Conectando Pontos e Nomeando Formas: Apresentação

Section role: supports Section 3 ('Conectando Pontos e Nomeando Formas') while the teacher synthesizes the students' park projects onto the board and introduces formal geometric vocabulary. Slides: (1) Title — 'O que é um Polígono?'; (2) Revisiting the Park Projects — bullets: connecting common features from group designs, introduction of the formal definition of polygon as a closed flat figure with straight segments; (3) Anatomy of a Polygon — bullets: defining sides and vertices, showing vertex as the meeting point of two sides; (4) Naming the Family: Triangles and Quadrilaterals — bullets: Triangle (3 sides), Quadrilateral (4 sides) showing variety including square, rectangle, rhombus, and trapezoid; (5) Naming the Family: Pentagons and Hexagons — bullets: Pentagon (5 sides), Hexagon (6 sides) with natural and artistic examples; (6) The Circle Dilemma — bullets: why circles are flat but not polygons due to lack of straight sides; (7) Common Misconceptions — bullets: dispelling the myth that all 4-sided figures are squares or rectangles; Closing slide: 'Qual é a diferença fundamental entre um polígono e um círculo segundo o que aprendemos?' — sets up the individual evaluation in the next section.
