We define 3D shapes as geometric figures that have three dimensions, width, depth and height. 3D shapes differ from 2D shapes because they have thickness. They are often thought of as solids, but can also be hollow, like an empty box. We classify 3D shapes by the number and size of their faces, the number of their vertices, and by the number and size of their edges.
Faces - these are the flat parts of the 3D shape.
Edges - these are the sides of the faces, where two faces meet.
Vertices (Vertex) - These are the corners or points of the shape.
Lots to remember so we decided to make it fun! We were learning and eating 3D shapes:
David didn't want to be photographed...sorry David :)
