In Pursuit of Mathematical Art

Leave a reply

In a recent input in Discovering Maths, we had a chance to create some mathematical art and my favourite of these was a curve of pursuit.

(MathsMasterOrg (2011))

This is created by choosing a regular shape, making a mark an equal distance from each corner and joining these dots to create a slightly smaller shape.  Then repeat…and repeat…and repeat…

The finished product is almost an optical illusion – the straight lines appear curved and it is hard to believe it is created purely by drawing straight lines.  I think this is a useful activity to try with a primary school class because it provides an opportunity to develop a specialist knowledge of fundamental mathematics.  A curve of pursuit can reinforce the basic idea (Ma, 2010) of the properties of shape by challenging the perception of what a square normally looks like as well as concepts like rotation.

The intersecting lines and the amount of patience required to draw this reminded me of an activity I did with the class I taught on my recent placement.

Zentangle is described as a relaxing way to create a piece of art by using simple lines within a shape to create ”tangles” and each ”tangle” is filled with a repeated pattern.  I had chosen to try this activity during a particularly hectic few days for the class for a bit of mindfulness and I also recognised an opportunity in the intricate patterns for the children to work on their fine-motor skills.

There are no rules in Zentangle – something I thought the children would be pleased to hear but they were very hesitant to start without being told exactly what to do.  We looked at some examples together and soon after, they all set off ready to get creative.  Haylock and Thangata (2007) made sense of this reaction for me in discussing how when mathematical concepts are involved, shape in this instance, children are normally concerned with giving the ”right” answer – thinking divergently.  However, without realising, I was asking them to think convergently in this activity which meant they needed to allow for more flexibility and openness to see what would happen, for want of a better phrase.  We all really enjoyed it in the end as an art lesson.

Throughout this module, I have become more aware of opportunities to exploit the fundamental concepts of mathematics and I wondered if I could combine these two activities to give more mathematical purpose to Zentangle.

Admittedly, I would increase the measurements next time to give myself more space and I probably spent far too long doing this

BUT

I do think this hybrid of Zentangle/curve of pursuit is a good way of exploring the properties of shape whilst also considering Curriculum for Excellence’s principles for curriculum design (Scottish Government, 2018).  It incorporates personalisation and choice by encouraging the children to choose which regular shape they would like to use to create a piece of art as well as the patterns they fill it with and coherence as it could be used as one of a series of lessons looking at mathematical patterns in artwork.

The Daily Mile-matics

Leave a reply

Throughout this module, we have often been asked to reflect on our own experiences of learning mathematics at school and my memories are almost exclusively textbooks in the classroom and being excited that you had filled all of the squared paper in your jotter.  Fast forward 15 years or so to ‘Miss Duncan’ teaching mathematics on placement, I tried to include a lot of stimulating concrete material to introduce concepts and always asked the children how we might use the mathematics outside of school but didn’t actually use the mathematics outside of the classroom with them.  In this blog, I want to look further into some of the benefits of planning outdoor mathematics lessons as well as the challenges and give an example of how I might incorporate fundamental principles of mathematics in future lessons.

A benefit of any outdoor learning session is that it allows for a slightly different relationship between teacher and learner away from the, sometimes stressful, classroom.  This is supported in Maynard and Waters’ (2007, p.260) discussion about outdoor learning which states ”while the teachers indicated that they were unsure whether or not they should change their pedagogical approach when working outside, several indicated that they felt more relaxed outdoors.”  In the outdoor lessons I took part in during my recent placement, I witnessed a lot more teamwork and peer support among children who would normally be at opposite ends of the classroom in their normal maths groups.  So, outdoor learning may provide more opportunity for children to build important transferable skills and even improve relationships with peers and teachers than the more constrained nature of the classroom.

Much like morning break and lunchtime, an outdoor lesson is a chance to get some fresh air and expel some energy before returning to the classroom with more focus. This is echoed in the reasoning for introducing ‘The Daily Mile’ which encourages teachers and children to walk, run or jog for around 15 minutes each day to improve health and wellbeing.

NB: not the last mention of The Daily Mile… stay tuned.

However, as a student teacher, I can certainly say that outdoor lessons were a bit daunting. Fear of the unknown, or something like that.  It seems I’m not alone as Dillon et al (2006, p.107) cited teachers’ lack of confidence and limited time and resources as barriers to outdoor learning in our schools today.  Understandable, right?  Well, the good news is that these fears are already being somewhat alleviated by more exposure to outdoor learning early in teacher education.  The General Teaching Council for Scotland’s (2012) updated standards for provisional registration now state that students must demonstrate that they can use a variety of teaching approaches and resources before qualifying as a teacher – outdoor learning, for example.

So, how can we incorporate more outdoor learning in mathematics?

Back to ‘The Daily Mile’.  The class are already outside for at least 15 mins – it would be a good start to firstly make the most of this time for the children to start to develop a profound understanding of fundamental mathematics (PUFM).  However, as Bilton (2010, p.4) states ”merely taking indoor equipment outside does not constitute quality provision.”  Not to worry – the best part is that the resources are already there waiting for us.

In our ”Maths & The Great Outdoors” input, we were able to estimate the height of a tree by measuring the same distance on the ground.  We modified the method somewhat by (gracefully) looking at the tree upside-down and creating the 45° angle by continuing on from where we could only just see the top of the tree to the grass.  For those of you who didn’t have the pleasure of seeing this first-hand, the start of this video shows how a question like ”how tall do you think that tree is?” leads to discussions and problem-solving opportunities using basic ideas such as the properties of the triangle and how concepts such as estimation and finding an average help us answer the question (inter-connectedness).  This is just one example of many new ideas I have for future lessons, thanks to my participation in this module.

In conclusion, it is clear that outdoor learning has benefits and I don’t think anyone really disagrees with that.  Instead, what holds us back is the fear of trying something new.  New = good!  We know that teachers and children benefit hugely from learning in a ‘new’ environment, even if that environment is the school grounds they walk across every day,  We have discovered so far in Discovering Maths and as cliché as it sounds, maths really is everywhere.  It is simply not enough to ask the children where they might use their new-found knowledge, we must support them in using it so that they truly understand what it is they are learning about and why it is so important.

”4 for £1!”, ”buy 2, get the 3rd free!” Think fast! Or slow…

As a part-time store assistant in a popular discount store providing ”top brands at bottom prices”, my colleagues and I spend a fair amount of time filling up baskets of items considered to be ”Star Buys” with bright, yellow stickers to attract the attention of shoppers as they walk through the door.  On the (rare) occasion I decide to do an extra shift on the tills, I’ve lost count of the amount of customers who have claimed they ”only came in for a couple of things” before asking me to look out a couple of bags and a small trailer to accommodate all their bought goods.  These customers are likely to have succumbed to the power of the sticker and bought some things impulsively contributing to the estimated £144,000 we each spend during our lifetime on these sorts of purchases. (The Independent, 2018)

Our shopping lists are often ignored once we get into a shop full of these types of promotional offers therefore my question is how does mathematics link to what we call ‘impulse buys’?

After an input in Discovering Maths, I believe that it is much to do with the theory of loss aversion and how clever marketing appeals to one of our two systems of thought.

Loss aversion
This term describes the human need to prioritise avoiding loss and the feelings that come along with losing something over gaining something supported by Kahneman and Tversky (1979) who state that ”losses loom larger than gains.”  In the context of promotional offers in my work, the potential loss in question is the potential of missing out on a good deal.  Products featured in the ”star buys” section are portrayed as the week’s best deals but are not necessarily new products and can be found in the main part of the shop.  By placing them in a section of the shop in which the products change on a weekly basis, venders are introducing a sense of urgency to customers as they appear to only be available for a limited time.  When researching this effect, I came across a theorist named Timothy Brock (1968) who found that scarcity increases value (or desirability, in this example) and I can understand why phrases like ”limited time only” are used so heavily in marketing.

Thinking fast and thinking slow – impulse buys

Kahneman (2011) believes that our behaviour is a direct result of co-operation – or lack of – between two different parts of our thinking process.  System 1 wants to give a quick, impulsive answer based on intuition at first glance whereas System 2 takes a little longer to consider what’s going on to make the best decision.  Ideally, System 1 would wait for System 2 to have a look before deciding on what action to take but in certain situations, System 1 is so over-powering that we act before System 2 has had enough time to convince it to have some self-control. (as pictured)

With this in mind, I put this into the context of ‘Star Buys’ again;

  • System 1 & 2 enter the shop (not a bad joke, I promise…)
  • System 2 has the shopping list and advises System 1 to walk past ‘Star Buys’ because there will be a wider range of products in the main section of the shop
  • System 1 is already distracted by the yellow stickers and throws a few (impulsive) items in the basket – ”I need this!” or ”What a bargain!”
  • System 2 might be able to regain control to consider what products are best value but the impulse buys are likely to remain firmly in the basket.

1-0 to System 1.

On a more considered trip round the shop, System 2 would be able to employ basic ideas of mathematics to work out what product was best value by comparing price per litre, for example.  A shopper would also need multiple perspectives if working with a budget – perhaps prioritising within a list so that there was enough money for the most important items.  It is quite clear that clever marketing is the ‘Achilles’ heel’ of most shoppers and it is not hard to see how shoppers can get carried away and end up out of pocket.  Of course, everyone likes a bit of retail therapy now and then but for the sake of our bank accounts, let’s hold off until System 2 has given the thumbs-up.
