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?
