Apresentação: Conectando Ideias da Álgebra Prática à Teoria

Section role: supports the 'Conectando Ideias: Da Prática à Teoria' section while the teacher guides students through the transition from the geometric pool tile challenge to formal algebraic notation. Slides: (1) Title — 'Da Prática à Teoria: O Poder das Expressões'; (2) As Duas Caras da Mesma Moeda — bullets: comparing 4L + 4 and 4(L + 1) side by side from the group challenges; (3) Anatomia de um Termo — visual breakdown of coefficient and literal part using color coding (e.g., 5x where 5 is the coefficient and x is the literal part); (4) O Valor Numérico em Ação — bullets: step-by-step substitution of L = 10 into both expressions to prove they yield the same result; (5) A Propriedade Distributiva — bullets: showing how 4(L + 1) transforms into 4L + 4 algebraically; (6) Termos Semelhantes — bullets: what can and cannot be added, contrasting 3x + 2x with 3x + 2x²; (7) Conexão com o Futuro — bridging back to Section 2's patterns and setting up Section 4's individual checks. Closing slide: 'Se duas expressões dão sempre o mesmo resultado numérico, elas são irmãs gêmeas algébricas?' — hands control back to the teacher to lead the Q&A.
