Conectando o Concreto ao Símbolo: Frações e Quantidades

Section role: supports the 'Conectando os Pontos: Do Papel ao Símbolo' section while the teacher guides the whole class from physical manipulations to formal mathematical notation on the board. Slides: (1) Title — 'Da Tira ao Símbolo: O Significado da Fração'; (2) Revisgando as Dobras — bullets: visual of the paper strip divided into 4 equal parts, highlighting 3 painted parts to define the parts taken; (3) O Nome das Partes — bullets: introducing the terms Numerador and Denominador with color coding and clear definitions; (4) A Leitura das Frações — bullets: reading examples like meio, terço, quarto, quinto, with pronunciation guides for 5th graders; (5) O Enigma das 12 Fichas — bullets: step-by-step visual of calculating the fraction of a quantity, specifically showing 1/3 of 12 as dividing 12 items into 3 equal groups; (6) A Reta Numérica — bullets: a line from 0 to 1, showing how to locate 1/2 and 1/4 by equal spacing; (7) Fração como Divisão — bullets: connecting the fraction bar to the division operation (ex: 3/4 means 3 divided by 4). Closing slide: 'Como podemos calcular 1/4 de 20 fichas usando o que aprendemos hoje?' — sets up the independent assessment section that follows.
