Notes 3-D Shapes Base: Top and/or bottom of a figure. Bases can be parallel. Edge: The segments where the faces meet. Face: The sides of a three-dimensional shape. Nets: Are used to show what a 3-D shape would look like if we unfolded it.

Prisms Have Rectangles for faces Named after the shape of their Bases

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.
