The other question is, are you looking for examples of pyramids in what passes for the Real World, or are you looking for three-dimensional models of pyramids, or both? (There are different kinds of pyramids, of course.)
three dimensional examples...i have solid wood examples of cylinder, rectangular prism, sphere,etc but not a pyramid...i was trying to think of something I could bring in to show instead of showing a two dimesional one from a piece of paper...
A prism isn't a pyramid. A prism has bases that can be congruent triangles or rectangles or hexagons or whatever, and the faces between the bases are rectangular or parallelogramic - so a Droste chocolate pastilles box is a hexagonal prism. A pyramid has one base that can be a triangle or rectangle or hexagon or whatever, and the faces are triangles.
Here are a couple of incredibly cool Web sites that might help. The first one is full of the most astonishing paper models...

holy crap...where were you when i was taking the praxis?
You could build one..... We had to build a Dodechohedron for our final "teacher math class" at UW-Madison-- I can let the secret out now (years later---well NOT THAT MANY YEARS)-- I was totally wasted when I was building mine in the hallway of my dorm drinking vodka/peach puker/OJ--- I think I got the best grade of my three "Math For Teachers" classes on that one...
