Learning goals: Sub-Unit 1: Area (Lessons 1–9 + Practice Day + Quiz) • Calculate the area of parallelograms and triangles. • Calculate the area of polygons by decomposing them into rectangles and triangles or by enclosing and subtracting. • Describe the relationship between a base of a parallelogram or triangle and its corresponding height using mathematically precise language. • Analyze strategies for determining the area of polygons using mathematically precise language. Sub-Unit 2: Surface Area (Lessons 10–14 + Practice Day) • Connect polyhedra with nets that represent them. • Calculate the surface area of polyhedra made up of rectangles and triangles. • Describe the polyhedron that can be assembled from a given net using mathematically precise language, including terms such as face, edge, prism, and pyramid. • Analyze strategies for determining the surface area of polyhedra using mathematically precise language, including terms such as face, edge, base, and height.
