Teacher Notes:

Visualization refers to a student’s ability to construct a single image or a series of related images, whether the image is of an object or a set of directions. Sometimes visualization involves imaging what an object looks like from a point of view, for example, from above rather than from the side. Other times, it involves predicting what an object might look like after it is turned or flipped or what the shadow of an object might look like. Visual memory—ability to recall what a shape looked like or what has been changed about a shape or an arrangement—is prerequisite to the ability to manipulate mental images, an important part of spatial sense.8
