Modelo Matemáticas 6º-11º
Razonamiento Geométrico
El Razonamiento Geométrico implica usar el pensamiento abstracto para definir, analizar y argumentar sobre formas y relaciones espaciales. Los estudiantes también deben ser capaces de formalizar estos argumentos en pruebas escritas. El conocimiento geométrico de los estudiantes proporciona representaciones concretas y modelos para conceptos matemáticos abstractos, que pueden servir como un punto de entrada a habilidades de pensamiento matemático de orden superior.
Ideas Principales
Los niños comienzan con un conocimiento geométrico intuitivo (por ejemplo, sobre forma y simetría) que se desarrolla a través de la exposición a eventos en el mundo. En la escuela, este conocimiento informal se amplía y se expande hacia una comprensión más formal de los conceptos geométricos, incluyendo:
Simetría: reflexión a lo largo de una línea (por ejemplo, doblar) dentro de una forma;
Congruencia: la relación entre formas a través de rotación, reflexión o traslaciones; y
Similitud: la relación entre formas cuyas lados son proporcionales y los ángulos son iguales.
El Razonamiento Geométrico se apoya en las Habilidades Espaciales, que permiten a los estudiantes comprender formas en dos y tres dimensiones y el espacio, y comunicar y argumentar sobre estos conceptos a través de diferentes canales, incluyendo la actividad sensoriomotora y corpórea.
