Teacher Notes:

Location is an important aspect of describing a spatial situation. To identify an object, we often need to indicate where it is; for example, we may say, “the rectangle or the desk is to the left of the table.” These positional descriptions sometimes involve measurements—for example, “the rectangle is one inch below the circle”—or relations—for example, “it is outside the circle but inside the square/at the top of the square on the right.”

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 different 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.2
