Geometry & landscapes

-

Hello everybody! Here we have a new entry, which is the last one of my trilogy under the name "Geometry & .... ". After talking about Geometry & art, but also about Geometry & music, today we are going to describe the impact that geometry has in the landscapes around us.

As teachers, we should encourage our students to understand the reality through this geometrical perspective. Something really close to them, as it is the city, should be used as a potential resource.

Maths are around us. Angles, polyhedrons and so on are elements that we can build up in our minds. Taking a look on the different walking paths, the streets and the buildings, the pupils will be able to rediscover their city from a new perspective, the GEOMETRICAL ONE. 

In this entry, I just want to show you an evolution on the cities' construction along the history, a really interesting content that can be applied at schools to teach both social sience and history, but also mathematics.

1) The most ancient city that has ever been found is Al Rawda (Siria), from the 2600 b.C. Nowadays it is still being dug because it was totally covered by the sand. The picture shows us a representation on how the city is supossed to be and, of course, we can appreciate the impact of geometry in the distribution of it.

This tupe of city has been repeated in Mesopotamia along many years. Examples are Hamadan and Firuzabad.


2) Talking about Greece and Rome, they really reinventated a way of distributing the cities. To the greeks, whose main important urban-planner was Hipodamos de Mileto, the grid was the perfect way of creating the cities. In rome, it was also used this plane, but they combined it with a circle shape.


3) Going through the time, we can arrive to the medieval period. As they were always in war, the distribution changed. The people lived behind the walls, being a totally disaster the organization of the city. It was a type of labyrinth where there was no geometrical order. Toledo was a great example.





4) Finally, and not spending too much time in all the eras, we have to talk about the current times. Everything changed, and everything will still be changing. However, we have cities such as Barcelona, in our country, or also examples as Paris.

TO CONCLUDE, I encourage you to explain your students’ geometry, the geometrical proportions and the use of geometry in our daily life using the cities as a clear example. To do so, apart from investigating, I totally recommend you to use GoogleEarth.

 
Searching on the internet, there are many illustrative videos on how to create your own city through geometry. Apply it with all your students! https://www.youtube.com/watch?v=vafperyUBWg

Road Safety

As we have been seing in the different entries, geometry is a theme that can be worked properly in a transdisciplinary way with all our students. In this new entry, and as a new suggestion on how to work, I invite you to think off Geometry and the relation with the ROAD SAFETY. We can work in an inductive way, cause this theme allow us to transmit the information to the students working with the  VISUAL THINKING , an strategy I totally recommend you to use with your students, who will be totally able to interiorize it. ACTIVITY PROPOSAL: As I have stated before, try to make students think. Show them this picture and ask them where are there geometrical figures, and what they think each piece represents.  Which polygons can you see on the picture? After doing that, we can provide them with tools such as this chart that will make them establish relations between the geometrical figures and their meaning in road safety. To conclude, I also invite y...

Fashion victims of geometry

Today we are going to talk in this new entry about the different designs in fashion which are compound by geometrical shapes. In ancient civilizations maths, religion and arts weren't divided. Nowadays, the geometry is supposed to be a reference for the new designers. As we should know, students are very influenced by fashion and the new trends. We are able to use those elements to make them see the geometry as something useful and dinamic, guaranteeing  Fashion is fascinated on using geometry, because those patterns allow to create incredible dresses, T-shirts and pieces of arts. It is not necessary to create complex geometrical designs. If you look at this photo, we can do beautiful things we some simple elements. The geometrical patterns used in the fashion designs, squares blacks and white, circles, hexagonal shapes, or line segments are really important in the collections of the new designers.  So.. Why don't we apply this fashion to our students? ...

Geometry & Art

In the last entry we talked about geometry & music. Did you find it interesting? I hope so! The following entry will show another vision of the geometry. As I told you on the introduction, I pretend to provide you with different resources and tools to work the geometry with the students in a motivating way and making it real to them, so they will be totally engaged. Can you imagine with is the area we are going to work on today?... Geometry seen from the Artistic Expression.  From the past to our current times, mathematics and arts have been really related. The simmetry, proportions and the geometry are concepts specially important in arts. If we observe a sculpture, a draw or the architecture we can see that the artists have a mathematic view.    🔺  Do not forget that most of the important mathematicians were artists, and viceversa.  I am offering you a new possibility. Appart from studying geometry in a transdisciplinary way next to music...
