The teaching and learning of fractions have been getting public attention since it is one of the most problematic topics among primary and secondary students. This study aims to investigate to what extent the primary school pupils apply fractional strategies to solve problems on number line. This study was conducted using a qualitative methodology. The data were collected from task-based clinical interviews. The subjects of this study were selected among the Year Five students in Malaysia. A total of eight students participated in this study. This study revealed three types of fractional strategies. They are (1) finding an interval in fractions on number line, (2) applying concepts of decimal and interchange with fraction, and (3) comparing values of fractions. The findings showed achieving fractions arithmetic proficiency is crucial in developing the knowledge of fraction magnitude representations on the number line.
