CANARIAN CULTURAL HERITAGE

 

CANARIAN PINTADERAS

Discovering Pintaderas Canarias: Ancient Canary Island Stamps and a Creative Geometry 




ACTIVITY

 Read the text in this image carefully, look for errors, and point them out:

Examples of Pintaderas 

Below are some representative examples of pintaderas canarias

These images show the variety of shapes and motifs commonly found in archaeological collections.

PINTADERA MAGEC OR SOLAR



PINTADERAS WITH ASTRAL SHAPES





Look for patterns such as triangles, squares, spirals, or combinations of regular polygons arranged in circular compositions. These will be helpful for your activity.

Important: First Create the Design on A4 Drawing Paper

Before progressing to any hands-on activity, students must first create their pintadera design on A4 drawing paper.

This step allows you to:

  • Plan the proportions of the geometric pattern

  • Decide which polygons to use

  • Experiment with symmetry and composition

  • Prepare a clean reference drawing (the sketch in your note book)

This A4 design becomes the blueprint for the optional extension activity.


5. Optional Extension Activity: Create a Pintadera Using Modeling Clay

For students who want to take the project further, there is an optional creative activity:

Make Your Pintadera with Modeling Clay

Students may:

  1. Shape a circular clay tablet.

  2. Transfer the geometric design from their A4 drawing.

  3. Carve, press, or sculpt the lines and shapes.

  4. Add textures or raised surfaces inspired by archaeological pintaderas.

This activity allows you to connect more deeply with the original purpose of pintaderas, exploring how ancient artisans might have worked with similar materials.


Learning Goals

  • Understand the cultural significance of pintaderas canarias.

  • Identify and analyze geometric patterns in historical art.

  • Use mathematical concepts to create an original artistic design.

  • Connect cultural heritage with creative expression.

PROJECT: CD MANDALAS MOBILE


PROJECT:  CD MANDALA MOBILE




Let´s pratice the Geometrical Constructions by designing our own MANDALA and paint it in a CD.








NOW LET'S GET STARTED WITH THE CD

YOU WILL NEED...

                1. CDs to recycle
                1. YOUR MANDALA
                1. A paintbrush
                1. Relief paint or permanent markers
                1. Glass or acrylic paint
                1. Enthusiasm and creativity

STEP BY STEP

PEEL THE CD

There are several methods: either in boiling water or cut a piece of adhesive tape, stick it firmly onto the CD, and pull sharply. Using a cutter, carefully make a radial cut on the side of the CD with the aluminium. Do this very gently, taking care not to damage the plastic as much as possible. 



COPY YOUR MANDALA TO THE CD 
AND ASSEMBLE THE MOBILE

UNIT 1: REGULAR POLYGONS 1

REGULAR POLYGONS

Our first Technical Drawing Activity will be a mandala done with regular polygons. Here are a few tutorials to refresh your knowledge about the Regular Polygons' constructions.






Regular Polygons 


Inscribed in a circle

We are going to draw polygons using two diferent methods: 'Inscribed in a circle' or 'given the side'.
