## Face, Maths and Evolution. How does it all mix?

Would you believe me if I said that mathematics can judge your facial proportion? Well unfortunately it can in a very accurate and understandable way.  In our most recent input for our Discovering Mathematics module we unearthed how to draw a face accurately. For myself I have always had a creative ambition and enthusiasm, but I can say that I consciously – and even happily – avoided ever drawing an accurate face to gain my Higher Art and Design Qualification.  It wasn’t until this input that I have ever successfully accomplished my avoided dream.

##### Introducing ‘The Golden Ratio’

Initially we were instructed to draw a face on one side of an A3 piece of paper. As you can imagine this triggered a few negative responses along with ironically a small part of art anxiety rather than maths anxiety. Like myself you will begin to wonder how on earth drawing a face has any connection to maths. It wasn’t until we were indulged on the beauty of drawing an accurate facial proportion. Everyday countless people have looked in the mirror and ridiculed there physical appearance.  I would argue that at this moment in time there has never been a greater pressure worldwide to look, rather than be,  your best. However, without knowing it you are judging the mathematical proportions of your facial features rather than your face itself.

To break it down simply, the shape and size of your face can be segmented into different groups. This discovery can unfold the ground breaking realisation that the human face is like a jigsaw. There are many different parts which aline and fit together to construct each of our individual faces. This is make clear by what is know as the Golden Ratio.  This discovery by Dr. Stephen Marquardt identifies the proportions and measurements of each facial feature that would form the desirable face (Meisner, 2014)  . In most cases this discovery has influenced reconstruction in cosmetic surgeries of people world wide. This is exactly what we considered when redrawing our original face.  Ideally the stature of a perfectly sculpted face would include;

• The inner and outer corners of the eyes to be in line with the center of the nose
• The outer edge of each nostril to be in line with the inner corner of each eye
• The center line of the chin to a line with center of the upper lip
• The tops of the ears to be in line with the center line of the eyes
• The bottom of the ears to be in line with the bottom of the nose

As seen in the picture above, when considering these proportions and measurements it made it dramatically easier to redraw our original portrait. The contrast when considering and understanding proportions is undeniable. Understanding the relationship between features meant that shape, scale and proportion became much more understandable. Mathematics has made this possible through comparing measurements of facial features, without this an ever-growing cosmetic would not be able to function. By segmenting features together and build considerable knowledge of these proportions, the end result has greater accuracy. It achieves realistic dimensions of the human face.

##### The golden ratio vs. primates

Studying this topic immediately fueled my interests to link the facial proportions of The Golden Ratio to the facial structure of primates. Science has generously allowed us to explore the connections and evolution of humans themselves. Without delving to much into scientific theory, the theory of evolution devised by Charles Darwin concludes that all species have devolved from a small string of lifeforms (BBC, 2014). This is where the link between humans and primates can be made. Over time genetic differences have reshaped our species both physically and mentally. The theory of evolution has brought to life scientific evidence that humans are derived from primates. Using my new profound knowledge of facial proportion I thought this may provide and enciteful comparison.

Looking at the pictures above you can see how some proportions of The Golden Ratio can seen within the facial structure of these primates. Although there are some physical difference such are the ears, there is a clear connection between our faces and these primates. By showing that these primates do not have a the structure of The Golden Ratio this can in fact relate to the differences between physical appearance among humans. Our eyes don’t match. Our ears don’t match. Everything about our faces are different yet we all have small common forms of facial structure, just like primates. As explained by Burrow et al. (2014) humans and primates can be physically compared because of the way our muscles are positioned in our faces. It is this connection which makes it possible to see similarities between ourselves and primates using The Golden Ratio.

In terms of the bigger picture in depth exploring mathematical concepts within the primary school will open rather than close the mind of children. By weaving concepts together and making cross curricular links children will be able to access the world around them through a new lens. This will allow them to use imagination and fun within the world of maths rather than be tied to textbook procedural work. A key concept which drove the Profound Understanding of Fundamental Mathematics according to Ma (2010) is Basic Ideas. This allows teacher to craft they’re approach in a way the takes a component of maths (in this case proportion and measurement) and spark by guiding children through its exciting structure. Therefore, the maths curricula will not inhibit but expand children’s approaches and interests in the world we are a part of. Furthermore, this also signifies the importance of competence within teachers themselves. Unless and educators work individually, and together as a body, to acquire profound understanding of fundamental mathematics how can we expect pupils to feel the same? The level of understanding which educators are capable of mimic the level of understanding which their pupils can achieve (Bregner and Groth, 2006). Building on mathematical knowledge and relating it to other concepts throughout the education curriculum will only encourage children to achieve in maths rather than be limited by teachers’ deficiency’s. This attitude should be established both nationally and internationally in order to provide children with the opportunity achieve with flexible and stable knowledge and understanding.

## Can we touch the moon?

Education is one of the first places that allow children to build a realistic foundation of knowledge. It wasn’t until my first school placement that I began to understand the importance of putting fact into visual representation that all children understand. Therefore, if this is inaccurate it will result in a generation (or even generations) of flawed understanding. There is no better example of this than Space.

Without most teachers realising, there will be a time that a child in there class stares out of the window imagining what is beyond our drizzly, damp and occasionally blue sky. It is this unknown environment which beacons children to explore and build there experiences and knowledge of Space. I can happily say that I was most definitely one of those children. Primary 5 was the year of Space! Without a shadow of a doubt the experience that I had was incredible, I was well on my way to becoming a fully fledged astronaut. However, despite having amazing experiences, I cannot say that my knowledge of Space is at all realistic. Sadly this will be the case for many others who have or are in education at this time.

Until recently, I did not realise the enormity of Space. There is no word to describe how ginormous Space actually is and this is exactly where Space education must start. For me this is where my own knowledge is false because I was not aware of the scale of space.

To put this into perspective you can look at the distance between The Earth and The Moon. To the majority of people – including myself-  believed that the The Moon was only a short distance away when in reality it is actually much greater than that. To scale you can approximately shrink The Earth down to the size of a basket ball and The Moon down to the size of a tennis ball.  Using this scale this means that a basketball and The Earth along with a tennis ball and The Moon are at a ratio of 5, 280, 000: 1 (The Science Asylum, 2017).

Using this scale we can put the distance between The Earth and The Moon into a realistic visual perspective.  The distance between the core of The Earth and The Moon is 238, 855 miles, when scale down using the ratio of the basket and tennis ball this distance is only 7.2 meters. In terms of what this looks like to scale it would look the picture below.

Encouraging ourselves as Educators to understand scale is extremely important, not only to physically represent Space in our own mind but in the minds of the those within the classroom. As fun as it may sound, taking children to Space is not a class trip that can be offered within my lifetime. This is why it is so important to allow children to experience accurate scale. This can be linked to the ideas of a logarithmic scale present in the minds of those inadequate and unrealistic experiences. Bellos (2010) maintains that children believe that with unresolved understanding will be unable to fully interpret the realistic size of maximal numbers. From experience children believer that space looks simplistic; with planets knitted closely together on a perfectly circular orbit surrounding the sun.

Generic image of Space.

In reality it is believed that space actually looks like this!

This is only a small part of Space. Space is actual made up of millions of solar systems that most of which can be easily understood. In other words the universe is made us of billions of stars, these stars form galaxies and galaxies form the universe. Overall, in order to promote a Profound Understanding of Fundamental Mathematics educators must invite children to build knowledge into compound understanding. This can relate to Ma’s (2010) key concept of connectedness which focuses on connecting mathematical procedures to wider concepts, thus enabling a greater understanding. In terms of Space, knowing the size of an the environment highlights intellectual solidity (Frobisher, 2007). Only when this happens children will be able to be able to explore the immensity of Space purposefully.

## the maths and creativity sandwich.

Never would I have imagined that myself or anyone could sandwich together maths and creativity. Yet what a wonderful sandwich it is! Realistically, the majority of people would strongly argue against this opening statement, my self being one of them, however let me tell you that it is more than possible.

Like most sandwiches it all begins with the bread and in this case it begins with MATHS and Art. If you wanted to find these breads on a supermarket shelf you would instinctively look at opposite ends. However, this is not true because they could actually be found right next door to each other.  My own experience of maths and art at school was not in anyway this experience. I would have confidently argued during my time at school that art was the elegant French baguette – thick, crunchy and popular-  and on the other hand maths was the sourdough of all breads – bland, odd tasting and for the select few. Although reflecting on this now I think differently. This week in discovering maths we were exposed the creative aspects of this once bland subject.

This adventure was sparked by looking in detail at shapes. We discussed the names, number of side and angles of a variety of 2D shapes such as triangles, squares and hexagons.

You are now wondering how does this relate to maths? And it begins by introducing the idea of tessellation. ‘Tessellation (or tiling) is a repeating pattern of shapes that fit perfectly together without any overlaps or gaps.’ Brown (2018). Simple shapes such as triangle and squares can tesselate because their angles can make a full rotation. But how do you do make it personal?….

1. Take an original shape, such as a square, and cut segments out of it.
2. You then take your segments and add them back onto a different side of the square.
3. You can then repeatedly join this new shape together by repeating, rotating or mirroring it.
4. Repeat it all over the page, your final result should be a wonderful tessellated pattern.

When this is practiced you can make magnificent patterns and works of art.  Traditionally this commonly used within Islamic art and patterns.

(Please watch this short clip to see many different types of visual tessellations)

Watson, C (2015)

As I discussed this shows that maths can be used in an engaging and exciting way and this is what is extremely important when introducing maths into any classroom. I believe that when you begin a maths lesson you have only a few moments to make it interesting otherwise children will switch off. This what brings me back to the sandwich. Do NOT present maths as the sourdough bread! Within tessellation alone there are hundreds of opportunities for children to put there own creative stamp on their maths sandwich. They can experiment with fillings, experiment with topping, experiment with size and most importantly of all they will understand how the sandwich is made.

This reiterates the concepts of Profound Understanding of Fundamental Mathematics (PUFM). For myself, by investigating this topic of tessellation alone my view of PUFM has evolved because I can see it represented in Maths! The root of tessellation is shape. Children’s basic understanding of shape will be to name the shape they see.  However, if pupils have PUFM  they can understand that if you alter the shape it will still have the same area. In other words pupils will not only be able to name the types of bread, they will   understand how the bread is actually made.

However because of constraints children will not have time to explore this and there for be unable to sandwich maths with creativity. So how do educators step of our this narrow box. Haylock and Thangata (2007) argue that drill like teaching methods which are reused over decades betray creativity. Thus how maths is taught in the classroom can either uplift or damage creative the link between maths and creativity. Similarly Maths needs to be understood by the educator before it can be understood by pupils (Setati, 2011). As a future teacher I will continue to encourage creative thinking and tasks classroom maths topics. If this is done by all it can transform Maths from a bland sourdough into a baguette.

## Do you know what an angle really is?

Most recently I have began the studies of my elective module Discovering Maths at University. Although we are only breaking into the second week of this module, I have immediately found it abundantly clear that this module will serve more than just knowledge of the Primary School mathematics curriculum; it will indefinitely open my eyes to the cracks of this subject.

On our very first input the class was asked how well we believe we know mathematical topics. Quickly I began to think that, like all others in the room, we would at least have a National 5 qualification in mathematics, therefore our knowledge of maths would be quite solid. Yet, is it actually? This was quickly answered when my lecturer was discussing angles he asked ‘What is an angle? It is the measurement of a rotation.’

In this single moment I realised that my knowledge of angles was molded into a way that I could only answer textbook questions. In my thirteen years of schooling I had never once understood what an angle was. My head was filled with knowledge about seeing right angles in every stair, corner and cupboard at my home, knowing how to measure them with a protractor and being able to name the different types of angles at the drop of a hat. Looking back on my experiences at school now, I know that I do have valuable knowledge about angles but none of it made sense until that moment. This is because I understood what an angle is.

It is moments like this that every child must have within their learning. As a student teacher there is an expectation that we must equip children with the knowledge to meet curriculum requirements. In many lessons this is the case, however knowledge should never be put in front of understanding. We can teach children a million different facts about the world around us, but if they do not understand these facts how will they be of any value to them? As a future teacher I now find that it is crucial that this should be a part of all learning because it will equip children with the ability to see and make links within their learning. This matters seems controversial throughout schools across the world as many have differing opinions about what the purpose of mathematics is.

Understanding mathematics is key aspect of specialist knowledge of fundamental mathematics. My early understanding of this phrase so far is that it is understanding the thing itself and all of its properties. Enthusiasts of maths in education such as Liping Ma highlight that understanding of mathematics in crucial in making sure that students have the greatest success (2010). Therefore, if children can understand the roots of mathematical topics, not just what they look like, this will allow them to have a profound understanding needed to progress learning. Similarly Haylock et. all (2007) found that mathematics promotes profound learning that allows children to understand the world around them. Thus, mathematics in school should not just require children to solve problems; they must create links with how these issues relate to everyday life. Looking forward I am excited to find out how my experience in this module will allow my conception of understand in maths to flourish and develop.

## How has home helped me?

Looking back on my time at university so far, I have realised that my accomplishments have came from myself and my choices. After completing my first semester I now know that the decision to stay at home was right for me. Prior to beginning University I felt anxious at the prospect that a lot of my course mates lived on campus and I didn’t.  I began to question, had I made the wrong decision? Is this going to make me isolated?  For anyone who is conflicted about the decision of home life or university life, I would say that all of my negative thoughts did not become reality. Although there might be a journey in the middle this does not impact your studies harshly.

Reflecting on my time at university so far I have realised that being a commuter had such a large impact on me. Over the course of semester 1 I had to discipline and manage myself in a way that I could feel as though I was achieving and also make that I was enjoying University. Managing university, work and a social life is not easy, however making it your own experience is how I feel being a commuter works. In terms of my personal attributes I would argue that my ability to work independently and manage time has increased dramatically. It became clear quickly that high school and university are extremely different. In terms of self studies in university, the work is yours and not for anyone else. Being involved in a multi-disciplinary peer learning group- within the Working Together module-it became clear that not only relying on your group is important. Making sure that your group knows they can rely on you is even more fundamental. Personally, I was able to do this because I was at home.

Home allowed me to have my own time away from all of the work load t university, I even found that my drive to and from university became a time of peace. Crucially I noticed that my time at home made me motivated and driven to achieve my best, not only that but to enjoy the time that I have. As my confidence of living at home began to grow, I found that it became much easier for me to organise things with my friends. Although moving from home to University is different, the main thing I have realsied that they share something in common. TIME. Time is all it takes to get yourself on your feet and running with it.

## Hartsford Uniform Conflict

Last year at the beginning of the first school term it became nationwide news when Hartsford High School in Kent had refused to let pupils enter school grounds because of their ‘inappropriate’ uniform which did not follow the school code of conduct.

While the head teacher of Hartsford had received positive feedback from local parents commenting that the code had set ‘high standards’ for school to be a highlight in the local community a small group of parents were out radged. Due to the teenagers being sent home from school parents brought it to the attention of the media that this had a catastrophic effect on their child’s education. The main issues came from a number of people who had ‘skin tight clothes on’, ‘inappropriate’ shoe wear and those who came without their blazers on. Many complained that those caught up in the situation were being prevented from missing the utmost vital education which could damage their studies, especially for those sitting exams. Since becoming local new this has become a conflicting topic of discussion.

Who is in the right?

In my perspective this could be argued from two points of view.

Firstly it is known that the way we dress allows us to express our different personalities. For some people wearing different shoes, clothes, hairstyles and accessories this can be a structure, which adds to their confidence, while they are at school. If this is true then why would it be acceptable to take this away from these young adults? On the other hand one of the main concerns coming from this story is money. In some cases the children’s parents were told to buy new uniform that was more appropriate but just because these things can be easily sourced in shops does that mean that everyone can afford them? Reading about child poverty this week has opened my eyes to the fact that a large majority of families struggle to make ends meet, if so then I don’t think it would be right to dismiss the fact that pupils might not have appropriate uniform because this is what is affordable for their family.

However on the other side of the fence I feel that having a set uniform for everyone in schools provides equality among pupils and their peers. If this code was not implemented it would isolate those from less fortunate backgrounds. All of a sudden school would become a competition of who has the best and most expensive outfit rather than what the real concern is. LEARNING.

As an aspiring professional I believe that the consistent attitude of the Head teacher and his staff has been positive in ensuring that standards will be kept in the school. By maintaining these standards will provide an education to pupils on what to expect in their future careers as the majority of professions have a set standard of how they expect their colleagues to dress. I see it from the perspective that, if you see a nurse on ward wearing a tracksuit or a police officer wearing jeans and a t-shirt while arresting someone, how would you react? How would that be different than wearing the correct uniform to school?

Sometimes building the small pieces of the puzzle first will help create a better idea of the picture. In this case I believe that this was the schools intentions and in the long term it will be worthwhile.

## Resource Allocation Input

When we first arrived in the seminar we were told to disperse ourselves among the tables so that we would be equally divided into 5 groups. The task to complete in our groups was to create an item which students like us would be able to use on welcome week to help guide us throughout our first few weeks at university. As we all began to discuss the ideas of what we could make, our lecturer had passed out envelopes to each table which inside contained different materials. These materials were what we would eventually use in order to create our product. Looking around I had no idea why we would be doing this task in particular.

While we opened our envelopes we found a wide range of materials inside such as paperclips, sticky notes, coloured paper and pens. However looking around the room I found that each group had different amounts of resources most particularly one group who had 1 piece of paper, blue tack and a pen. When observing oneanothers envelopes we found it extremely strange that we hadn’t been given equal materials. All I could think at the time was “what is going on?”

As each group separately began to explain their ideas in front of the class I noticed that the first two groups had been given so much praise for their ‘astonishing’ and ‘absolutely brilliant’ ideas. This put pressure on our group because we had fewer materials than them and our student help box was being held together by some paper clips. As we began to present our design we received no praise. Not a ‘Well done that’s great’ or even an ‘I like the idea’. Derek did not seem impressed with our design at all. The feedback got worse until it came to the last group and finally it clicked what was going on when Derek made it obvious he wasn’t listen in and stood on his phone through the entire presentation.

This was a lesson on teaching attitudes and resource allocations throughout schools and it is a valuable one.

By praising some groups for their efforts and leaving others to ask what they had done wrong it highlighted what is probably happening in schools RIGHT NOW. As a whole class we agreed that by changing our attitudes towards different children is can diminish their confidence in the class. It showed that those who come from wealthier, nurtured and sheltered communities are much more likely to receive the praise for their progression than others. Those who have the support of their families can sometimes progress faster than others, for some children this can make the difference in there future careers and ambitions. As teachers we have the ability to create a class atmosphere were children understand; everyone can help each other to improve, we aren’t good at everything and no one should ever be put down by their social background.

Moving on to resource allocation I find it extremely important to highlight that every school has better or worse resources than each other but it is how we use those resources to enhance the same level of learning that matters. Just because you go to a school in a deprived area doesn’t mean that you should be treated any differently in what you can accomplish academically.  After completing our Resource Allocation seminar I found myself thinking about how when we as teachers take on a class we are working with children who have completely different cognitions.

## How global racism shocked me

What is Race?

When asked in our Values lecture “What is your understanding of Race, Ethnicity and Discrimination”? At a first glance I thought that I would know exactly what these terms meant but I found it extremely difficult to come up with a set answer. I had noted that Ethnicity represented an individual or group’s culture or tradition and Discrimination was linked to isolating someone based on their beliefs, skin, culture or faith. The main part which surprised me was my definition on Race… because I couldn’t think of one.

In my opinion modern day Racism is very much still alive if so more than ever. While most people may believe that their country or even they aren’t racist we may still have unconscious bias, which mean to uphold an immediate reaction or opinion about a topic, but you are afraid to express your comment out of fear it is ‘socially unacceptable’. Having learned about this I find that it is the harsh reality of how modern day people think.

Recently during one of my university lectures we were given countless examples of racism from the days of the Ku Klux Klan and Nazi Germany, when civil right was far from being part of society. However what I found out about modern day Racism shocked me. You see these radical groups aren’t just found in the history books they are growing in the hundreds around the world NOW.
An example that we saw was a white nationalists group in Charlottesville around two months ago. In this video clip there was an estimated 400 people demonstrating against a peaceful park protest for ‘Black Lives Matter’. During this demonstration you could hear the nationalists shouting “blood and soil!” and “White lives Matter!”-often related to Nazi fascist campaign slogans- to retaliate against the protest group. Another example was when the nationalists drove a car at 80mph through a packed street of protesters who AGAIN were campaigning for ‘Black Lives Matter’ an incident which sadly killed one person and injured many others.

I personally uphold the opinion that everybody is on a level playing field no matter if they are Black, White, Asian, Catholic, Muslim the list is endless. Reflecting on my original opinion of discrimination I would say that it is much more extreme than I believed. Could you imagine the uproar which would happen if all of a sudden white people were seen to be inferior to black people? Or if white people were being murdered while they innocently protested or walked home at night? If we could not imagine this to be a reality for some then how it is acceptable for others to be treated this way?

As an aspiring future professional I will strongly maintain these views. I feel that from the moment that any child enters a classroom they should be accepted not only by myself as teacher but by their peers. I hope that teachers and myself can work together to encourage a positive attitude towards different cultures and traditions rather than find it acceptable for people to have such discriminant attitudes. However everyone must play their part in this.
