Prisms Fun with by D. Fisher
This activity can be done with powerpoint only, but it is much better if the students practice with paper prisms or models made of drinking straws, etc. Besides learning the names of various prisms students can practice “algebraic reasoning.” They can generate sequences and make predictions about patterns. Enjoy this presentation. Send feedback and suggestions to Don Fisher: by D. Fisher

Three dimensional figures are figures that enclose a space.
Polyhedrons – a three dimensional figure in which each surface is shaped like a polygon.

Polyhedron The parts of a polyhedron have special names.
Face: a flat surface that is shaped like a polygon. Edge: the segment formed by the intersection of two faces. Vertex: a point where three or more edges intersect.

Prism A prism is a polyhedron with two faces
(called the bases) that have the same size and shape and lie in parallel planes Bases The lateral faces are the faces that are not the bases. Each lateral face is shaped like a parallelogram. Lateral Face

Vertices (points) 6 Edges (lines) 9 Faces (planes) 5
Triangular Prism Vertices (points) 6 Edges (lines) 9 Faces (planes) 5 The base has 3 sides.

The base has sides. 4 Vertices (points) 8 Edges (lines) 12
Rectangular Prism The base has sides. 4 Vertices (points) 8 Edges (lines) 12 Faces (planes) 6

The base has sides. 5 Vertices (points) 10 Edges (lines) 15
Pentagonal Prism The base has sides. 5 Vertices (points) 10 Edges (lines) 15 Faces (planes) 7

The base has sides. 6 Vertices (points) 12 Edges (lines) 18
Hexagonal Prism The base has sides. 6 Vertices (points) 12 Edges (lines) 18 Faces (planes) 8

The base has sides. 8 Vertices (points) 16 Edges (lines) 24
Octagonal Prism The base has sides. 8 Vertices (points) 16 Edges (lines) 24 Faces (planes) 10
