Unit 5:

Extending to Three Dimensions

How are two dimensional and three dimensional objects related to each other?
4 weeks

Unit five is about describing, representing and using the relationships between two-dimensional and three-dimensional figures to model and solve problems arising in everyday life. Throughout the unit, students examine the relationships between 1-D, 2-D and 3-D geometric representations to determine which ones to apply in describing and modeling situations that are helpful in solving problems. Students study geometric objects by taking cross sections of compound 3-D objects, rotating 2-D figures in space, and analyzing the impact of dimensional changes to measurements, such as perimeter, area, and volume.

Essential Questions:

  • How are two dimensional and three dimensional objects related to each other?
  • How can we use geometric relationships to model the world and solve problems?

Unit Outline

8 Components

Every unit begins with an Initial Task and ends with a Balanced Assessment, both focusing on core mathematics of the unit. The core mathematics is developed through a series of resources around Big Ideas; as you move through the unit, keep students focused on how these ideas are connected and how they address mathematical problem solving. Before attempting the Balanced Assessment, students have an opportunity to synthesize their knowledge through a multi-day Formative Assessment Lesson and teacher-designed re-engagement lessons.
