Big Ideas: Different figures are related because of the attributes they have in common. Shapes that belong to a subcategory share the attributes of the shapes in the larger category. This lesson builds on students' understanding of sorting geometric figures into categories and subcategories based on attributes. The task asks the students to explain how different geometric figures are related by explaining which attributes they share and which they hold alone. The task is set up as a geometric board game that allows students to pick multiple paths to the finish. Some routes allow students to focus solely on quadrilaterals, while other routes challenge students to compare the attributes of triangles. This lesson builds towards lessons where students build a hierarchy of two dimensional shapes and describe the relationships between shapes in a hierarchy. Vocabulary: attribute, property, category, sub-category, two dimensional, related, common attributes Special Materials: Optional: Sticky Notes or Note Cards (10-15 per student or for students who choose to use them)
