De los objetos reales a la notación fraccionaria

Section role: supports the formalization section while the teacher introduces official terminology using the examples created by the students during the banquet challenge, bridging concrete object divisions with mathematical notation. Slides: (1) Title — 'La Lengua de las Fracciones'; (2) Del objeto al número — bullets: visual of a real pizza divided into 6 slices, transition to the numeric notation 1/6; (3) ¿Qué es una fracción? — bullets: definition using parts equal to the whole, connecting back to Section 2's geometric shapes; (4) El Denominador — bullets: definition as the total number of equal parts, why size matters, example with a chocolate bar divided in 4; (5) El Numerador — bullets: definition as the counted parts, example of taking 3 parts out of 4 (3/4); (6) La Línea Fraccionaria — bullets: visual breakdown of the bar position and its role; (7) Casos de la vida real — bullets: examples showing fractions in everyday contexts like juice glasses and clocks; (8) Advertencia matemática — bullets: non-examples where unequal parts fail to form fractions; (9) Comprobación rápida — bullets: interactive prompt to identify numerator and denominator from a projected image (e.g., 5/8); Closing slide: '¿Por qué necesitamos conocer el nombre exacto de cada parte antes de escribir una fracción?' — hands control back to the teacher to set up the individual assessment in the next section.
