It has been advocated that the search for patterns and their organization in mathematical language is a central component of mathematical thinking. Hershkowitz, Arcavi and Bruckheimer (2001) investigated problem solving processes of a "visual-pattern-problem" which start with visual strategies for reorganizing the visual pattern and ended in a formal algebraic expression as a solution. In this study we had decided to use the same problem for investigating also a process in an opposite direction: starting from a given algebraic expression, analyzing it in a way that uncovers the visual strategies which are behind the algebraic components of the given expression.
