This document outlines a geometric design workshop that uses geoboards and the software GIMP to explore geometry. The workshop consists of 4 sessions: 1) Drawing shapes on paper and online geoboards, 2) Drawing 3D shapes on an isometric geoboard, 3) Using GIMP grids and templates to draw plane and solid figures, and 4) Inventing and coloring original geometric designs.
Geoboard workshop
- 1. from the geo board to the geometric design
- 2. WORKSHOP: FROM THE GEOBOARD TO THE GEOMETRIC DESIGN Geoboards were invented and popularized by Egyptian mathematician Caleb Gattegno in the 1950s.It is useful for studying geometry, symmetry and transformations. A geoboard consists of a board where some nails have been partly hammered into a piece of wood in a particular pattern. Figures are made on the geoboard by stretching rubber bands from one nail to another until the desired shape is formed. 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 to use GIMP and its possibilities using greed’s to draw figures and geometric designs. First session The geoboard. Drawing figures on a squared geoboard and on an isometric geoboard on line.
- 3. Second session. Drawing volume figures on an isometric geoboard on line Gimp: Using templates and grids. How to draw lines.
- 5. Third session Gimp : how to draw and colour plane figures and volume figures. Draw symmetrical figures
- 8. Fourth session Invent, draw and colour all kind of figures.
