1. 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.

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

3. 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.

4. 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.
