The present research work entitled "Application of the software tool Abriltronic, based on the theory of Polya, to improve the ability to solve mathematical problems of the four basic operations in students of the 3rd grade of primary education in the I.E. Ramón Castilla Marquezado - Alto Trujillo ", was oriented by the general objective that was to determine if the application of Abriltronic Software Tool, based on the theory of Polya, manages to improve the ability to solve mathematical problems of the four basic operations._x000D_ We used the quasi experimental design, we worked with two sections of the I.E. Ramón Castilla Marquezado one directed to be our control group, which counted on 32 children and the experimental group with 30 children that is to say worked with a sample of 62._x000D_ After processing all the data and their presentation in tables, graphs and their description...
