Summary: This paper is based on a case from the pilot of my PhD research project with a group of secondary students. I will argue that visual representations can work as a basis for reasoning about addition of fractions for low achieving students, similarly to what was shown by Nancy Mack regarding informal knowledge for multiplication of fractions.
