Sažetak
Since textbook tasks are used to a great extent in classrooms, it makes sense to ask what requirements the tasks involve. This paper aims to show the importance of mathematical activities as a tool for analyzing the textbook tasks. Mathematical tasks may require students to carry out activities such as representation, computation, interpretation and argumentation. The study involved identifying which of these activities are required in the geometry chapters of middle-grade mathematics textbooks in Croatia. The results show that the geometry tasks predominantly require activities of computation, while activities requiring argumentation are underrepresented. This finding reveals that the activities in the geometry tasks put emphasis on dealing with numbers and terms rather than mastering geometric concepts.
