Adventures of one triangle

Biljana Stojičić, Zorica Marinković

Our goal was to join isometric transformations with real life and playful activities. Properties of shape pattern schemas are formative idea for representation of isometric transformations. We found very interesting to use a kaleidoscope in that purpose because of flat mirror properties. Using kaleidoscope and kaleidoscope made images students will be able to demonstrate an understanding of key concepts in that field of school mathematics and discuss it on different levels.
