Topic:
Geometry
This is a collection of tasks about transformation, symmetry and tessellation. This presentation provides some reference materials: https://dl.dropboxusercontent.com/u/4210789/me/mini/tiling/index.html More workshop materials are developed in a summer course for secondary students on these topics: 1. transformation and symmetry http://tube.geogebra.org/student/b320095 2. tessellation http://tube.geogebra.org/student/b320097
