Will Penelope choose another bridegroom? Looking for an answer through signs

Young students working in group have to solve a problem related to Penelope’s legend. This paper analyses the students’ process to the solution. In particular, it investigates the genesis of written signs starting from specific gestures, progressively shared within the group. These gestures have various functions: understanding the situation, looking for patterns or rules, anticipating and accompanying productions of written representations, drawings and symbols necessary to solve the problem. Gestures are constitutive part of the APC space, a theoretical notion introduced as crucial element to properly describe what happens in the activity of the group.
