Ítem Actividades matemáticaspara el desarrollo de procesos lógicos. Representar estructurasalgebraicas finitas y enumerables.(Universidad Pedagógica Nacional, 2013) Luque Arias, Carlos Julio; Jiménez Tafur, Haydee; Ángel Bautista, José LeonardoThis publication emerges with the purpose of determining which elementary mathematical activities favor the abstraction of algebraic structures and the mathematical process of representing them. Specifically, the authors attempt to identify the shortcomings revealed in the management of notions, properties and procedures related to the concept of structure, emphasizing on the mathematical activity of representing, that is, symbolizing, coding, decoding, visualizing and modeling. The authors of this important and practical work designed a set of seven activities, aiming to show academic environments of creative and pedagogical math work and to study and compare proposals known in other scenarios.Ítem Actividades matemáticas para el desarrollo de procesos lógicos. Contar e inducir.(Universidad Pedagógica Nacional, 2013) Luque Arias, Carlos Julio; Mora Mendieta, Lyda Constanza; Páez Ortegón, Jorge ÉdgarThe authors of this book seek the creative appropriation of the mathematical knowledge of the students, aiming to elevate their education. Therefore, the book proposes, from the very first chapter, the basic study of the symbols and rules of the number system and its operations, it also delves into the superior arithmetic operations with the respective properties and applications to cases in which an exercise knowledge of the students is required in order to propose solutions. Finally, the book analyzes the aspects that enable working with the method of mathematical induction, the different types or classifications of numbers and the use of tables and drawings to support and address daily cases in the classroom with respect to this method.Ítem Actividades matemáticas en una comunidad de ajedrecistas.(Universidad Pedagógica Nacional, 2020) Castillo Rojas, Christian Camilo; Vargas Guerrero, Claudia MarcelaEste trabajo de grado es el producto de una investigación centrada en identificar las actividades matemáticas que se evidencian en las expresiones verbales y no verbales de tres sujetos en sus prácticas como jugadores de ajedrez. Entiéndase actividad matemática como la define Bishop. Para hacer la identificación se generó, entre otras herramientas, una matriz con una variedad de criterios que permitieran asociar las expresiones verbales y no verbales de los sujetos de estudio con las actividades de conteo, medición o localización, particularmente.
