This research is part of a broader project, based on the proposal of early algebra, the main purpose of which is to explore the algebraic abilities displayed by primary school students in tasks involving a functional relationship. Our goals in this communication are two. First, to describe how third-grade students represent indeterminate quantities when expressing functional relationships. Second, to illustrate how students make use of the letter in such representations when this one is proposed as a representation for the independent variable of the function.
