**Abstract**

This study presents the research conducted on the Greek Mathematics Primary textbooks about the notion of the sequences of rational numbers on the geometric model of the number line. In other words, which and how many representations have been used in the textbooks of primary school for the above notion. In addition, it is commenting on the frequency and kind of representations, as well their correlation with the difficulties students face, based on surveys. Results show that there is a limited scope of activities on Mathematics textbooks about the sequences of rational numbers on the geometric model of the number line in Greece.
