (or a Dynamic Geometry Package) and will need to be able to:• Draw a circle and divide it equally into six• Bisect a line (perpendicular bisector)• Bisect an angleThese skills are outlined on the next slides.
Divide a Circle Equally into Six
• Mark a point on the circumference
• Place the point of the compass on the mark and make a mark on the circumference
• Repeat until you have 6 marks
• Draw a circle and keep the compasses at the same radius throughout
Perpendicular Bisector• Open a pair of compasses to approximately
¾ of the length of the line • Place the point at one end of the line and
draw arcs above and below the line• Keep the compasses at the
same radius, place the point at the other end of the line and draw arcs above and below the line to cut the previous arcs.
• Join the 2 intersection points
Bisect an Angle• Open the compasses • Place the point at the vertex of the angle and
draw an arc to create points A and B• Put the point of the compasses
on A and draw an arc• Keep the same radius, put the
point of the compasses on B and draw an arc
• Draw a line from the vertex of the angle through the intersection of the arcs

Teacher notes: Maths and ArtThis edition looks at Maths and Art and encourages students to use precise geometric constructions to copy the given designs and/ or create their own.
Students can use pencil, straight edge (measuring is traditionally discouraged) and compasses to construct the designs or could use a Dynamic Geometry Software package.
With each of the designs, working out how it has been constructed and the geometric properties involved is the first step and may require quite a lot of discussion. Working individually with pencil and paper methods, but seated in small groups will encourage this. If using a DGS package, working with a partner should be encouraged.
For KS3 and KS4 students, use of pencil, straight edge and compass will reinforce some of the geometric constructions they should be familiar with, but A level students might enjoy these activities too.
Teacher notes: Maths and ArtOne way of extending the activity to make it more challenging, particularly for A level students, would be to ask them to use a graph plotting package to create some of the designs, which would require a good working knowledge of: equation of a circle, equations of straight lines and trigonometry.
Students may find it helpful to firstly create the design using pencil and paper methods or a DGS package. This will ensure they understand how it has been constructed before trying to create it using a graphing package.
Teacher notes: symbols
An opportunity for students to discuss something in pairs and then feed back to the class.
Teacher notes: Maths and ArtSlides 2 – 8When looking at the images, initially simply ask what students see, then probe their thinking by asking them to describe specific shapes, symmetry, and underlying structure.
Some designs are based on dividing a circle into 6 (and then 12 and then sometimes 24), whereas others are based on dividing a circle into 4 (and then 8 and then 16).
Often there is rotational symmetry.Sometimes there is reflectional symmetry in the structure, but one needs to look carefully at the colouring.
Ask students how they think the basic designs have been constructed. What mathematical or geometrical skills did the artist need?
Teacher notes: Maths and ArtSlides 9-13These slides ensure that students have the geometric skills needed to construct the designs.
Traditionally, a Geometer is only permitted a straight edge, pencil and pair of compasses to construct designs.
Teachers may wish to allow students to measure distances or angles, particularly if the students need practice at using a protractor or find using compasses difficult. Students will need to calculate the angle required in each case.
Teacher notes: Maths and ArtSlides 14-21These slides show 4 different designs for students to re-create.
Show students a design and ask how it has been created. They should then try to construct it for themselves.
If they cannot work out how to construct it there is a second slide for each which shows the construction lines. The teacher notes below describe the constructions in more detail.
Once students have constructed the design, they might like to make a more intricate version of it.
The 4 designs do not have to be completed in order, nor do students need to complete all of them. Slides 14, 16, 18 and 20 could be reproduced full size and groups permitted to choose which one(s) they work on.
Teacher notes: Maths and ArtChallenge 1: A Rangoli style pattern
• Draw a circle and divide into 6 equal sections
• Bisect one of the angles• Use this distance around the
circumference to divide the circle into 12
• Draw other circles using the centre point, these can be equally spaced, or not
• Use intersection points and lines to create a design in one section
• Reflect and repeat the design around the circle
Teacher notes: Maths and ArtChallenge 2: An Islamic style floor pattern• Draw a circle and divide into 16 equal sections. • Draw a diameter and then construct a
perpendicular bisector to obtain 4• Bisect one of the angles to obtain 8 and then
bisect again to obtain 16• Use this distance around the circumference to
divide the circle into 16
• Draw other circles using the centre point
• Use intersection points and lines to create a design in one section
• Reflect and repeat the design around the circle
Teacher notes: Maths and ArtChallenge 3: A Trefoil
• Draw a circle and divide into 6• Select 3 alternate points• Join each to the centre • Bisect the radius to obtain a
required centre point
• Draw the red circle to obtain the other centres• Draw the 3 circles
Teacher notes: Maths and ArtChallenge 4: Seven Circles (one solution)• The challenge with this construction is that
a radius needs to be divided into 3 equal sections.• The easiest way to achieve this – without measuring with a ruler – is
to draw a line, use compasses to mark off a short length, keep the radius the same, move to the new point , mark again and repeat.
• Using the red dots as the centre and radius, draw a circle
• Divide the circle into 6 sections• Draw concentric circles at the other marks• Use the intersection points shown as centres
for the other circles with the radius the same as the central circle
