The research presented deals with the process of learning rational numbers. Assuming that at the end of a successful learning process the formal routines taught at the school become useful for practical activities, we have documented the activities of children from different grade levels regarding school assignments and daily practical tasks. We document the participants' activities from their entrance to the 1st grade, where they have no school experience with fractions, all the way through the sixth grade, where they are expected to arrive at the fully satisfactory mastery of rational numbers. In analyzing the data, we examined how the formal routines for performing certain fractions-related school assignments changed over time and how (if at all) they converge with routines for daily practical tasks. In this paper, we present findings from two school tasks: (1) locating a fraction on the number line, and (2) naming a point on the number line.
