Spatial Reasoning
All Year A and B students work on a project called Impossible Solids. With experience, students discover the fun of communicating visually about objects in space. As they experiment, students begin to grasp the connection between a three-dimensional object and its representation on isometric dot paper. The aspect of perspective may not be evident to students when manipulating the cubes. Eventually, however, most students will notice that parallel edges of a rectangular prism are represented by parallel lines on the paper and the square faces are represented by rhombuses. They will also realize that shading enhances their drawings.
