Representtion of basic isometries through square ornaments
Roubíček, Filip
The poster deals with basic isometries: point reflection, rotation and translation as composition of two line reflections. It presents some activities that support observation and intuitive cognition of isometries. Square ornaments were designed by composing mosaics, cutting folder paper, drawing, printing.

Geometrical imagination as a part of mathematical literacy
Roubíček, Filip
The paper deals with geometrical imagination as ability to interpret geometrical content, evoke images and manipulate with them. It describes approaches to teaching of geometry at primary school (natural geometry, principles of didactical structure of geometry) and activities for development geometrical imagination of pupils.

Přirozená diferenciace v matematice
Dolk, M. ; Hošpesová, A. ; Krauthausen, G. ; Roubíček, Filip ; Scherer, P. ; Selle, A. ; Swoboda, E. ; Tichá, Marie
Coping with heterogeneity and motivation of all students independent from their capabilities, is one of the great challenges in primary school, especially for teaching and learning mathematics. In the project NaDiMa several substantial learning environments enabling "natural differentiation" were designed, tested in the classroom and will be analysed.

Representational envinonments for plane transformations
Roubíček, Filip
The paper includes some illustrations of representational environments suitable for teaching of plane transformations in lower secondary school, namely reflection, rotation, and translation. It deals with properties of transformations, composition of reflections, and in particular various forms of modelling: reflecting, pinking, tracing, printing, and patterning.
