Teoría Algebraica de la Proporcionalidad

Section role: supports the 'Conectando Hallazgos con la Teoría Algebraica' section while the teacher formalizes the mathematical language based on student lab findings from the previous activity. Slides: (1) Title — 'Formalizando nuestros hallazgos'; (2) Proporcionalidad Directa — bullets: definition y = kx, meaning of constant k, algebraic identification; (3) Gráfica Directa — bullets: visualization of a straight line through the origin (0,0), slope as k; (4) Proporcionalidad Inversa — bullets: definition xy = k and y = k/x, product invariance, constant k; (5) Gráfica Inversa — bullets: visualization of the hyperbola curve, asymptotic behavior; (6) Comparación Práctica — bullets: side-by-side comparison of direct vs. inverse tables and equations; (7) Modelando una Situación Diaria — bullets: step-by-step example of setting up y = 2x from real-world data; (8) Conexión y Dudas — bullets: summarizing when to use each formula, bridging to upcoming individual application work. Closing slide: '¿Cómo distinguimos una relación directa de una inversa mirando solo su tabla de valores?' — hands control back to the teacher for Q&A.
