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. Enjoy this presentation. Send feedback and suggestions to Don Fisher:by D. Fisher
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 thesame size and shape and lie inparallel planes BasesThe lateral faces are the faces thatare not the bases. Each lateralface is shaped like a parallelogram.Lateral Face
