The purpose of this manuscript, in the form of organized notes and considerations that emerged from pilot studies conducted with children in the schools of Modena and Reggio Emilia and in those of the project "PerContare " (in the Italian provinces of Bologna, Reggio Emilia and Turin), is to lay the foundations to look at roles educational technology might play in the development of number sense, so that educators may become able to make informed choices when they wish to adopt some of these technologies in educational contexts. The first section will discuss aspects of the development of numerical skills, and in particular the important role that using fingers seems to play. Then I will introduce the idea of the mental number line, and how technology has a great potential for its correct development, and finally I will emphasize some cognitive aspects that technology has the potential to mediate successfully, adding an analysis of several existing applications in the light of theoretical considerations that emerged in the first three sections.
Questo testo si presenta in forma di appunti organizzati e considerazioni emerse da studi pilota, condotti con bambini nelle scuole di Modena e Reggio Emilia e in quelle del progetto "PerContare " (nelle province di Bologna, Reggio Emilia e Torino), con lo scopo di fornire delle basi con le quali guardare la tecnologia a servizio della didattica per lo sviluppo del senso del numero, in modo da poter attuare scelte informate in caso si adozione di queste tecnologie in ambiti educativi. Nella prima sezione vengono illustrati alcuni aspetti dello sviluppo di abilità numeriche, in particolare il ruolo importantissimo che sembrano giocare le dita. Viene poi, introdotta l'idea della linea numerica mentale, utile anch'essa per descrivere le potenzialità offerte dalla tecnologia per il suo sviluppo e, a seguire, vengono sottolineati alcuni aspetti cognitivi che la tecnologia ha la potenzialità di mediare con successo.

Abstract
The purpose of this manuscript, in the form of organized notes and considerations that emerged from pilot studies conducted with children in the schools of Modena and Reggio Emilia and in those of the project "PerContare " (in the Italian provinces of Bologna, Reggio Emilia and Turin), is to lay the foundations to look at roles educational technology might play in the development of number sense, so that educators may become able to make informed choices when they wish to adopt some of these technologies in educational contexts. The first section will discuss aspects of the development of numerical skills, and in particular the important role that using fingers seems to play. Then I will introduce the idea of the mental number line, and how technology has a great potential for its correct development, and finally I will emphasize some cognitive aspects that technology has the potential to mediate successfully, adding an analysis of several existing applications in the light of theoretical considerations that emerged in the first three sections.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
