Student workbook (30 pages), suggested
for grades: 1-3
Students build and learn to describe and draw pyramids, prisms,
anti-prisms and other more complex structures.
GWB-2"Nets
of 3-D Solids"
Student workbook (28 pages), suggested
for grades: 4-5
Students investigate nets that can, or cannot, be folded to form
pyramids and prisms. Students strengthen visualization and spatial
reasoning skills and eye-hand coordination.
GWB-3"Regular Solids and Tiles"
Student workbook (32 pages), suggested
for grades: 6-7
In the first part students follow one simple rule and discover how
to construct and analyze five Platonic Solids and three regular
tiles. The students practice 3-D drawing from perspective, decomposition
to nets and symbolic description. They discover and verify the Euler's
Equation.
In the second part students construct and explore Archimedean solids
and discover the concept of truncation.
GWB-4"Rotation
Symmetry in 3-D"
Student workbook
(34 pages), suggested grades: 7-8
Students discover and demonstrate rotation symmetry of the Platonic
solids. They discover important symmetry facts: solids look different
when viewed along different symmetry axes, one solid may possess symmetry
of more than one order and there are many equivalent symmetry axes.
Platonic solids are well suited for these explorations - as the most
symmetrical solids they give ample opportunity for repeated practice
leading to the integration of the concepts.

GWB-5 "Mirror
Symmetry in 3-D"
Student workbook, suggested grades:
7-8
Students discover and demonstrate mirror symmetry of the Platonic
solids and integrate the concept by ample practicing.
