Polyhedrons Essential Understandings: • Polyhedron is the name given to three dimensional polygons. • Poly means many and Hedron means face. So polyhedron translates to many faces. • There are two main types of polyhedrons: – Prisms: composed of 2 bases (any shape) and rectangular walls. – Pyramids: composed of one base (any shape) and triangular walls. • Polyhedrons are named for the shape of their bases, and this tells you how many walls they will have. • Examples:

Polyhedrons Essential Understanding: A polyhedron is a three dimensional figure with flat polygonal faces, straight edges, and sharp corners or vertices. • In sixth grade we focus on two main types of polyhedrons – Prisms: A prism is a polyhedron, with two parallel faces called bases. The other faces are always parallelograms. The prism is named by the shape of its base http: //www. mathsisfun. com/geometry/prisms. html – Pyramids: A pyramid is a polyhedron that has a base, which can be any polygon, and three or more triangular faces that meet at a point called the apex. https: //www. mathsisfun. com/definitions/pyramid. html

Polyhedron Nets Essential Understanding: Nets are used to find the surface area of a three dimensional figures. • Nets are two dimensional layouts of three dimensional figures. In this unit we will focus on nets of prisms and pyramids. • Nets for three dimensional shapes can be classified by identifying the base(s) – A prism will have two congruent polygonal bases, and three or more parallelogram faces. Example: – A pyramid will have only one polygonal base and three or more triangular faces. Example: – The number of faces a solid has is determined by the number of edges the base has. Example:

Surface Area of a Prism Essential Understanding: A prism will have two congruent polygonal bases and three or more parallelogram faces. • To calculate the surface area of a prism, begin by creating a net to illustrate the figure two dimensional. Example: • Next, carefully label all of the given dimensions. Example: • Then, simply use the net to find area of each individual face/base. A table should be used to ensure precision. Example: • Finally, add the areas of all faces to determine the total surface area.
