WORKSHOP: FROM THE GEOBOARD TO THE GEOMETRIC DESIGNGeoboards were invented and popularized by Egyptian mathematician CalebGattegno in the 1950s.It is useful for studying geometry, symmetry andtransformations.A geoboard consists of a board where some nails have been partly hammeredinto a piece of wood in a particular pattern. Figures are made on the geoboardby stretching rubber bands from one nail to another until the desired shape isformed. We will first work with a paper geoboard drawing different figures.After that we are going to work with geoboards on line. Finally we are going touse GIMP and its possibilities using greed’s to draw figures and geometricdesigns.First sessionThe geoboard. Drawing figures on a squared geoboard and on an isometricgeoboard on line.
Second session.Drawing volume figures on an isometric geoboard on lineGimp: Using templates and grids. How to draw lines.
Third session Gimp : how to draw and colour plane figures and volume figures.Draw symmetrical figures
Fourth session Invent, draw and colour all kind of figures.
