The pandemic caused by COVID-19 forced a mandatory confinement throughout the planet, thus, teachers and students distanced themselves and caused the migration from face-to-face to virtual education. This drastic change in education greatly affected Peru, as technological tools were required to support the student in the learning process. For this reason, the educational software KINDERMAT was built, which is a web application that supports the learning of geometric shapes in preschool children. The research aims to determine how KINDERMAT influences the conceptual and practical learning of geometric shapes in children 5 years old. To achieve this, students from an Educational Institution in Peru are taken as a sample, dividing them into two groups: experimental group (GE1) and control group (GE2). A post-test is applied to both groups following a quasi-experimental design. Finally, it was shown that the KINDERMAT educational software positively influences learning in the students in the sample, since there is a 15.5% improvement in the learning of children who used the KINDERMAT educational software compared to children who did not use it.
