Geometry is an extensive field with many
applications in real life. To introduce this topic we think that it could be a
good idea to make a small project with the students. We can ask them to take pictures of geometrics figures or patterns in
the façades of the buildings. Then, they can describe the elements with the
knowledge they already have. I have done my own quest, and here are the results:
Illustration
1. Pasaje Cuartel de Caballería
What can we say about this first composition? First of
all, it is plane figure. Then it is formed by three parallel squares. Each square has
4 semi circles, opposite to each other, creating like a kind of flowers. If we
duplicate again and again this composition, we would have a tessellation
because (1) all squares form a tessellation because there are not any gaps and
(2) there are not geometric figures overlapped.
Illustration 2. Tara building, S/ Tara (Dublin). Autor: Esteban Zamora.
This
composition could have been a mosaic.
It is made of diagonal strips that converge, then, the artist created rhombus painted in different colours. I say it could have been a mosaic
because mainly the figures created are rhombus, but then intentionally, the artist has broken the symmetry in
the frames of the two sides of the front building.

3. Building in Av/ Moliere (Málaga) [Self-made].
This seems harmonious work seems to be the small
windows of the bathrooms or the corridors of the building. It can perfectly
create a mosaic, made of a equilateral triangle that is cut in three small
triangles… it is simple but effective and it is amazing how we can create
beautiful compositions with just one single geometric figure.
Illustration
4. Detail of a house (Dublin) [Self-made].
In the front of the building of this house, we can see
different geometric elements. In the doors there are semi-circles, rectangles
and figures that aren’t exactly rectangles or semi-circles, but figures that
have those elements. There is also, in the traffic sign, a circle, etc.
Illustration 5. Detail
of one of the many churches in Dublin. Autor:
Esteban Zamora.
This an arch of the many types of arches that exist in
the history of the architecture. This case is a pointed arch, typical from baroque architecture among others.
With small project we want our students to appreciate
the implications that geometry have in our lives and analyse their features. It
can be done, for example, through jigsaw¸ a technique of cooperative
learning. With this technique, groups of students investigate about a topic,
becoming experts on it. Then, the different groups of pieces of the puzzle,
divide themselves and go around the other groups explaining what they have
learnt, so that everybody learn about every topic, but you are only an expert
on one of the topics.
Maybe from now on, they would be observing the world
with other glasses, analysing with more knowledge the reality, or we would be
creating future architects or art historians… Stay tuned for next posts!
