20 lessons to help your students improve their Spatial Awareness, understand solids and volume, move beyond 2-D, and experiment with symmetry. The designs range from 12 to 96 cubes, including unseen cubes (multi-layered), rows and columns, and missing cubes (tunnels and arches). These activities work well for the whole-class, but they are also perfect for independent or partner-work at math centers.
