Math: Geometry: Visual Spatial Skills

These sites focus on visual-spatial skills. Includes information about orthographic and isometric projections, rotation of objects from different axes, cutting planes and cross-sections, object reflection and transformation, and symmetry. There are suggested ideas, simulations, and activities that can be used to promote visual and spatial skills. There is a link to eThemes Resource on Geometry: Symmetry.
