Packages+and+Polygons


 * Overview**: Packages and Polygons is the first seventh grade book in the Geometry strand. The unit focuses on various shapes and their construction.
 * Section A**: In this section the students learn to identify various three-dimensional shapes and identify the two-dimensional patterns that are used to make the shapes.


 * Section B**: The students build bar models of three-dimensional shapes to identify faces, edges, and vertices. They also examine the stability of various structures created by these shapes.


 * Section C**: The students identify various properties of regular polygons including relationships that exist amongst interior angles.


 * Section D**: In this section the students construct models of regular polyhedra and investigate various properties and relationships. They apply Euler's formula (relationship between faces, vertices, and edges) and develop spatial visualization skills.


 * Section E**: The students use a variety of strategies to estimate and find the volume of various three-dimensional containers.
