Represent three-dimensional figures using nets made up of rectangles and triangles, and use the nets to find the surface area of these figures. Apply these techniques in the context of solving real-world and mathematical problems.
Students explore cube nets in an effort to understand what properties are common to all nets that form a cube. Students work hands-on with nets and are then pushed to use their experience to visually determine whether other nets will form a given figures.
How can you find the perimeter and area of various polygons? What is surface area and how can you calculate it? What do students understand? What gaps do they have in their understanding? Students review and take the quiz.
What is going on in the problem? What are you trying to figure out? How can you use what you know to solve the problem? Students apply the skills they have learned throughout Unit 7 to complex tasks.
