2005), learners were given the two VMRs in Figure 10 with which to interact: a geometric solid (a), and a diagrammatic map of transitional relationships among a set of solids (b).

For instance, an MCT, Archimedean Kaleidoscope (Morey & Sedig, 2004b), allows learners to rotate 3D geometric solids.

FOR THE DOME of my observatory I decided to start with the dodecahedron, the regular

geometric solid that consists of 12 identical pentagons.

An examiner rejected a pair of the applicant's design patent applications after identifying the designs as being formed by the intersection of two geometric solids.

Thus, the combination of any two geometric solids in art would be found to be obvious, despite multidimensional variations, including their relative size and orientation.

Dubbed symmetrohedra, these

geometric solids result from the symmetric placement of regular polygons (see illustration on page 397).

Platonic solids, Archimedian solids, other

geometric solids, and the mathematical relationships related to these solids were the objects of study.

All teachers of the primary grades have watched children stack boxes, soup cans, and

geometric solids with great fascination.

Other activities include making curves with straight lines, creating a set of tangram pieces, tessellating squares into interesting patterns, constructing a Mobius strip, and putting together nets to build some basic

geometric solids.

One task involved handing out labeled

geometric solids to the children.
