Talk about patterns in the mathematics classroom
Roubíček, Filip
The poster deals with the talk in the mathematics classroom which is focused on looking for relationships in a pattern. The communication of students is observed in the environment of geometrical patterns in a triangle grid and their transformation into arithmetic patterns or algebraic functions. It shows how pupils/students reason about relationships in these patterns and among these patterns, how they describe and express their generalizations in words or symbols.

Observing how future primary school teachers reason about fractions
Samková, L. ; Tichá, Marie
The contribution focuses on the possibility to use an educational tool called Concept Cartoons in future primary school teachers' education, especially as an instrument for observing how future primary school teachers reason about fractions. The task which we adapted to the Concept Cartoons form belongs to primary school mathematics, i.e. it focuses on the concept of a fraction per se, in particular on the parts-and-whole decision and on comparison of two pre-partitioned models with diverse wholes. Using Concept Cartoons, we observe which statements about the issue our respondents consider as correct, and which kinds of reasoning they use in their justifications. We also mention other related concepts (percentages), and related tasks from entrance exams to lower-secondary selective schools.

About some misconceptions related to argumentation skills
Samková, L. ; Tichá, Marie
The contribution focuses on various ways of proving general statements (external convictions, various types of empirical arguments, deductive arguments). We observe in details argumentation skills of future primary school teachers, and mention often occurring misconceptions. We offer inquiry-based education as a possible way to development of argumentation skills.

Rediscovering of geometrical constructions
Roubíček, Filip
The paper deals with the application of principles of inquiry based mathematics education in seminars of didactics for future primary school teachers, specifically with the activity focused on construction of known geometrical figures in the environment of folding paper. Seven students´ construction procedures of a square are presented in the paper.

Developing open approach to mathematics in future primary school teachers
Samková, L. ; Tichá, Marie
In our contribution we focus on the possibility to develop open approach to mathematics in future primary school teachers during a university course on mathematics conducted in inquiry-based manner. We analyse data obtained in the beginning and in the end of the course with respect to two main aspects related to open approach to mathematics: searching for all solutions of a task, and acceptance of different forms of notation of a given solution. Data analysis revealed in the participants three different shifts towards open approach to mathematics, and showed that after the active participation in the course each of the participants improved at least in one of the monitored aspects, and that none of the participants got worse in any of the aspects.

Inquiry activities with geometrical contents into preservice teacher education
Roubíček, Filip
The paper deals with the issue of implementation of inquiry-based approach into seminars of didactics of mathematics for future primary school teachers. Inquiry -stimulating teaching situations based on specific geometrical environments were presented to students. Students engaged in the solving of undefined geometrical problems that enables application od inquiry procedures, such as posing of questions, designing of solving processes, making experiments, reasoning, verification, discussion of findings and others. Three illustrations of inquiry activities realised with students and their reflection of inquiry are presented in the paper.
