Base of a Prism - Either of the two parallel faces of a prism that are used to name it.  

Edge - A line segment where two faces of a 3-dimensional shape meet.

Extended Fact - A variation of a basic fact involving multiples of 10, 100, and so on.

Face - A flat surface that helps form the outside of a 3-dimensional shape.

Factor Pair - Two counting numbers that multiply together to give a specified product.  The specified product may have more than one factor pair.  

Multiple of 10 - A product of 10 and a counting number.  

Plot - To mark a location on a number line, graph, map, or chart.

Polyhedron - A closed 3-dimensional figure whose surfaces are all flat and formed by polygons.
