Spatial Activity: Making 3-D Inferences
 Visualizing three-dimensional objects presented on the flat surface of a piece of paper or computer screen is challenging for many of us. For people with math disabilities this sort of spatial interpretation can be particularly problematic. And depending on the manner in which geometric information is presented, interpreting objects in the exact way a teacher intended may be next to impossible.

Consider the two figures shown below.
