Geometrical Concepts from Constructions, Models, and Investigations
Rhombic Dodecahedron - Hidden Within or
Surrounding the Cube?
Joyce Frost and Kris Koch
Teacher Directions || Worksheet
WHAT IS IT?
Classroom activity illustrating the interconnections between a cube and a rhombic dodecahedron.
1-2 class periods
- Teacher classroom set of Zome™ tools (if available)
- If Zome™ tools are not available, each group of 4 students could use 96 clear standard sized drinking straws (24 for each person) and blue and yellow curling ribbon to build a total of 12 square pyramids per group.
- Student worksheet
- Increase students' and teachers' understanding of important geometrical concepts through the construction and analysis of three-dimensional models.
- Analyze and compare properties of the cube and its corresponding rhombic dodecahedron by dissecting and transforming the solid cube.
- Develop mathematical arguments about geometric relationships of the cube and its corresponding rhombic dodecahedron.
