This chapter focuses on number line segment activities taken from one session of the year-long intervention investigating how 4th grade students build fraction ideas (Schmeelk, 2010). The videotapes of the session provide data for a narrative that has been partitioned into an analytic, entitled “Imagining the Density of Fractions.” This analytic provides illustrations of the students ordering fractions on a number line segment between zero and one based on their rod models. The students, then, built their own personal number line representations of the segment between zero and one. This chapter references events from the analytic, entitled “Imagining the Density of Fractions” that is located in the Video Mosaic Collaborative (http://dx.doi.org/doi:10.7282/T3FJ2JKN).
