"One of the goals of the geometry lesson sequence was to develop the students' spatial reasoning, which is an important aspect of geometry learning. In this challenge, you are to focus on the students' spatial reasoning and on how the activities used in the geometry lessons supported development of the students' sense and understanding of space.
To begin your investigation, watch as these two students figure out the number of cubes needed to fill two different boxes. The first box has dimensions 4x4x5, and the second box has dimensions 3x5x2."
