Think about the student work and reflect on the following questions:

• What mathematical content does the Building Viewpoints problem entail?
• How is representation a critical part of communicating ones' thinking about this problem?
• How could students show what they have learned in the Building Viewpoints problem? What elements might be included in their presentations?
• What are some other ways that students might think about representing their ideas when solving similar problems involving spatial visualization?
