[en] The literature advises that teachers teach geometry through the use of digital devices due to the intrinsic motivation of most students when working in virtual educational environments, where they play an active and participating role. The objective of this research work was to evaluate the impact of the use of Information and Communication Technologies (ICT) and the Innovamat educational proposal in the teaching of geometry in the primary classroom. Didactic sessions were designed using Innovamat and geometric contents were worked on with students from 3rd, 5th and 6th grade of Primary Education. The results obtained from the survey carried out with Mentimeter revealed that the students showed an active and participatory attitude when using digital resources such as Innovamat, together with gamification activities such as the Tangram and geometric riddles. Although the sample size was limited and it was not evaluated in all primary grades, this study evidenced the great motivation of the students when carrying out mathematical activities with digital resources, which favored their understanding of geometric concepts. In addition, a development of their critical, active and argumentative thinking was observed when relating the contents with situations of daily life. These findings highlight the importance of integrating ICT and resources such as Innovamat in the teaching of geometry in primary school, promoting meaningful learning for students. However, it is necessary to expand the sample and carry out additional studies in different educational contexts and with other levels of Primary Education, as well as consider the inclusion of students with special educational needs.

[es] La literatura aconseja que los docentes ense?en geometr?a a trav?s del uso de dispositivos digitales debido a la motivaci?n intr?nseca de la mayor?a de los discentes al trabajar en ambientes educativos virtuales, donde desempe?an un rol activo y participante. El objetivo de este trabajo de investigaci?n fue evaluar el impacto del uso de las Tecnolog?as de la Informaci?n y Comunicaci?n (TIC) y la propuesta educativa Innovamat en la ense?anza de la geometr?a en el aula de primaria. Se dise?aron sesiones did?cticas utilizando Innovamat y se trabajaron contenidos geom?tricos con estudiantes de 3?, 5? y 6? de Educaci?n Primaria. Los resultados obtenidos de la encuesta realizada con Mentimeter revelaron que los alumnos mostraron una actitud activa y participativa al utilizar recursos digitales como Innovamat, junto con actividades de gamificaci?n como el Tangram y adivinanzas geom?tricas. Aunque el tama?o muestral fue limitado y no se evalu? en todos los cursos de primaria, este estudio evidenci? la gran motivaci?n de los alumnos al realizar actividades matem?ticas con recursos digitales, lo cual favoreci? su comprensi?n de los conceptos geom?tricos. Adem?s, se observ? un desarrollo de su pensamiento cr?tico, activo y argumentativo al relacionar los contenidos con situaciones de la vida cotidiana. Estos hallazgos resaltan la importancia de integrar las TIC y recursos como Innovamat en la ense?anza de la geometr?a en primaria, promoviendo el aprendizaje significativo de los estudiantes. Sin embargo, es necesario ampliar la muestra y realizar estudios adicionales en diferentes contextos educativos y con otros niveles de Educaci?n Primaria, as? como considerar la inclusi?n de estudiantes con necesidades educativas especiales.
