Abstract
Several studies have investigated how the formation of informal conjectures, and the dialogue they evoke, might influence young children?s learning trajectories, and enhance their mathematical thinking. In a digital environment, the visual output and its distinctive qualities can lead to interpretation and response of a particular nature. In this paper the notion of visual perturbance is explored, and situated within the data obtained, when tenyear-old children engaged in number investigations in a spreadsheet environment.
