The mathematical performance of 193 Early Childhood Education students agedbetween 57 and 79 months (M=63.3, SD=3.7) from various schools was assessed usingthe TEMA-3. They were divided into three groups: two experimental groups and onecontrol group. Students in the experimental groups underwent a training program incognitive processes related to mathematical learning using Apps. A pre- and postintervention comparative analysis was conducted.The training program with apps showed significant gains in those students whohad low scores in the pre-assessment tests. As expected, students at higher levels alsoimproved with the training program. However, those students who started at an optimallevel of mathematical learning achieved a significant score improvement, especially inmeasures of formal mathematical thinking.The advantages derived from the use of these Apps, both inthe school environment and at home, are discussed.
