摘要：The paper focuses on the investigation of relations among perception of fraction as a measure and addition, equivalence, comparison of fractions. Arising from the previous studies, two research questions were stated. The first deals with the connection between location of the fraction on the number line and comparison and equivalence of fractions. The second deals with the connection between location of the fraction on the number line and addition of fractions. As a research tool, one part of the special developed fraction test connected to Sfard’s theory of reification was used. For data analysing Statistical Implicative Analysis was used. Sample consisted of 930 learners at the age of 15 in Slovakia.
