Properties of Quadrilaterals and Shapes

Mrs. Leamon guides students through an exploration of quadrilaterals, focusing on squares, rectangles, parallelograms, and rhombuses. Using toothpicks, students build and transform shapes, analyzing properties like angles and side lengths. The lesson emphasizes the relationships between different quadrilaterals, using diagrams to illustrate how squares, rhombuses, and parallelograms fit within the broader category of quadrilaterals. Students learn to classify shapes based on their properties and understand the hierarchy of these geometric figures.
