Abstract
Problem solving and argumentation are key-competencies in education. The mathematical education at school should give a strong contribution to the development of these competences. The promotion of problem solving and argumentation in mathematics is shared by several international standards. In this contribution, we will describe a project on problem solving and argumentation in primary and middle school, and we will underline that students’ argumentation in mathematical context is an important interpretative tool for teachers.

All’inizio dei nostri incontri di formazione, poniamo la domanda a insegnanti dei vari livelli scolari emerge quasi sempre come molti degli obiettivi esplicitati dagli insegnanti siano in comune tra i vari livelli scolari
La decisione di lavorare su problem solving e argomentazione è sicuramente impegnativa e, nella sua trasposizione in classe, necessita della realizzazione di alcuni aspetti, primo tra tutti la necessità che l’adulto (l’insegnante) si metta in gioco, prestando realmente attenzione alle spiegazioni dei bambini, sforzandosi dunque di ascoltare gli allievi, e parta dalle parole dei bambini per intervenire sulle difficoltà o rilanciare con nuove domande e questioni
