Unit 8: Geometry: Scale Figures and Cross Sections
Duration of Days: 9
1. How do scale drawings represent actual measurements through proportional relationships?
2. How do the faces of 3D figures relate to their 2D slices?
1. Use proportional reasoning to scale items and apply scale factor
2. Draw, construct and describe geometrical figures and describe the relationships between them
3. Identify the 2D figures created by a horizontal or vertical cross section of a 3D figure
