This work is concerned with an analysis of how shared representations - notations that are manipulated by more than one person during a collaborative task - are used as resources to support that collaboration. The analysis is built on the concept of informational uptake: how information moves and is transformed between individuals via a graphical representation as well as a verbal chat tool. By examining patterns of such uptake, one can see ways in which the activity of two individuals is coupled and joined into a larger cognitive (and sometimes knowledge-building) activity distributed across the persons and representations they are manipulating.
