    Las diferentes caracterizaciones propuestas para el sentido numérico coinciden en la necesidad de promover el establecimiento de conexiones para el uso estratégico de los números racionales por parte de los estudiantes. El presente estudio sigue un diseño de estudio de casos dónde se analizan ocho sesiones de clase de un grupo de estudiantes de 12-13 años que estudian los números decimales. Los resultados muestran una relación entre la emergencia de tipos específicos de conexiones matemáticas y el posible desarrollo de componentes específicas del sentido numérico en los estudiantes. Se señala una especial relevancia de las conexiones de tipo “justificación” en la construcción de aspectos fundamentales del sentido numérico y se discuten oportunidades para refina modelos de referencia de las conexiones matemáticas.

    Several characterizations proposed for number sense coincide in the need to promote the es-tablishment of connections for the strategic use of rational numbers by students. This study follows a case study design for the analysis of eight class sessions of a group of 12–13-year-old students who study dec-imal numbers. Resultsshow a relationship between the emergence of specific types of mathematical con-nections and the possible development of specific components of number sense in students. A special rel-evance of “justification” type connections is pointed out in the construction of fundamental aspects of number sense. Opportunities to refine reference models of mathematical connections are also discussed.
